(The Japanese Society of Scientific Fisheries, 1979)The egg, larval stages and the first postlarva of the giant tiger prawn, Penaeus monodon Fabricius, reared from egg in the laboratory are described and illustrated. Six naupliar, three protozoeal and three mysis stages ... -
On a new species of Metapenaeus (Crustacea, Decapoda: Penaeidae) from the Philippines
(The Japanese Society of Fisheries Science, 1979)A new species of penaeid prawn, Metapenaeus philippinensis from the Philippines is described in detail and compared with the closely related species, M. ensis. The petasma of the new species which superficially resembles ... -

Larval mycosis in Penaeus monodon
(University of the Philippines, Los Baños, 1979)A phycomycetous fungus, presumably a Lagenidium, was observed to infect Penaeus monodon larvae. Monitoring of the hatchery in 1976 and 1977 showed that it occurred in 35 out of 51 and 22 out of 37 runs, respectively. So ... -
Toxicity of malachite green to the larvae of Penaeus monodon
(University of the Philippines at Los Baños, 1978)The toxicity of malachite green to the larvae of the jumbo tiger prawn Penaeus monodon was determined in a static bioassay. Daily larval death was directly proportional to the chemical concentration of and exposure time ... -
Notes on the courtship and mating behavior in Penaeus monodon Fabricius (Decapoda, Natantia)
(Brill Academic Publishers, 1979)Courtship and mating behavior in the sugpo or giant tiger prawn, Penaeus monodon Fabricius, are described. These are divided into three phases: parallel swimming of male and female; male turns ventral side up to female; ... -
Evaluation of various protein sources for Penaeus monodon postlarvae
(University of the Philippines, Los Baños, 1979)Penaeus monodon postlarvae with an average weight of 15.61 mg each were fed fresh brown mussel meat and artificial diets containing casein, shrimp meal, squid meal and Spirulina as protein sources at a daily rate of 20 per ... -
Observations on artificial fertilization of eggs and embryonic and larval development of milkfish, Chanos chanos (Forskal)
(Elsevier, 1978)Hydrated eggs obtained from a female milkfish, Chanos chanos, were artificially fertilized with the milt collected from a male injected with acetone-dried pituitaries of salmon. The fertilized eggs (1.1–1.25 mm in diameter) ... -
Induced maturation and spawning in five-month-old Penaeus monodon Fabricius by eyestalk ablation
(Elsevier, 1978)Pond-reared sugpo (Penaeus monodon Fabricius) females from coastal fry harvested after 4 months were unilaterally ablated and stocked in an indoor concrete tank with an equal number of males. The first two spawnings were ... -
Notes on the construction of 12 cu m ferrocement tank for prawn broodstock
(International Ferrocement Information Center, 1978)One of the important research studies at the Aquaculture Department of SEAFDEC is the maturation of Penaeus monodon females in captivity. Equal numbers of male and female prawns are stocked in tanks. Ovarian maturation is ... -
Ovarian rematuration of ablated sugpo prawn Penaeus monodon Fabricius
(Institut National de la Recherche Agronomique, 1978)Spent Penaeus monodon females were tagged around one eyestalk with numbered brass tags, stocked in a concrete tank with males, and periodically examined for ovarian rematuration over a six-month period (February to August, ... -
The lancelets [Cephalochordata, Amphioxi] of Lucena Anchorage, Quezon, Philippines
(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 ... -
