Growth regulation by insulin-like growth factor-I in fish
(Japan Society for Bioscience, Biotechnology, and Agrochemistry, 2000)
Insulin-like growth factor-I (IGF-I) is a mitogenic polypeptide that plays an essential role in the regulation of development and somatic growth of vertebrates, mainly by mediating growth hormone actions. It has clearly ...
Measures of egg quality in induced spawns of the Asian sea bass, Lates calcarifer Bloch
(Springer Verlag, 2000)
The egg morphometry and lipid and protein components were determined in induced spawns (n = 14) of the sea bass, Lates calcarifer, to identify measures of egg quality. Based on fertilization and hatching rates, the spawns ...
GABA, 5-HT and amino acids in the rotifers Brachionus plicatilis and Brachionus rotundiformis
(Elsevier, 2000)
γ-Aminobutyric acid (GABA) and 5-hydroxytryptamine (5-HT) have been shown to increase the reproduction of the Brachionus plicatilis (NH3L strain). In the present study, the endogenous presence of GABA and 5-HT in the ...
Effect of juvenile hormone and serotonin (5-HT) on mixis induction of the rotifer Brachionus plicatilis Muller
(Elsevier, 2000)
Juvenile hormone (JH) and serotonin (5-HT) were previously shown to enhance mictic (sexual) female production of the rotifer Brachionus plicatilis in batch cultures. To explore the basis of these effects, experiments were ...
Why are Halophytophthora species well adapted to mangrove habitats?
(Springer Verlag, 2000)
Halophytophthora species are commonly isolated from fallen mangrove leaves from early to late stages of decay. In this study we show that these organisms are well adpted to mangrove habitats as they have a wide tolerance ...
Community fishery resources management on Malalison Island, Philippines: R & D framework, interventions, and policy implications
(Taylor & Francis, 2000)
In 1991, the Aquaculture Department of the Southeast Asian Fisheries Development Center launched a community-based fishery resources management project on Malalison Island, in central Philippines, to help conserve the ...
Growth, agar yield and quality of selected agarophyte species from the Philippines
(Walter de Gruyter, 2000)
Three local agarophyte species (Gracilaria firma, Gracilaria sp. and Gracilariopsis bailinae) were grown under controlled outdoor flow-through culture conditions. Growth rates and agar characteristics of the three species ...
Feeding ecology of silverperch, Terapon plumbeus Kner, and the impact fish-pens in Laguna de Bay, Philippines
(Blackwell Publishing, 2000)
Aquaculture is an important factor in the fishery of Laguna de Bay in the Philippines; fish-pens and net-cages covered ≈10% of the lake surface in the late 1990s. The present study was carried out to assess the possible ...
Processed meat solubles, protamino aqua, used as an ingredient in juvenile shrimp feeds
(Society of Israeli Aquaculture and Marine Biotechnology, 2000)
The nutritive value of processed meat solubles, Protamino Aqua, a by-product from slaughter-houses, was examined in a growth trial with juvenile tiger shrimp Penaeus monodon. Experimental diets were formulated to contain ...
Transport of Scylla serrata megalopae at various densities and durations
(Elsevier, 2000)
The optimal conditions for transport of Scylla serrata megalopae were determined. Loading densities of 50, 100 and 150 ind l<sup>−1</sup> of hatchery-reared megalopae were studied over a 6-h simulated transport, including ...
