The skull of milkfish, Chanos chanos Forsskal
(Japanese Society of Systematic Zoology, 1980)
The skull of the milkfish, C. chanos, is described so that it may be used as a tool in identifying the effect of artificial propagation in terms of skeletal malformations.
Impact of fishpond management on the mangrove ecosystem in the Philippines
(Natural Resources Management Center and National Mangrove Committee, Ministry of Natural Resources, 1986)
Fishpond development in the Philippines is discussed, examining resulting impacts on the mangrove ecosystems. Socio-economical implications and management measures are also considered.
Milkfish nutrition: a review
(Philippine Council for Aquatic and Marine Research and Development, 1989)
This paper reviews recent work on milkfish nutrition. Substantial progress had been made towards understanding the digestive physiology of milkfish. Major enzaymes envolved in the digestions of carbohydrates, protein and ...
Amino acid and fatty acid profiles in aquaculture nutrition studies
(Asian Fisheries Society, 1989)
The amino acid profile is an important parameter in the evaluation of protein quality and in requirement studies. Amino acid profiles are usually determined in 2 steps: hydrolysis of the protein to constituent amino acids ...
Maturation and induced spawning of the mangrove red snapper (Lutjanus argentimaculatus) reared in a floating net cage in the Philippines
(International Center for Living Aquatic Resources Management (ICLARM), 1996)
Wild-caught mangrove red snapper (Lutjanus argentimaculatus) were reared in a floating net cage at SEAFDEC/AQD's Igang Marine Substation at Guimaras Island, Central Philippines. In 1993, monthly samplings and induced ...
Effect of season on oocyte development and serum steroid hormones in LHRHa and pimozide-injected catfish Clarias macrocephalus (Günther)
(Japanese Society of Fisheries Science, 1999)
Oocyte and blood samples were taken from gravid female catfish Clarias macrocephalus at 4-h intervals to monitor the stage of oocyte development and serum steroid hormone profiles after injection of luteinizing hormone-releasing ...
Sulphur amino acid requirement of juvenile Asian sea bass Lates calcarifer
(John Wiley and Sons, 1999)
The dietary requirement of juvenile Asian sea bass Lates calcarifer for total sulphur amino acids was studied. Fish (average initial weight of 2.59 plus or minus 0.08 g) were reared in twelve 500 L fibreglass tanks provided ...
Seminal plasma composition, sperm motility, and milt dilution in the Asian catfish Clarias macrocephalus (Gunther)
Ionic composition of the seminal plasma and factors that initiate sperm motility in the freshwater Asian catfish Clarias macrocephalus, were examined to develop an artificial seminal plasma (ASP) that can be used to dilute ...
Growth of five Asian red tilapia strains in saline environments
Growth of five Asian red tilapia strains (BFS, NIFI, FAC, PF and HL) were evaluated in brackish and seawater. Eight-week-old juveniles from the five test strains were size-matched with similarly aged Oreochromis mossambicus ...
Year-round spawning and seed production of the rabbitfish, Siganus guttatus
A series of experiments on the spawning and larval rearing of Siganus guttatus was conducted during a 14-month period in 1984–1985. Spawning occurred every month throughout the year, without hormonal treatment, between the ...
