- Description: A recent (Feb.-Mar., 1996) trip to the Chagos Archipelago, central Indian Ocean, by one of us (RCA) resulted in 51 new records of fishes for the islands. In addition, another 29 new records were discovered either in the collections of the National Museum of Natural History at the Smithsonian Institution, or were gleaned from the literature. In total, 80 new records for Chagos are reported here. The checklist by Winterbottom et al. (1989) recorded 703 species from Chagos, that total is raised to 773 species. Eighty-nine changes in nomenclature from that used in the 1989 list are documented. Three geographic localities (Indo-Pacific, Indo-west Pacific and marginally on the Pacific plate, and Indo-west Pacific) account for just over 80% of the fish fauna. The five most speciose families (numbers of species in parentheses) are the Gobiidae (98), Labridae (63), Serranidae (50), Muraenidae (41) and Pomacentridae (38), and these together account for 38% of the total fish fauna. , Rhodes University Libraries (Digitisation)

- Description: The recruitment of juvenile marine fishes into the Knysna and Swartvlei estuaries was monitored over 30 months using seine, scoop and cast nets. The relative abundance, seasonality and growth of the dominant species are presented, and includes the Cape stumpnose Rhabdosargus holubi, white steenbras Lithognathus lithognathus, blacktail Diplodus sargus, strepie Sarpa salpa, Cape moony Monodactylus falciformis, southern mullet Liza richardsonii, groovy mullet Liza dumerilii, striped mullet Liza tricuspidens, flathead mullet Mugil cephalus, freshwater mullet Myxus capensis and leervis Lichia amia. Information on a further 12 species is also provided. Recruitment of most fish species into the Swartvlei and Knysna estuaries reaches a peak during summer, which coincides with maximum food resource availability and corresponds to the time when systems along this section of the coast are often open to the sea. Artificial winter breaching of the Swartvlei mouth has occurred in the past, and has generally led to the premature closure of the system and loss of the ‘head’ of water needed for the summer opening. This type of mouth manipulation leads to reduced availability of estuarine nursery areas for marine fishes along the southern Cape coast. Comparisons between the recruitment of juvenile fishes into the Knysna and Swartvlei estuaries indicate that higher densities of most species were recorded in the former system. This is attributed mainly to the fact that the Knysna mouth is deep, permanently open, and has a strong marine influence when compared to the shallow, narrow and seasonally closed Swartvlei mouth. However, in a regional context both Knysna and Swartvlei are large, unpolluted systems, which serve as important nursery areas for many species of fish. On this basis alone, these contrasting estuarine systems should be allocated the highest possible conservation status. , Rhodes University Libraries (Digitisation)

- Description: The physical environment and ichthyofauna of 10 estuaries, the East Kleinemonde, Klein Palmiet, Great Fish, Mtati, Mpekweni, Mgwalana, Bira, Gqutywa, Ngculura and Keiskamma, was sampled over a four year period. The ichthyofauna of each estuary was sampled once during winter and once during summer in that period, with the physical environment being sampled on two occasions per season. This investigation provides baseline ichthyofaunal and physical information for these estuaries, the majority of which have never been studied before. The fish data presented for these systems includes species composition, relative abundance, richness and diversity, longitudinal distributions and length frequency data. Descriptions of the physical environment within each estuary are also presented. The permanently open estuaries had a greater proportion of marine and freshwater species relative to the temporarily open/closed systems which were dominated by marine species dependent on estuaries and estuarine resident species. The permanently open estuaries had a higher Margalef's species richness index relative to the temporarily open/closed systems but the Shannon-Wiener species diversity index did not follow any discernible trend. There were minor longitudinal distribution trends when analysing the community as a whole, with patterns for individual species being more pronounced. The length frequency histograms for estuarine resident species differed between estuary types, while those for the marine migrant species were similar in the different estuary types.\ , Rhodes University Libraries (Digitisation)

