Effects of different sex ratios on maturation, fecundity and hatching rates of ablated Penaeus monodon wild stock
(Fisheries Research Society of the Philippines, 1980)
The minimum number of males per female that would still ensure high maturation, fecundity and hatching rates in Penaeus monodon broodstock, is determined. Wild stock P. monodon were stocked in 4 m diameter circular tanks ...
Effect of substrate types on fecundity and nauplii production of ablated Penaeus monodon Fabricius
(Science and Technology Information Institute, Department of Science and Technology, 1980)
The survival, spawning, fecundity, and nauplii production of ablated Penaeus monodon females reared in flow-through broodstock tanks with white coralline and black sand substrates for 62 days, were assessed. Prawns exposed ...
The food and feeding habit of Penaeus monodon Fabricius collected from Makato River, Aklan, Philippines (Decapoda: Natantia)
(E.J. Brill, 1980)
The food of Penaeus monodon Fabricius collected from Makato River, Aklan, consisted mainly of Crustacea (small crabs and shrimps) and molluscs, making up 85% of ingested food. The remaining 15% consisted of fish, polychaetes, ...
Preliminary studies in some aspects of amino acid biosynthesis in juveniles of Penaeus monodon Fabricius: II. Partial purification and characterization of muscle L-glutamate dehydrogenase
(The Philippine Biochemical Society, 1980)
A method of partially purifying L-glutamate dehydrogenase, a key enzyme in the biosynthesis of non-essential amino acids, from the muscle of P. monodon juveniles is presented. Enzyme extraction with Tris-acetate buffer, ...
Acclimation of Penaeus monodon postlarvae to fresh water
(Fisheries Research Society of the Philippines, 1980)
Gradual acclimation of Penaeus monodon Fabricius to fresh water was conducted in glass aquaria and marine plywood tanks over a one-day, two-day, and three-day acclimation periods. Different stages of postlarvae were ...
Studies on the fungal diseases in crustaceans. II. Haliphthoros philippinensis sp. nov. isolated from cultivated larvae of the jumbo tiger prawn (Penaeus monodon)
(Mycological Society of Japan, 1980)
Haliphthoros philippinensis sp. nov., isolated from larvae of P. monodon is described and illustrated as new. The fungus grew at a temperature range of 13.5-36.3 C, with the optimum of 29.3-34.5 C. Growth occurred in ...
Early postmysis stages of the giant tiger prawn, Penaeus monodon Fabricius
(Carcinological Society of Japan, 1980)
The morphological development of the early postmysis stages of the giant tiger prawn, Penaeus monodon are described and illustrated using laboratory-reared specimens and wild ones.
The first 3 or 4 substages are termed ...
Preliminary studies in some aspects of amino acid biosynthesis in juveniles of Penaeus monodon Fabricius: I. Incorporation of 14C from (U-14C) acetate into amino acids to precipitable proteins
(Philippine Biochemical Society, 1980)
Ion-exchange chromatography in conjunction with radioisotope labelling techniques were used to investigate the incorporation of <sup>14</sup>C from (U-<sup>14</sup>C) - acetate into amino acids of precipitable proteins in ...
The effects of feeds and feeding levels on the survival of a prawn, Penaeus monodon larvae
(Kagoshima University Research Center for the South Pacific, 1980)
Penaeus monodon larvae were grown from zoea<sub>1</sub> to mysis<sub>2</sub> stages using varying levels of single-celled Chaetoceros sp., baker's yeast, and a combination of the two. The effects of feeds and feeding on ...
