Breeding and rearing of sand goby (Oxyeleotris marmoratus Blk.) fry

Abstract

A large-scale experiment on production of sand goby fry was conducted for one annual cycle at Nong-Sua Fisheries Station in Thailand. Approximately 1000 egg nests containing 25 million eggs were collected from January through October from artificial substrates. The hatching rate of fertilized eggs was approximately 80%. Fry were reared in two stages. In stage 1, the newly developed fry, with average total body length of 4 mm and mouth size opening of approx. 0.1 mm, were first fed with a combination of chicken-egg slurry and live rotifers. The survival rate for this stage ranged from 7 to 55%, with an average of 20% among batches of egg nests collected during the year. Older stage 2 fry were fed with live Moina sp., chironomid larvae, and ground raw fish from days 30 to 60. Stage 2 survival rates ranged from 60 to 99% and length increased from 2.4 to 3.8 cm. Growth rate was inversely related to stocking density at this stage. A total of 147 300 juvenile fish was produced in the l-year effort.

The Utilization of Soybean Meal in Formulated Diet for Marble Goby, Oxyeleotris marmoratus

“…It is a delicacy lean fish with excellent meat texture and has a lucrative market in the Asian region (Sreevatana, 1993;Masagca & Sumantadinata, 1994;Sverdrup-Jensen, 2002). In Malaysia, since the early 1980's this fish had attracted the attention of aquaculturist to produce seedling for aquaculture production (Tan & Lam, 1973;Tavarutmaneegul & Lin, 1988;Cheah et al, 1994;Senoo et al, 1994). Although mass production of marble goby is yet established; the attractive market price and high demand make it a great potential species for aquaculture production.…”

Larval description of the sympatric species, Craterocephalus stercusmuscarum stercusmuscarum(Pisces: Atherinidae) and Mogurnda adspersa(Pisces: Eleotridae) from tropical streams of north‐east Queensland, Australia

“…Historically, M. adspersa was widely distributed within Australia, occurring throughout the Murray‐Darling drainage and south‐eastern regions of Australia and extending north to the Wet Tropics region of north‐eastern Queensland (Merrick & Schmida, 1984). Studies on the early ontogeny of eleotriid species are mostly restricted to species of Hypseleotris Gill, including Hypseleotris compressa (Kreft), Hypseleotris galii (Ogilby)(Auty, 1978; Merrick & Schmida, 1984) and Hypseleotris klunzingeri (Ogilby)(Lake, 1967; Anderson et al ., 1971; Auty, 1978) and one other species, Oxyeleotris marmoratus Bleeker (Tan & Lam, 1973; Tavarutmaneegul & Kwei Lin, 1988; Senoo et al ., 1994, 1997). Anecdotal descriptions of the early ontogeny are available for M. adspersa (Llewellyn, 1971; Merrick & Schmida, 1984), Philypnodon grandiceps (Krefft)(Llewellyn, 1971) and Oxyeleotris lineolatus (Steindachner)(B. Herbert, pers.…”

Advances in the Culture of Rotifers for use in Rearing Marine Ornamental Fish

“…The same feeding regimen, however, has been found to be inappropriate for the larvae of some marine fish (e.g., gobies, angels, groupers, rabbitfish, surgeon fish), where the major constraint apparently is the small size of the newly hatched larvae and corresponding small mouth gape (Tavarutmaneegul and Lim 1988;Cheah et al 1994;Tamaru et al 1995;2000a;Doi et al 1997). Recently, research activities in Hawaii have delivered promising results in the larval rearing of the marine angelfish (TenBruggencate 2002), which indicate that the identification of initial food item(s) that will result in larval survival of species that have been difficult to propagate will soon be forthcoming.…”