- Description: Part 1: The nature of the barriers separating the Lake Malawi and Zambezi fish faunas: The nature of the barrier separating the ‘Lake Malawi’ from the ‘Lower Zambezi’ fish faunas was investigated by electrofishing the 145 km stretch of the Shire River surrounding the Murchison cataracts. The study shows that the lowermost element of the cataracts, the Kapachira Falls, is an absolute physical barrier to upstream movement of ‘Lower Zambezi’ species. The barrier to downstream movement by ‘Lake Malawi’ species is largely ecological and has two components, the fluviatile nature of the Upper and Middle Shire and especially the torrential nature of the cataracts, which are unsuitable for lacustrine species, and competition with the ‘Lower Zambezi’ fauna of the Lower Shire by the few species which succeed in negotiating the cataracts. , Part 2: An annotated checklist of the fish fauna of the River Shire south of Kapachira Falls, Malawi: The Shire River drains Lake Malawi and is a major tributary of the Lower Zambezi River. Sixty-one species of fish have been recorded in the lower reaches which are separated from the lower Shire basin by the Kapachira Falls and from the ‘East Coast River’ fauna present in the Upper Ruo River by the Zoa Falls. The fauna is essentially similar to that of the Lower Zambezi, although some Lake Malawi endemics occur sporadically in the upper part of the flood plain. , Rhodes University Libraries (Digitisation)

- Description: The publication of a new phase of research on the fishes of the Okavango drainage starts with this account which gives the valid names and broad distribution patterns of all species known from the system. Eighty species and subspecies are recognised, of which at least two (Parakneria fortuita Penrith; Serranochromis gracilis Greenwood) are endemic. Notes on early collections, synonymy, taxonomic status and distribution are given. New synonyms are recognized under Aplocheilichthys hutereaui (A. schalleri), Aplocheilichthys johnstoni (Haplochilus carlislei) and Ctenopoma multispinis (Ctenopoma machadoi) respectively. Recently published taxonomic changes are incorporated including two genera (Mesobola and Afromastacembelus), a species Serranochromis (Sargochromis) gracilis and the re-allocated Amphilius uranoscopus. The Zambezian Hemichromis species is re-identified as H. elongatus. A number of unresolved taxonomic problems are pointed out and certain dubious records are excluded from the checklist. The Okavango has a diverse fish fauna with tropical affinities. Many fish species are poorly studied. Man-induced threats to the continued natural functioning of this complex and dynamic system, especially large-scale water abstraction, overgrazing, deforestation and biocide spraying to eliminate tsetse fly, make it imperative that studies on the nature and role of the fishes are continued. , Rhodes University Libraries (Digitisation)

- Description: The gobiid fish genus Gnatholepis Bleeker is characterised as follows: dorsal-fin rays VI+I,10-12, the spines slender, none filamentous; anal-fin rays I,11-12; pectoral-fin rays 14-19, none free of membrane; pelvic disc with a frenum; scales on body largely ctenoid, 28-31 in longitudinal series; gill-rakers short, 1 + 3-4; anterior interorbital pores 2; sensory papillae on cheek primarily in a pattern of 4 or 5 vertical rows; body moderately elongate, the depth 3.8-5.4 in SL; head and body compressed; dorsal profile of head initially near-vertical, often with a slight anterior protuberance above upper lip; lower lip with a ventral flap on side of jaw; mouth inferior, the gape slightly oblique; teeth anteriorly in jaws in several rows, the outer row in upper jaw as slender well spaced canines (outer row of teeth at front of lower jaw may or may not be caniniform); tongue bilobed; gill opening ending slightly below level of lower edge of pectoral-fin base; caudal fin rounded, usually longer than head; a dark line extending ventrally from eye, sometimes with one or more side branches. Of the 21 nominal Indo-Pacific species that have been described in Gnatholepis, only 5 are recognised as valid. G. anjerensis (Bleeker), for which a neotype is described, occurs from East Africa and the Red Sea to the Hawaiian Islands and French Polynesia [synonyms include G. deltoides (Seale), G. knighti Jordan and Evermann, and G. corlettei (Herre)]. G. cauerensis (Bleeker) is provisionally divided into 4 subspecies, mainly by modal differences in pectoral-ray counts and slight colour variation: G.cauerensis cauerensis from East Africa to the Society Islands (G. scapulostigma Herre and G. inconsequens Whitley are synonyms); G. c. australis from Rarotonga, Cook Islands to the Pitcairn Islands; G. c. hawaiiensis from the Hawaiian Islands; and G. c. pascuensisfrom at Easter Island. G. davaoensis Seale, also provided with a neotype and description, ranges from the Ryukyu Islands to the Solomon Islands, Papua New Guinea, and Indonesia (G. gemmus Herre is a synonym). G. gymnocara, n. sp., is described from 26 specimens from shallow water of Queensland and the Northern Territory, Australia; it is unique in having 12 anal-fin soft-rays, prepectoral scales, no scales on cheek and opercle, median predorsal zone naked or with only a few small scales across its anterior part, and a large black spot on fourth interspinous membrane of dorsal fin in males. Gnatholepis sp., also a new species from northern Australia, will be described by Helen K. Larson; it is distinct in having 10 dorsal soft-rays, 15-17 pectoral-fin rays, no scales on cheek, opercle, median predorsal zone, or prepectoral area; and the last 2 to 4 mid-lateral blotches of the male dark brown to black. The count of pectoral-fin rays is the most useful meristic character to separate the species and subspecies of Gnatholepis: G. anjerensis, with 14-17 rays, has a strongly modal count of 16; G. cauerensis cauerensis and G. c. hawaiiensis have 16-19 rays (strongly modal 17); G. c. australis has 17-19 rays (modally 18); G. c. pascuensis has 18 or 19 rays, modally 19; G. davaoensis has 15-17 rays, modally 17. , Rhodes University Libraries (Digitisation)

