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 ...
Developmental and ecological stages in the life history of milkfish Chanos chanos (F.)
(Fisheries Research Society of the Philippines, 1981)
Seven stages in the life history of milkfish Chanos chanos are suggested: embryonic, yolksac larval, larval, postlarval, juvenile, sub-adult and adult stages. These were based on morphological differences and on their ...
Evaluation of the high rate algae pond system for softdrink waste treatment and for fish culture.
(Asean Journals Ltd., 1987)
The High Rate Algae Pond System (HRAP) as secondary treatment for Cola effluents showed potential for reducing both COD load (about 88%) and high pH level (down to pH 7.0 -8.0). The effluent quality improved and can be ...
Limnological notes on the finfish production problem of Laguna de Bay.
(College of Arts and Sciences, University of the Philippines, 1988)
Environmental problems have significantly affected fishery production and management in Laguna de Bay, the largest lake in the Philippines. Fishermen and fishpen operators are complaining about the slow growth of fish and ...
Maturation and spawning of Penaeus indicus using different ablation methods
(Elsevier, 1987)
Wild immature Penaeus indicus females (11.5 ± 3.1 g body weight) were ablated by pinching, cautery or tying of one eyestalk, and stocked with control (unablated) females and males (9.2 ± 1.5 g) in a 12-m<sup>3</sup> ...
Carbohydrate, nitrogen and protein content of kinetin-treated Azolla pinnata var. imbricata plants.
(College of Arts and Sciences, University of the Philippines, 1988)
The influence of various levels of kinetin on growth, carbohydrate, nitrogen, and protein content of Azolla pinnata var. imbricata plants cultured in a nitrogen-free 40% Hoagland’s solution under greenhouse conditions was ...
Induced spawning of maturing milkfish (Chanos chanos) using human chorionic gonadotropin and mammalian and salmon gonadotropin releasing hormone analogues
(Elsevier, 1988)
The response of maturing female milkfish to D-Ala<sup>6</sup>-des Gly<sup>10</sup> mammalian GnRH ethylamide (mGnRH-A), D-Arg<sup>6</sup>-des Gly<sup>10</sup> salmon GnRH ethylamide (sGnRH-A) and human chorionic gonadotropin ...
Sodium-EDTA effects on survival and metamorphosis of Penaeus monodon larvae
(Elsevier, 1988)
The effects of Na-EDTA on growth and survival of Penaeus monodon larvae were determined for applications given daily or every 3 days. Application of 2.0, 5.0, and 10.0 ppm were given on day 1, day 4 and day 7 in Experiment ...
A new device for recording the feeding activity of milkfish
(The Japanese Society of Scientific Fisheries, 1981)
Knowledge on the feeding activity is basic and very important for rearing fish. The information on the feeding activity rhythm of the animal suggests the proper time to feed it. Many devices have been designed to record ...
Identification and characterization of vitellin in a hermaphrodite shrimp, Pandalus kessleri
(Elsevier, 1989)
1. A female specific protein (FSP, vitellogenin) in hemolymph and its related ovarian protein (vitellin) of Pandalus kessleri were studied by means of electrophoretical and immunological procedures.
2. The vitellin was ...
