Serum steroid hormones, reproductive and larval performance of the Asian catfish Clarias macrocephalus (Gunther) during the off- and peak reproductive seasons
(Institute of Zoology, Academia Sinica, Taipei, Taiwan, R.O.C., 2001)
Serum samples were taken from gravid female catfish 0 to 24 h after injection of luteinizing hormone releasing hormone analogue (LHRHa) and pimozide (PIM) to monitor the serum steroid hormone levels during the off seasons ...
Illuminated-cage nursery of the Asian sea bass, Lates calcarifer Bloch, (Centropomidae): effects of initial body size and stocking density
(Asian Fisheries Society; World Aquaculture Society - Southeast Asian Chapter, 2000)
This study was conducted to determine the appropriate initial body size and the corresponding stocking density of sea bass, Lates calcarifer, during nursery rearing in illuminated cages. Hatchery-produced sea bass fry of ...
Growth and external reproductive parameters in pond-reared Penaeus monodon
(Marine Science Institute, University of the Philippines, 1994)
Pond-reared Penaeus monodon males and females were sampled regularly over a 4 month period of length and weight measurments to the body and external reproductive organs; joining of the petasmata and the presence of sperm ...
Induction of sex inversion in juvenile grouper, Epinephelus malabaricus, (Bloch and Schneider) by bi-weekly injections of 17 alpha-methyltestosterone
(Society for the Study of Endocrinology, Metabolism and Reproduction, University of Hong Kong, 1989)
Groupers (Family Serranidae) are protogynous hermaphrodites. Natural sex inversion of different species occurs at 2-11 years of age . The scarcity of wild mature males and the length of time to change sex underline the ...

Evaluation of different live food organisms on growth and survival of river catfish, Mystus nemurus (C&V) larvae
(European Aquaculture Society, 2001)
Mystus nemurus is one of the most commercially important freshwater fish in Malaysia. Even though artificial breeding or reproduction of M. nemurus is done in private hatcheries around Peninsular Malaysia, inadequate seed ...
Food consumption of seaperch, Lates calcarifer, in captivity.
(Pudoc, 1989)
In the Philppines, feeds and constitutes some 70% of the total capital cost in aquacultural, which illustrates the central ipmortance of such inputs and at the same time justifies a major research effort to study the field ...
Institutional capacity development for sustainable aquaculture and fisheries: Strategic partnership with local institutions
(Terrapub, 2008)
Many people living in the rural areas in the Philippines, as in other developing countries in Southeast Asia, depend on aquatic resources for their food and livelihood. For the past two decades, the Aquaculture Department ...
Culture and screening of food organisms as potential larval food for finfish and shellfish
(South China Sea Fisheries Development and Coordinating Programme, 1982)
The culture of food organisms for fin and shellfish larvae is discussed in detail. Some of the artificial and enriched media that have been developed and tested for microalgae culture are enumerated and some isolation ...
Recent developments in design and management of small-scale hatchery for Penaeus monodon in the Philippines
(South China Sea Fisheries Development and Coordinating Programme, 1982)
It is a common belief that the zoea of Penaeus monodon are completely filter feeders. Thus, diatoms like chaetoceros and phytoflagellates are maintained at high feeding densities as much as 80 000 cells/ml in hatchery tanks ...
Effects of furanace on the development of larval stages of Penaeus monodon Fabricius
(Sea Grant College Program, Texas A&M University, 1979)
Successful molts and morphological defects in P. monodon zoeae (Z<sub>1</sub>, Z<sub>2</sub>, Z<sub>3</sub>) resulting from a 24-h exposure to 1.0 and 2.0 mg/L furanace in baths of 1.0 and 2.0 mg/L were quantified. Molting ...
