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 ...
Comparison of the silo and broadcast methods of applying organic fertilizer in milkfish, Chanos chanos (Forsskal), ponds
(Elsevier, 1988)
The efficacy of the silo and broadcast methods of applying organic fertilizers in ponds for the production of pond-floor, microbenthic biological complex, a natural food source known as lablab, was tested in 1-ha ponds, ...
Artificial diets for milkfish, Chanos chanos (Forsskal), fry reared in seawater
(Elsevier, 1988)
Milkfish fry obtained from the wild (0.009 g body weight, 10 mm total length) were stocked at 200 individuals in each of 18 fiberglass tanks containing 30 l of filtered aerated seawater. Mean salinity and temperature were ...
Transition from endogenous to exogenous nutrition sources in larval rabbitfish Siganus guttatus
(Japanese Society of Fisheries Science, 1988)
The early larval development of Siganus guttatus was studied with emphasis on the transition from endogenous to exogenous feeding. Three rearing trials were conducted as follows: 1) rearing in a 5 ton concrete tank at ...
Uptake and elimination of iodine-131 by the freshwater clam Corbicula manilensis Philippi from water
(College of Arts and Sciences, University of the Philippines, 1988)
Whole body uptake of Iodine-131 by the freshwater clam, Corbicula manilensis, from contaminated water was followed using NaI scintillation counter. The bioaccumulation factor (BF) exclusive of shell was 5.44. The degree ...
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 ...
Cage culture of Oreochromis aureus and Oreochromis niloticus hybrids in Laguna Lake, Philippines
(Taylor & Francis, 1988)
A reciprocal cross of male Oreochromis aureus and female Oreochromis niloticus were made to produce the hybrids stocked in cages in Laguna Lake, Philippines with and without feeding. The growth rates of the hybrids from ...
The effect of dietary protein-energy levels on growth and metabolism of milkfish (Chanos chanos Forsskal)
(Elsevier, 1988)
<ol><li>Groups of milkfish juveniles (mean weight, 2.8 g) were fed diets containing white fishmeal and gelatin with varying protein-energy to total metabolizable energy (PE:TME) ratios.</li><li>Amino acids were incorporated ...
Critical factors influencing survival and hatching of milkfish (Chanos chanos Forsskal) eggs during simulated transport
(Elsevier, 1988)
The effects of loading density, length of transit time, temperature and salinity on milkfish (Chanos chanos Forsskal) eggs during simulated transport were examined. Rocking motion approximating conditions of transport of ...
Sustained hormone release. III. Use of gonadotropin releasing hormone analogues to induce multiple spawnings in sea bass, Lates calcarifer
(Elsevier, 1988)
Two gonadotropin releasing hormone analogues (GnRHa), [D-Ala<sup>6</sup>, Pro<sup>9</sup>-ethylamide] mammalian GnRH and [D-Arg<sup>6</sup>, Pro<sup>9</sup>-ethylamide] salmon GnRH, were shown to induce spawning in see ...
