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 ...
Effect of tagging on maturation and survival of ablated Penaeus monodon in painted and unpainted tanks
(San Carlos Publications, University of San Carlos, 1989)
A study was conducted to determine the effects of tags and tank color on reproductive performance and survival of pond-reared Penaeus monodon after eyestalk ablation. In 1986, the best over-all reproductive performance was ...
An evaluation of three annelids as feed ingredients in formulated diets for juvenile Penaeus monodon
(Fisheries Research Society of the Philippines, 1985)
The nutritive value of two species of earthworms, Eisenia foetida and Eudrilus euginae and the marine annelid, Nereis sp. in P. monodon juvenila diets was determined in two separate experiments. Percentage weight gain and ...
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, ...
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 ...
