Monosex culture of the mud crab Scylla serrata at three stocking densities with Gracilaria as crab shelter
(Australian Centre for International Agricultural Research, 1999)
The effects of three levels of stocking density (0.5, 1.5 or 3.0/m2) and monosex culture (male or female) on the growth, survival and production of Scylla serrata were investigated. Juvenile crabs were stocked in 150 m2 ...
LHRHa and pimozide-induced breeding in the catfish, Clarias macrocephalus (Gunther).
(1994)
Clarias macrocephalus is endemaic yet dwinding freshwater foodfish in the Philippines. Induced breeding protocol was developed after a series of studies which determined the appropriate egg size, proper time of stripping ...

Studies on the nursery rearing of seabass, Lates calcarifer (Bloch) fry in illuminated floating net cages
(Ministry of Agriculture and Water; King Abdulaziz City for Science and Technology; Riyadh Chamber of Commerce and Industry, 1994)
The feasibility of rearing seabass, Lates calcarifer, fry for fingerling production in illuminated floating nursery cages was determined. In experiment 1, seabass fry of 20.0 mm mean TL were stocked at 600 and 1200 in 1 ...
Occurrence of aberrant spermatids in the freshwater sculpin, Cottus nozawae Snyder
(Asian Fisheries Society, 1994)
Light and electron microscopic investigation were conducted on the spermatogenic cell in the testis of the freshwater sculpin, Cottus nozawae. Light microscopic examination showed that two types of spermatids, normal and ...
A statistical procedure for using "reference fish" to compare the growth of genetic strains in aquaculture
(Asian Fisheries Society, 1990)
No simple, well-accepted procedures exist for comparing the relative performance of genetic strains of fish in aquaculture environments. The major technical problem is providing adequate statistical replication of ponds ...
Fisheries biology of milkfish (Chanos chanos Forskal)

Milkfish (Chanos chanos Forskal) is one of the most important food fish species in the world. In Indonesia, Taiwan and the Philippines, more than a quarter of a million tonnes of milkfish are harvested annually in brackish ...
Heterogeneity in Philippine milkfish populations
(Asian Fisheries Society, 1990)
Twelve milkfish (Chanos chanos ) populations from 6 coastal areas in the Philippines, collected at the fry stage and reared until fingerling size, were analysed for electrophoretic variation at 28 presumptive loci. Seven ...
Acute toxicity of mercury to Oreochromis niloticus fingerlings
(SEAMEO BIOTROP, 1991)
Fingerlings of Oreochromis niloticus were exposed to the following mercury (as HgCl<sub>2</sub>) concentrations: 0.005, 0.01, 0.02, 0.03, 0.04, 0.05 and 0.06 mg l<sup>-1</sup> Hg of water. Hyperactivity and erratic swimming ...
Shrimp health research in the Asia-Pacific: present status and future directives
(Food and Agriculture Organization of the United Nations, 1996)
Shrimp harvests from intensive aquaculture have recently declined in areas which have been productive for many years. Because the most convenient, although not necessarily factual, explanation for these crop failures has ...
