Studies on the causative organism of Oreochromis niloticus (Linnaeus) fry mortalities I. Primary isolation and pathogenicity experiments.
(Taylor & Francis, 1987)
Oreochromis niloticus fry reared in 50 L aquaria at a density of 1,000 fry manifested mortalities of 15% daily. Afflicted two-week old fry exhibited darker pigmentation, emaciation lesions, and surface swimming. Parasites ...
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 ...
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 ...
Induced spawning of maturing milkfish (Chanos chanos Forsskal) with gonadotropin-releasing hormone (GnRH) analogues administered in various ways
(Elsevier, 1987)
The response of mature female captive milkfish to mammalian and salmon gonadotropin-releasing hormone analogues (mGnRH-A and sGnRH-A) was investigated. Prior to spawning, six groups of three females received (1) 10–16 μg ...
Amino acid requirements for growth of Nile tilapia
(American Society for Nutrition, 1988)
A series of feeding experiments was conducted in aquaria to determine the quantitative requirements of the 10 essential amino acids for growth of young Nile tilapia (Oreochromis niloticus). The test diets contained casein ...
The effect of thyroxine on the larvae and fry of Sarotherodon niloticus L. (Tilapia nilotica)
(Elsevier, 1983)
Effects of thyroxine (T<sub>4</sub>) (0.1 ppm; 0.3 ppm; 0.5 ppm) on Sarotherodon niloticus L. yolk sac larvae were studied after 4 weeks of treatment from hatching. T<sub>4</sub> at 0.5 ppm accelerated yolk resorption but ...
Effect of artificial diets on growth and survival of milkfish fry in fresh water
(Elsevier, 1983)
Wild milkfish fry (mean weight = 15 mg) were reared in fresh water for 5 weeks using four artificial dry diets, Moina, or blended water hyacinth leaves as feed. The fry fed with artificial diets attained 83–95% mean survival ...
