(University of the Philippines at Los Baños, 1978)Two species of lancelets (amphioxi) are described from Philippine waters: Branchiostoma belcheri and Epigonichthys cultellus. The characters suited for numerical evaluation in both species were examined statistically. ... -
Successful spawning of cultured Penaeus monodon Fabricius after eyestalk ablation
(Elsevier, 1977)Preliminary experiments resulted in successful spawning of captive stock of the prawn Penaeus monodon, or “sugpo”, to complete the life cycle and produce a viable F1 generation of larvae. Gonadal development was induced ... -
Effects of furanace on zoeae and mysis of Penaeus monodon.
(University of the Philippines at Los Baños, 1977)The toxicity of the chemotherapeutant Furanace on Z2 and M1 of the jumbo tiger prawn Penaeus monodon was assayed for a period of 24 hr. The LD50 for Z2 was 1.6 mg per liter; for ... -
Culture of Artemia on rice bran: The conversion of a waste-product into highly nutritive animal protein
(Elsevier, 1980)The age-old problem of finding a cheap suitable food for Artemia is finally solved with rice bran, in fact a waste-product which is available at a very low price in many countries all over the world. -
Practical techniques for mapping small patches of mangroves
(Springer, 2010)Practical mapping methods employing GPS field surveys and manual image analyses with affordable software were used to assess two mangrove sites in Aklan Province, NE Panay Island, central Philippines. The Jawili mangroves, ... -
Economic assessment of commercial hatchery production of milkfish (Chanos chanos Forsskal) fry
(John Wiley and Sons, 1999)The economic viabilities of two types of commercial hatchery milkfish (Chanos chanos) fry operations were assessed and compared. Based on the actual cost of input, the physical facilities, and the potential production ... -
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 ... -
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 ... -
Survival and growth of bighead carp fry exposed to low salinities
(Kluwer, 1999)Bighead carp (Aristichthys nobilis Oshima) fry of various ages (11, 18, and 35 days post-hatch) were exposed to the low salinities encountered during the annual intrusion of seawater in Laguna Lake, Philippines. Practical ... -
Seminal plasma composition, sperm motility, and milt dilution in the Asian catfish Clarias macrocephalus (Gunther)
(Elsevier, 1999)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
(Elsevier, 1999)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 ... -
Test of size-specific mass selection for Nile tilapia, Oreochromis niloticus L., cage farming in the Philippines
(John Wiley and Sons, 1999)One generation of mass selection based on the collimation procedure (early culling of large fry) was applied on Nile tilapia, Oreochromis niloticus L., in net cages set in Laguna de Bay, Philippines. The objective was to ... -
Growth, maturity and induced spawning of mangrove red snapper, Lutjanus argentimaculatus, broodstock reared in concrete tanks
(Society of Israeli Aquaculture and Marine Biotechnology, 1999)Mangrove red snapper, Lutjanus argentimaculatus, fry (n=30) were collected in 1993 and reared in concrete tanks. They were fed trash fish every other day initially at 10% to 5%, until they reached three years. They reached ... -
Isolation and cDNA cloning of somatolactin in rabbitfish (Siganus guttatus).
(Academic Press, 1999)We report the isolation and cDNA cloning of somatolactin (SL) from rabbitfish, Siganus guttatus. Rabbitfish SL was isolated from an alkaline extract of the pituitary glands by gel filtration chromatography on Sephadex G-100 ... -
Growth and production of deformed and nondeformed hatchery-bred milkfish (Chanos chanos) in brackishwater ponds
(Society of Israeli Aquaculture and Marine Biotechnology, 1999)This study evaluated the growth and survival of morphologically deformed and nondeformed hatchery-bred milkfish in brackishwater ponds. It compared the size-frequency distribution of the nondeformed fish with the deformed ... -
Mangroves, fishponds, and the quest for sustainability
(American Association for the Advancement of Science, 2005)Aquaculture, the farming of shrimp and other useful aquatic and marine plants and animals in artificially confined and tended ponds, pens, and cages, ranks as a phenomenal success story in global food production. In 1975, ... -
Dietary vitamin C and E supplementation and reproduction of milkfish Chanos chanos Forsskal