- Description: An annotated checklist of the species of the fish families Labridae and Scaridae is presented; 541 valid species are recognized, including 68 genera and 453 species of labrids and 10 genera and 88 species of scarids. Thirty undescribed species of wrasses and two undescribed parrotfish species are also included. A list of nominal species is given, with their present assignments; nominal species of uncertain status are placed as incertae sedis and listed separately. A list of nomina nuda is also provided. The valid genera and species are listed alphabetically, with their synonyms and distributions. Examination of the original descriptions and type material (when extant) of previously unplaced nominal species of labroid fishes led to identification of 69 new synonyms. The generic names Artisia de Beaufort, 1939 and Emmeekia Jordan & Evermann, 1896 are here recognized as new synonyms of Halichoeres Ruppell, 1835. For the Labridae, 65 new synonyms of valid species are listed. Labrus psittaculus Richardson, 1840, a valid species of Pseudolabrus, is a primary homonym of Labrus psittaculus Lacepede, 1801; the next available name for this species is Labrichthys rubicunda Macleay, 1881 and the new combination Pseudolabrus rubicundus is proposed. The following new combinations are included: Pseudojulis inornatus Gilbert, 1890 is a valid species of Pseudojuloides; Xyrichtys perlas Wellington et al., 1994 is a valid species of Novaculichthys. For Scaridae, Sparus abildgaardi Bloch, 1791 is a senior synonym of Sparisoma chrysopterum (Bloch & Schneider, 1801), but a request of the International Commission has been made to reject abildgaardi in order to conserve S. chrysopterum; and Scarus visayanus Herre, 1933 is a new synonym of Scarus tricolor Bleeker, 1847. Pseudoscarus microcheilos Bleeker, 1861 is a synonym of Chlorurus strongylocephalus (Bleeker, 1854). , Rhodes University Libraries (Digitisation)

Paracyttopsis scutatus Gilchrist & von Bonde and Zen itea (Jordan & Fowler) are shown to be junior synonyms of Cyttopsis roseus (Lowe). Zeus japonicus Valenciennes and Zeus australis Richardson are considered synonyms of Zeus faber Linnaeus; there seems to be no basis for recognition of subspecies in this wide-ranging species. Zenopsis ocellatus (Storer) is placed in the synonymy of Zenopsis conchifer (Lowe). A key to the families of zeiform fishes is presented, and diagnosis for those families represented in South African waters are given.

