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 ... -
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−1 was observed within 8 to ... -
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. ... -
Mariculture development and livelihood diversification in the Philippines
(Elsevier, 2012)This paper aims to evaluate mariculture as sustainable livelihood diversification option for coastal fishers in the Philippines and guide policy development in this direction. Mariculture in the Philippines refers to the ... -
Induction of sex change in female Epinephelus coioides by social control
(Society of Israeli Aquaculture and Marine Biotechnology, 1997)Mature female groupers (Epinephelus coioides) of different sizes were stocked in three floating net cages (2 fishes each) and in tanks (2-4 fishes) to induce sex change in the bigger female grouper after isolation from the ... -
Socio-economic impacts of shrimp culture
(Blackwell Publishing, 1997)Farmed shrimp contributed 27% of total world shrimp production in 1995 with a volume of 712 000 tonnes. Undoubtedly, the shrimp culture industry earns valuable foreign exchange for developing countries and generates jobs ... -
Fish predation on mangrove-associated penaeids: The role of structures and substrate
(Elsevier, 1997)The effect of habitat structure and substratum on predation of the greasyback shrimp Metapenaeus ensis (De Haan), white shrimp Penaeus merguiensis De Man and tiger shrimp Penaeus monodon Fabricius by sea bass Lates calcarifer ... -
Low-cost feed for Penaeus monodon reared in tanks and under semi-intensive and intensive conditions in brackishwater ponds
(Elsevier, 1997)Experimental diets for juvenile Penaeus monodon were formulated incorporating inexpensive indigenous raw materials. Local fish meal and cowpea meal were tested as replacements for imported protein sources and the diets did ... -
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 ... -
Resistance of rainbow trout Oncorhynchus mykiss to infectious hematopoietic necrosis virus (IHNV) experimental infection following ingestion of natural and synthetic carotenoids
(Elsevier, 2012)Further to previous studies showing modulation of innate immune responses by dietary carotenoids, an experiment was conducted to examine the resistance to a viral pathogen in rainbow trout after oral ingestion of synthetic ... -
Polyculture of milkfish Chanos chanos (Forsskal) and the red seaweed Gracilariopsis bailinae (Zhang et Xia) in brackish water earthen ponds
(Wiley-Blackwell, 2004)Growth, net production, and survival rates of milkfish cultured with Gracilariopsis bailinae at two stocking density combinations (T1– 30 fingerlings 100-m−2 pond+1-kg G. bailinae 4-m−2 net ... -
Notes on the induced spawning, embryonic and larval development of the window-pane shell, Placuna placenta (Linnaeus, 1758), in the laboratory
(Elsevier, 1997)Intragonadal injection of 0.5 ml of a 2-mM serotonin solution or seawater irradiated by ultraviolet (UV) light (925–1395 mW h/l) induced spawning in male and female window-pane shell, Placuna placenta (Linnaeus, 1758). ... -
Developmental trends in the mouthparts during growth from juvenile to adult of the tropical freshwater crayfish, Cherax quadricarinatus von Martens, 1868 (Decapoda: Parastacidae)
(International Society of Invertebrate Reproduction and Development, 1997)The structure and setal armature of the mouthparts of Cherax quadricarinatus during development from juvenile to adult were examined using light and scanning electron microscopy. Significant general transformations include ... -
Effect of salinity on survival of Metapenaeus anchistus juveniles and subadults
(University of the Philippines in the Visayas, 1997)Survival of Metapenaeus anchistus (De Man) juveniles and subadults at 5, 15, 25, 35 (control) and 45 ppt salinity levels was determined and compared. Salinity levels lower than 35 ppt level were prepared by diluting pure ... -
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 ... -
Growth rate, yield and economics of Gracilariopsis bailinae (Gracilariales, Rhodophyta) using fixed bottom long-line method
(Science and Technology Information Institute, 1997)Vegetative thalli of Gracilariopsis bailinae weighing 10 g each were tied to a 5-m monofilament line with plastic strips and laid horizontally on the substrate and were observed to grow at 30 d interval for 9 months. The ... -
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, ... -
