Threonine requirement of juvenile marine shrimp Penaeus monodon
(Elsevier, 1997)
The threonine requirement was determined for juvenile marine shrimp. Penaeus monodon postlarvae, PL20, were stocked in 30-1 fiberglass tanks at ten shrimp per tank arranged in a completely randomized design with six ...
Morphological abnormalities in hatchery-bred milkfish (Chanos chanos Forsskal) fry and juveniles
(Elsevier, 1997)
Morphological abnormality has been observed in hatchery-bred milkfish juveniles. To characterize and quantify the occurrence of these anomalies, hatchery-bred milkfish juveniles from commercial nursery ponds were sampled, ...
Semi-mass culture of the dinoflagellate Gymnodinium splendens as a live food source for the initial feeding of marine finfish larvae
(Springer Verlag, 1997)
A technique was developed for the semi-mass culture of the unarmored dinoflagellate, Gymnodinium splendens under laboratory conditions. A maximum cell density of 4600 to 6800 cells ml<sup>−1</sup> was observed within 8 to ...
Growth and reproductive performance of the Asian catfish Clarias macrocephalus (Gunther) fed artificial diets
(Blackwell Publishing, 1997)
Four natural ingredient diets similar in nutrient composition (crude protein = 42–44%; P/E ratio = 115–120 mg/kcal) but different in protein sources, were formulated and fed to hatchery-reared catfish to measure the relative ...
Influence of pyrite oxidation and soil acidification on some essential nutrient elements.
(Aquacultural Engineering Society (AES), 1997)
Influence of soil acidification on some essential nutrient elements was observed experimentally during periodic leaching at 10-day intervals of pyritic soil materials. Pyritic soil in glass columns saturated with distilled ...
Laboratory manipulation of Gracilariopsis bailinae Zhang et Xia (Gracilariales, Rhodophyta)
(Walter de Gruyter, 1997)
Carpospore germination, carposporeling development and tetraspore formation were investigated in Gracilariopsis bailinae Zhang et Xia by manipulating photoperiod, photon flux density, temperature, salinity and nutrients. ...
Larval rearing of the grouper Epinephelus suillus under laboratory conditions
(Elsevier, 1997)
A protocol for rearing orange-spotted rockcod, Epinephelus suillus in the hatchery is described. The feeding regime consisted of Chlorella, Brachionus, Artemia and minced fish. With this regime, survival rates at Day 24 ...
Testicular histology and serum steroid hormone profiles in hatchery-bred catfish Clarias macrocephalus (Gunther) during an annual reproductive cycle
(Japanese Society of Fisheries Science, 1997)
Testicular development, gonadosomatic index (GSI), and related steroid hormones (testosterone or T, 11-ketotestosterone or 11-KT, 17α, 20β-dihydroxy-4-pregnen-3-one or DHP) in serum were monitored during an annual reproductive ...
The interactive effect of some environmental factors on the growth, agar yield and quality of Gracilariopsis bailinae (Zhang et Xia) cultured in tanks
(Walter de Gruyter, 1997)
The single and interactive effects of light and temperature, salinity, and urea enrichment on the growth and agar yield and quality of Gracilariopsis bailinae were determined under indoor and outdoor tank conditions. Culture ...
World wide aquaculture drug and vaccine registration progress
(European Association of Fish Pathologists, 1997)
Harmonisation of the most important standards and guidelines required in each country. A start has been shown to be made in developing an international effort toward aquaculture drug approvals and vaccine licensure and ...
