Vertical rope cultivation of Gracilaria (Rhodophyta) using vegetative fragments
(Walter de Gruyter, 1990)
Preliminary field culture of Gracilaria using vegetative fragments inserted between braids of ropes suspended vertically inside a floating cage was undertaken to assess the daily growth rate and monthly yield as influenced ...
Effects of antioxidants on feed quality and growth of Penaeus monodon juveniles
(Wiley-Blackwell, 1992)
Four practical diets were formulated to contain 0.05%, of the following antioxidants: butylated hydroxytoluene (BHT), butylated hydroxy anisole (BHA), propyl gallate (PG) or ethoxyquin (ETHQ). A fifth diet, with no added ...
Thyroxine injection of female rabbitfish (Siganus guttatus) broodstock: changes in thyroid hormone levels in plasma, eggs, and yolk-sac larvae, and its effect on larval growth and survival
(Elsevier, 1993)
The thyroid hormone levels in female rabbitfish, Siganus guttatus, plasma, eggs, and yolk-sac larvae were measured before and after thyroxine (T<sub>4</sub>) injection in female spawners at doses of 1, 10, and 100 μg ...
Effect of dietary fatty acids on growth of milkfish Chanos chanos fry in brackish water
(Elsevier, 1996)
Five purified microbound diets containing 1% of 18:2n − 6, 18:3n − 3, 20:4n − 6, or n − 3 highly unsaturated fatty acids (HUFA: 60% 20:5n − 3 + 40% 22:6n − 3) in addition to 8% 18:1n − 9, and a control diet containing 9% ...
Effects of low nitrogen-phosphorus ratios in the phytoplankton community in Laguna de Bay, a shallow eutrophic lake in the Philippines
(Springer Verlag, 2004)
The effects of low nitrogen-phosphorus ratios on microalgae from a large eutrophic freshwater lake in the Philippines were investigated. Natural microalgal populations from Laguna de Bay, the largest lake in the Philippines, ...
Cell growth, effect of filtrate and nutritive value of the tropical Prasinophyte Tetraselmis tetrathele (Butcher) at different phases of culture
(Blackwell Publishing, 2005)
A local algal isolate Tetraselmis tetrathele was studied to determine the suitable levels of three growth factors (nutrient medium, light intensity and photoperiod) for mass culture. Significantly higher population cell ...
Field efficacy evaluation of a formalin-inactivated white spot syndrome virus (WSSV) vaccine for the preventive management of WSSV infection in shrimp grow-out ponds
(Elsevier, 2021)
A shrimp grow-out trial was conducted in four 700 m<sup>2</sup> earthen ponds in Dumangas Brackishwater Station of SEAFDEC Aquaculture Department, in Iloilo, Philippines to evaluate the efficacy of a combination of immersion- ...
Interaction effect of light intensity and photoperiod on egg hatchability, survival and growth of polychaete Marphysa iloiloensis from larva to juvenile
(Elsevier, 2021)
Polychaetes are of high commercial interest as potential feed in aquaculture industry. Despite this, knowledge of polychaete culture is limited. The goal of this study is to develop a protocol that maximizes survival and ...
Growth performance, production and economic viability of Indian white shrimp (Penaeus indicus H. Milne Edwards) fed with varying dietary protein levels
(Wiley, 2022-03)
The growth efficiency, productivity and economic viability of Indian white shrimp (<i>Penaeus indicus</i>) fed with diet containing 40% (CP<sub>high</sub>) and 34% (CP<sub>low</sub>) crude protein (CP) levels were determined ...
Effects of feeding rate and sediment depth on the survival, growth performance, and biomass of mud polychaete Marphysa iloiloensis from early juvenile to adult in grow-out tanks
(Elsevier, 2022-02-15)
Polychaete aquaculture has progressed in some countries to meet the high demand of fish bait and aquaculture industries. However, knowledge on the aquaculture requirements of polychaetes in the grow-out is still scarce. ...
