“…GiH-netting showed that individuals of all 13 marine species were often abundant in the deeper offshore waters of the Bot Estuary at a size in excess Lasiak (1983b) mately 2-4 months after spawning and at lengths usually less than 25 rom (Table V). The fish then remain in the estuaries until winter before returning to sea.…”

“…Juvenile mullet, in particular Liza dumerili and Liza richarrisoni, are extremely abundant in East Cape estuaries (Beckley 1983a(Beckley , 1984a) and van der Horst & Erasmus (1981) and Lasiak (1983) have concluded that these two species spawn in the inshore marine environment. The extremely low numbers of Pomadasys olivaceum and mullet larvae captured in the nearshore region indicates that the larvae probably develop away from the coast and only migrate inshore to nursery habitats as post-larvae capable of swimming.…”

The nearshore ichthyoplankton of Algoa Bay was sampled at six stations over a two-year period between 1980 and 1982. Larvae of 26 families of teleosts were identified with Gobiidae constituting 48,0%, Engraulidae 26,7% and Clupeidae 12,1% of all larvae sampled. Caffrogobius spp., Engraulis capensis and Etrumeus teres were the dominant species. Representatives of families such as Sparidae and Mugilidae which numerically dominate juvenile nursery areas in Algoa Bay were not abundant in the nearshore ichthyoplankton. The various taxa occurring in the ichthyoplankton are discussed in terms of distribution of adults and juveniles, breeding biology and available information on early life history. The paucity of larvae of coastal species with pelagic eggs is highlighted and, with reference to the findings of other workers and local oceanographic conditions, a possible spawning strategy is suggested.S. Afr. J. Zool. 1986, 21: 244 -252 Die igtioplankton van Algoabaai is by ses stasies langs die kus vanaf 1980 tot 1982 gemonster. Larwes van 26 families van Teleostei is ge"identifiseer en, van die aantal larwes wat gevang is, het Gobiidae 48,0%, Engraulidae 26,7% en Clupeidae 12,1% van die totaal uitgemaak. Caffrogobius spp., Engraulis capensis en Etrumeus teres was die oorheersende spesies. Verteenwoordigers van families soos Sparidae en Mugilidae, wat numeries die jongviskweekgebiede in Algoabaai oorheers, was nie volop in die igtioplankton nie. Die verskillende spesies van vislarwes wat in die igtioplankton verteenwoordig is, word in terme van die verspreiding van volwassenes en kleintjies, die teelbiologie en die beskikbare inligting oor vroee lewensloop bespreek. Die skaarsheid van larwes van kusspesies met pelagiese eiers het duidelik geword en met verwysing na plaaslike oseanografiese toestande word 'n moontlike kuitskietpatroon voorgestel.

“…In the months of October, November, January and March there was a predominance of females (Figure 3). The sex ratio could be affected by various factors related to fishery, season of the year, shoals in the feeding and spawning areas (Sarojini, 1957;Silva and Silva, 1981;Lasiak, 1982). Spawning habitats of female ballyhoo H. brasiliensis and balao (H. balao) in south Florida were described by McBrige and Thurman (2003).…”

The gonad development and reproductive aspects of Hemiramphus brasiliensis from the coastal waters of Rio Grande do Norte, Brazil were verified. This paper presents data on the length-weight relationship, sex ratio, length at first sexual maturity, gonad development, reproductive period and fecundity of H. brasiliensis. Females of this species predominated in the sampled population and were larger in size than the males. The length at the first sexual maturation of males was 20.8 cm and that of females was 21.5 cm. The macroscopic characteristics of the gonads indicated four maturation stages. Histological studies of gonads of H. brasiliensis showed six phases of oocyte development and four phases of spermatocyte development. The batch fecundity of this species is 1153 (±258.22) oocytes for 50 g body weight of female. The microscopic characteristics of gonad development indicate that H. brasiliensis is a multiple spawner, with active reproductive period during the months of January to June and October. The reproductive period of this species is independent of the rainy period of the region.Keywords: sex ratio, histology of gonads, fecundity, reproductive period.