Dinopercidae, a new family for the Percoid marine fish genera Dinoperca Boulenger and Centrarchops Fowler (Pisces: Perciformes)

- Description: The Genus Dinoperca was erected by Boulenger (1895) for the Northern Indian Ocean species Hapalogenys petersi Day and assigned to the Family Serranidae. Boulenger (1903) described a second species, D. queketti, from South Africa. Most subsequent authors have accepted the placement of Dinoperca in the Serranidae, but Johnson (1983) removed it from the Serranidae to the taxonomic limbo of “Incertae sedis’’. Centrarchops Fowler (1923), with a single West African species, was originally assigned to the Serranidae and has been treated by subsequent authors in the Serranidae. The osteology, myology and the otolith (sagitta) of D. petersi reveal no characters that would relate Dinoperca to any particular family of percoids. Furthermore, the presence or absence of certain characters preclude Dinoperca and Centrarchops from the Family Serranidae, and the superfamilies Haemuloidea, Lutjanoidea and Sparoidea. Two features appear to be uniquely derived characters (synapomorphies) justifying a separate family for Dinoperca and Centrarchops: (1) Frontal bones bearing a high median crest that articulates posteriorly with the supraoccipital crest and is cleft dorsally by a narrow median sulcus extending ventrally to the roof of the brain cavity. (2) Large swim-bladder with three pairs of large intrinsic muscles. , Rhodes University Libraries (Digitisation)

Furthermore, the presence or absence of certain characters preclude Dinoperca and Centrarchops from the Family Serranidae, and the superfamilies Haemuloidea, Lutjanoidea and Sparoidea. Two features appear to be uniquely derived characters (synapomorphies) justifying a separate family for Dinoperca and Centrarchops: (1) Frontal bones bearing a high median crest that articulates posteriorly with the supraoccipital crest and is cleft dorsally by a narrow median sulcus extending ventrally to the roof of the brain cavity. (2) Large swim-bladder with three pairs of large intrinsic muscles. , Rhodes University Libraries (Digitisation)

- Description: The fishes of three small Natal estuaries, the Mhlanga, Damba and Zotsha were sampled over a period of two years. A total of 68 fish taxa representing 24 families, 39 genera and 55 species were captured during this study. Forty seven fish taxa were recorded in the Mhlanga estuary of which Gilchristella aestuaria, Oreochromis mossambicus, Valamugil cunnesius, Valamugil sp. and juvenile mugilids numerically dominated. In terms of biomass, O. mossambicus, V. cunnesius, Liza alata, Myxus capensis and Mugil cephalus dominated the ichthyofauna of the Mhlanga system. In the Damba estuary, 24 fish taxa were recorded, the most abundant being Glossogobius callidus,M. capensis and 0. mossambicus. M. capensis, M. cephalus, O. mossambicus and G. callidus dominated the fish biomass captured in the Damba system. A total of 56 fish taxa were recorded in the Zotsha estuary during this study, with the ichthyofauna numerically dominated by juvenile mugilids, G. aestuaria, O. mossambicus, Rhabdosargus holubi, Terapon jarbua, Ambassis productus and G. callidus. The species which dominated the fish biomass in the Zotsha system were 0. mossambicus L. alata, Valamugil robustus, V. buchanani, M. capensis, M. cephalus and V. cunnesius. Classifying the species according to whether they were resident estuarine, freshwater, estuarine-dependent marine or marine species revealed that the first three groups were all well represented in the systems. Oreochromis mossambicus was the dominant freshwater species in all three estuaries. Gilchristella aestuaria and Glossogobius callidus were the principal estuarine species in the Mhlanga and the Damba respectively, with G. aestuaria, A. productus and G. callidus being the dominant estuarine species captured in the Zotsha. The principal estuarine-dependent marine fishes captured in the Mhlanga were V. cunnesius, Valamugil sp., juvenile mugilids, M. capensis, M. cephalus and L. alata. In the Damba, M. capensis and M. cephalus were the dominant estuarine-dependent marine species and in the Zotsha juvenile mugilids, R. holubi, T. jarbua, M. capensis, V. cunnesius, V. robustus, M. cephalus, L. alata and V. buchanani were the principal estuarine-dependent marine species. The results of this study indicate that the estuaries are dominated at different periods by different assemblages of fishes. This is linked to the spawning and migration patterns of the various species as well as the hydrological regime of each estuary. During the winter these systems are normally closed with relatively deep waters and high food resource and habitat availability. Freshwater and estuarine species mainly inhabit the upper reaches of the systems while estuarine-dependent marine species, which dominate the fish community, mainly occupy the middle and lower reaches. When these estuaries open with the onset of the spring/summer rains, adult and sub-adult estuarine-dependent marine species emigrate to the marine environment and juveniles begin recruiting into the systems. Spring is also the peak breeding period of resident estuarine and freshwater species, resulting in an increase in the contribution of these fishes to the overall ichthyofauna during this period. When closed estuaries open the water level falls and this results in the fishes concentrating in the lower reaches of the system where moderate water depths are present, thus further contributing to an increase in the proportion of freshwater and estuarine species in this region. The breaching of closed estuaries also results in a reduction in food resources and habitat availability. Competition and possible increased vulnerability to avian predation (due to the shallow nature of the systems), may contribute to a decrease in the proportion of estuarine and freshwater species in summer. The prolonged recruitment of Of-juveniles of estuarine-dependent marine species results in an increase in the proportion of these fishes present in the estuaries during summer. In autumn, the systems normally close, water levels rise and available food resources and habitat increase. This allows the redistribution of freshwater and estuarine species upstream, leaving estuarine-dependent marine species to dominate the middle and lower reaches. Although temporarily open/closed estuaries along the Natal coast may not be as diverse as permanently open estuaries in terms of their ichthyofauna, their importance must not be underestimated, since by providing a series of sheltered habitats along the coast they may contribute significantly to the viability of estuarine-dependent marine fish stocks. , Rhodes University Libraries (Digitisation)

