  • 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: Various and disparate opinions have been expressed with regard to the phylogenetic affinities of Pseudocrenilabrus, a seemingly generalized and primitive haplochromine genus. These views are reconsidered and rejected. Instead, it is suggested that Pseudocrenilabrus is a derived and paedomorphic taxon evolved from a generalized haplochromine ancestor such as would be represented amongst extant African cichlids by a species of the genus Astatotilapia; for the moment it is not possible to identify a sister group more precisely. The suggestion that Pseudocrenilabrus is a paedomorphic taxon is based on certain Osteological and dental features, particularly the reductional trend manifest in the infraorbital bones of its three constituent species. A new diagnosis and synonomy are provided for the genus, together with notes on its anatomy, osteology and meristic features. , Rhodes University Libraries (Digitisation)

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)

  • Description: Online version of original print edition of the Special Publication of the J.L.B. Smith Institute of Ichthyology; No. 38 , Recent collecting in the Malawi lakes Chilwa and Chiuta has revealed a new haplochromine cichlid fish, Astatotilapia tweddlei, which is described and illustrated. It is distinguished from most members of this genus by an elongate, rounded caudal fin. Although having a distinctly different colour pattern and more slender pharyngeal bone, it shows a greater similarity to A. paludinosa, known only from the Malagarasi Swamp 1200 km to the north in the Zaire ichthyofaunal province, than it does to members of this genus from the closely adjacent Zambezi province from which this wetland system, in the East Coast province is separated by only some 50 km.

  • Description: Two genera of Squirrelfishes of the subfamily Holocentrinae are found in the Indo-Pacific region: Neoniphon (Flammeo of recent authors) and Sargocentron (Adioryx of most recent authors). A total of 19 species of these two genera occur in the Indian Ocean west of the southern tip of India: Neoniphon argenteus, N. aurolineatus (Flammeo scythrops Jordan & Evermann and Holocentrus anjouanae Fourmanoir are junior synonyms), N. opercularis, N. aurolineatus, Sargocentron caudimaculatum, S. diadema, S. ittodai (first records for the Red Sea and western Indian Ocean), S. macrosquamis (recently described from the Red Sea and Amirante Group, Seychelles, the range here extended to Kenya, Mozambique, Mauritius, and the Chagos Archipelago), S. melanospilos (usually misidentified as cornutum which is known only from the Indo-Malayan region), S. microstoma (known in the region only from Maldive Islands and Astove Island), S. praslin (usually not distinguished by authors from S. rubrum; Holocentrum marginatum Cuvier is a synonym), S. punctatissimum (has priority over lacteoguttatum due to selection by first revisor, Bleeker, 1873), S. rubrum, S. seychellense (an insular western Indian Ocean species), S. spiniferum (Holocentrum melanotopte- rus Bleeker is a junior synonym), S. tiere (Holocentrum elongatum Steindachner is a junior synonym), S. tiereoides (a new western Indian Ocean record), S. violaceum, and a new species, S. inaequalis (closely allied to macrosquamis Go- lani, 1984, differing in variable Spination of preopercle, modally one fewer pectoral ray, fewer average number of lateral-line scales and a more elongate body). S. inaequalis is described from a total of 7 specimens from the Chagos Archipelago, Seychelles and Comoro Islands. S. melanospilos is recorded for the first time from the Red Sea where it appears to be subspecifically distinct from populations elsewhere in the Indo-Pacific region (no subspecific name proposed). Holocentrum macropus Gunther, allegedly collected at Mauritius, is a misidentification of the Atlantic Holocentrus ascensionis (Osbeck). A lectotype is selected for S. microstoma. Neotypes are designated for S. praslin and S. rubrum. Colour photographs of fresh specimens of all of the species except S. macrosquamis are presented. , 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: Dawson, C.E. 1981. Review of the Indo-Pacific Pipefish Genus Doryrhamphus Kaup (Pisces: Syngnathidae), with Descriptions of a New Species and a New Subspecies. Ichthyological Bulletin of the J.L.B. Smith Institute of Ichthyology, No. 44, 27 pages, 17 figures. Doryrhamphus, a genus of trunk-pouch pipefishes commonly associated with rock or coral habitats, is diagnosed and a key is provided to the five species and five subspecies recognized. The genus Dentirostrum Herald and Randall is synonymized with Doryrhamphus, treated species and subspecies are diagnosed and illustrated, distribution (based on material examined) is delineated and comprehensive synonymies are provided. The genus includes two species groups which, (in subadults and adults) differ in having either one or two spines on principal ridges of the posterior predorsal rings. Species of the single-spine group are distinguished by differences in meristic values and preserved coloration, as well as by the presence of one or two ventrolateral projections on the snout of males, or the absence thereof. Species of the two-spine group are distinguished by differences in meristic values and preserved coloration, as well as by the presence of either one or two spines on principal ridges of tail rings. The single-spine group includes the type-species, D. excisus (three subspecies), with one ventrolateral projection on snout in males, A japonicus with no projection on snout, and D. bicarinatus n. sp. with two projections on snout. Doryrhamphus e. excisus (a senior synonym of D. melanopleura), with modally 17-18 trunk rings ranges from eastern Africa and Persian Gulf to the west coast of the Americas. This pipefish, the most widely distributed syngnathid, exhibits some west-east clinal increase in counts of total rings and dorsal-fin rays. Doryrhamphus e. abbreviatus n. ssp. is a Red Sea endemic characterized by modally 16 trunk rings as well as by 26-28 total rings and 18-20 dorsal-fin rays. D. e. paulus (Revillagegido Is., Mexico) shares the modal count of 16 trunk rings, but has 30-32 total rings and 23-27 dorsal-fin rays. D. japonicus (19-20 trunk rings) is known only from the main islands of Japan, whereas D. bicarinatus (16 trunk rings) is known from Indian Ocean coasts of South Africa and Mozambique. The two-spine group includes D. negrosensis (2 subspecies) with 2 spines on ridges of tail rings in subadults and adults and A janssi (one spine on ridges of tail rings. A n. negrosensis (modally 15 trunk and 29 total rings) is known from Borneo to the Ryukyu Is. and southeastward to the New Hebrides, excluding Australia. D. n. malus (modally, 16 trunk and 31 total rings) is an Australian Great Barrier Reef endemic. D. janssi, with more tail rings than D. negrosensis (21-23 versus 13-16), is known from the eastern Indian Ocean (off NW Australia) and from the Gulf of Thailand and Philippines southeastward to New Guinea and NE Australia in the western Pacific Ocean. Planktonic young of A excisus and early juveniles of D. negrosensis are illustrated and briefly described. , Rhodes University Libraries (Digitisation)

  • Description: The zeid fishes of South Africa are revised; five species in four genera are described and illustrated. 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. Keys to the South African species of Grammicolepididae, Oreosomatidae, and Zeidae are also included. The distributions of zeid fishes are discussed. , Rhodes University Libraries (Digitisation)

  • Description: Pelagic marine fish eggs were collected over a period of 28 months from inshore waters of the Cape of Good Hope. Some 40 species were encountered, of which about 30 were identifiable — either with the aid of published descriptions (particularly those of J. D. F. Gilchrist) or by rearing in the laboratory. Notes are included on the identification of eggs and larvae, duration of the incubation period, spawning season and distribution of the adult, and laboratory rearing. The text is accompanied by 184 figures of eggs, larvae, and juveniles. , Rhodes University Libraries (Digitisation)
