Seasonal variation in food and feeding of Penaeus monodon Fabricius (Decapoda, Natantia)
(E.J. Brill, 1982)
A preliminary study on feeding habits of P. monodon F. (cf. Marte, 1980) indicated seasonal variations in feeding in this species. Similar observations have been reported for P. aztecus Ives and P. duorarum Burkenroad. The ...
An improved method for collecting naturally spawned milkfish eggs from floating cages
(Elsevier, 1988)
Natural spawnings of captive milkfish (Chanos chanos Forsskal) held in floating cages were observed in 1980, 1981, 1983 and 1985. Frequency of spawnings increased from two in 1980 to 41 in 1985. Various collectors and ...
Natural spawning, egg and fry production of milkfish, Chanos chanos (Forsskal), broodstock reared in concrete tanks
(Blackwell Publishing, 1994)
Gonadal maturation, rematuration, and spawning of nine- (1982 stock) and ten-year-old (1981 stock) milkfish reared in 150 and 200 m<sup>3</sup> concrete tanks were observed in 1990 and 1991. From 23 September to 9 November ...
The use of a Visual Implant tag to monitor the reproductive performance of individual milkfish Chanos chanos Forsskal
(Blackwell Publishing, 1992)
Nine-year old milkfish (3.8 kg., average body weight) were individually marked with Visible Implant (VI) tags to monitor their reproductive performance following hormonal induction. All tags were retained after one year; ...
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, ...
Gonadotropin profiles in serum of milkfish treated with salmon pituitary homogenate
(University of the Philippines Los Baños, 1983)
Serum gonadotropin (GtH) levels were determined by radioimmunoassay (RIA) in adult regressed milkfish injected or implanted with various doses of salmon pituitary homogenate (SPH). Gonadotropin profiles of injected or ...

(Elsevier, 1985)
Captive Lates calcarifer broodstock at Tigbauan, Iloilo (Philippines) were implanted with cholesterol-based pellets of the LHRH analogue D-Trp<sup>6</sup>-desGly<sup>10</sup>-LHRH ethylamide or D-hArg(Et<sub>2</sub>)<sup>6</sup>, ...
Broodstock management and egg production of milkfish, Chanos chanos Forsskal
(Blackwell Publishing, 1993)
The milkfish, Chanos chanos Forsskal, industry in the Philippines suffers from a limited supply of wild fry. The demand for milkfish fry has spurred research in artificial propagation to supplement the natural seed supply. ...
A collecting gear for naturally-spawned milkfish (Chanos chanos Forsskal) eggs in circular floating net cages
(Elsevier, 1988)
A collecting gear for naturally-spawned milkfish (Chanos chanos Forsskal) eggs in circular floating net cages is described. The gear has been shown to be effective in collecting large numbers of eggs. The collecting gear ...
Induced gonadal maturation and rematuration in milkfish: Limited success with chronic administration of testosterone and gonadotropin-releasing hormone analogues (GnRH-A)
(Elsevier, 1988)
Nine experiments were conducted to investigate the influence of chronic administration of testosterone (T) and gonadotropin-releasing hormone (GnRH) analogues on first maturation of 4- to 6-year-old fish and rematuration ...