- Description: Study of the biology, anatomy and taxonomy of the sciaenid fishes of the genus Argyrosomus from South Africa and Namibia revealed that three species were confused under the name ‘Argyrosomus hololepidotus (Lacepede, 1801)”. Comparison of morphometric and meristic data, otoliths, swim-bladders, drumming muscles, and other morphological features, of specimens from southern Africa, Madagascar, the Mediterranean Sea, the eastern Atlantic Ocean, Japan and Australia, established that the “A. hololepidotus” of recent authors is a complex of four species: A. japonicus (Temminck & Schlegel, 1843), which occurs off southern Africa, Japan and Australia; A. inodorus sp. nov., which is known from Namibia to the Kei River (32°40’S) on the east coast of South Africa; A. coronus sp. nov., which is known from central and northern Namibia and Angola, and A. hololepidotus, which appears to be endemic to Madagascar. These four species are compared with A. regius (Asso, 1801) of the Mediterranean and eastern Atlantic, A. thorpei Smith, 1977 from South Africa, Mozambique and the west coast of Madagascar, and A. beccus Sasaki, 1994 known only from Durban harbour. To promote stability in the nomenclature and to resolve the confusion in the taxonomy of Argyrosomus species, neotypes are selected for A. hololepidotus and A. japonicus. The biology, distributions and fisheries of six species are reviewed. Distribution patterns for the southern African species and a key to the seven species known from Africa and Madagascar (A. regius, A. japonicus, A. inodorus, A. coronus, A. thorpei, A. beccus, and A. hololepidotus) are provided. The composition and distinction of the genus Argyrosomus are briefly discussed. , Rhodes University Libraries (Digitisation)

- Description: The osteology and swim bladders of the perciform family Apogonidae are surveyed at the generic level based on the examination of more than 150 species. Three subfamilies are recognized—Epigoninae, Apogoninae and Pseudaminae. The genera of Epigoninae are not treated. The Cheilodipterinae and the Siphaminae are not recognized as subfamilies and the Synagropi- nae are removed from the Apogonidae to the Percichthyidae. Descriptions of 19 genera and 14 subgenera are given. Forty-three genera are placed in synonymy and three new subgenera are proposed: Pristicon, Verulux and Zapogon. Keys to the three subfamilies and to the recognized genera and subgenera in the Apogoninae and Pseudaminae are presented. Discussions of the evolution of functional bony units within the Apogonidae are linked with trends seen in the beryciform-percoid transition and continuing changes exhibited by living percoids. The evolution and relationships of the living genera in the Apogoninae and Pseudaminae are treated and their zoogeography is briefly examined. , Rhodes University Libraries (Digitisation)
