Daily amount of rotifers taken by a sea bass Lates calcarifer larvae
(Science and Technology Information Institute, 1990)
The amount of rotifers consumed by a single sea bass Lates calcarifer larva per day (R) was examined by both the direct and by the satiation-digestion methods. In the direct method, R is estimated by the number of rotifers ...
Spontaneous maturation and spawning of milkfish in floating net cages
(Elsevier, 1986)
Milkfish (Chanos chanos Forsskal) reared from wild-caught fry and from hatchery-bred fry matured at 3.5-5.5 years (2.3-4.9 kg). Maturation and spawning of the hatcherybred fish marks the first time the milkfish life-cycle ...
Successive spawning of grouper, Epinephelus suillus (Valenciennes), in a tank and a floating net cage
(Elsevier, 1993)
Wild Epinephelus suillus (Valenciennes) were collected in 1989 to early 1990. To monitor natural spawning in captivity, 6 mature females (3.5–5.0 kg) and 4 mature males (7–12 kg) were transferred to a 4.6×4.6×2 m concrete ...
Effect of season on oocyte development and serum steroid hormones in LHRHa and pimozide-injected catfish Clarias macrocephalus (Günther)
(Japanese Society of Fisheries Science, 1999)
Oocyte and blood samples were taken from gravid female catfish Clarias macrocephalus at 4-h intervals to monitor the stage of oocyte development and serum steroid hormone profiles after injection of luteinizing hormone-releasing ...
Observations on artificial fertilization of eggs and embryonic and larval development of milkfish, Chanos chanos (Forskal)
(Elsevier, 1978)
Hydrated eggs obtained from a female milkfish, Chanos chanos, were artificially fertilized with the milt collected from a male injected with acetone-dried pituitaries of salmon. The fertilized eggs (1.1–1.25 mm in diameter) ...
The effect of stunting on growth, survival, and net production of milkfish (Chanos chanos Forsskal)
(Elsevier, 1988)
The seasonal abundance of milkfish fry in the Philippines has led to the practice of buying a sufficient supply during the peak season to compensate for the shortage during slack periods. Fry that are not immediately grown ...
Acute nitrite toxicity and methemoglobinemia in juvenile milkfish (Chanos chanos Forsskal)
(Elsevier, 1987)
Nitrite was about 55 times more toxic to milkfish juveniles in fresh water than in 16% brackish water: the 48-h median lethal concentrations were 12 mg NO<sub>2-</sub>N/l (95% confidence limit=7.4–19.6) and 675 mg ...
Effects of feeding frequency and amount of feeding on the growth of the grouper, Epinephelus malabaricus
(Science and Technology Information Institute, 1989)
The effects of feeding frequency and amount of food on the growth of juvenile groupers (Epinephelus malabaricus) were investigated for 12 weeks of rearing in net-cages set in an earthen pond. The juveniles (110-130 g in ...
Dietary soy peptide enhances thermotolerance and survival of juvenile japanese flounder, Paralichthys olivaceus
(World Aquaculture Society, 2015)
Soy peptide (SP), a soy protein enzymatic hydrolysate, contains bioactive substances that could be utilized as an immune-stimulating feed ingredient. The experiment evaluated the efficacy of dietary SP on promoting growth, ...
Prospects of host-associated microorganisms in fish and penaeids as probiotics with immunomodulatory functions
(Elsevier, 2015)
Aquatic animals harbor a great number of microorganisms with interesting biological and biochemical diversity. Besides serving as the natural defense system of the host, the utilization potential of this microbial association ...
