Culture experiments on the copepod, Tisbintra elongata MORI, and evaluation of that species as food organism for milkfish larvae S Yamasaki & J Canto Jr. -
SEAFDEC Aquaculture Department Quarterly Research Report, 1979 - Aquaculture Department, Southeast Asian Fisheries Development CenterFive types of food were used to culture T. elongata: rice bran, cow dung, bread, cow dung, bread yeast, fermented fish solubles and Spirulina. Bread yeast was found to give the highest densities. An evaluation was also made of the effectivity of rice bran and fermented fish solubles for the outdoor mass culture of T. elongata . A comparative study on the growth and survival rate of milkfish fry (Chanos chanos) fed with T. elongata and Artemia showed there to be no significant differences between the diets.
Culture experiments on the harpacticoid copepod, Tisbintra elongata Mori, and evaluation of that species as a food organism for milkfish larvae S Yamasaki & JT Canto Jr. -
Memoirs of Faculty of Fisheries Kagoshima University, 1980 - Faculty of Fisheries, Kagoshima UniversityThe mass culture of the harpacticoid copepod, Tisbintra elongata, indigenous to Panay Island were conducted, feeding them on several kinds of food materials. Salinity tolerance as physiological parameter was also examined. At the same time their efficiency as food for milkfish larvae was evaluated. The highest density of 10.5 individuals/m/ was obtained in copepods fed on rice bran and fermented fish solubles at rates of 0.125 to 0.25 and 0.16 mg/indiv./day respectively. The provision of shelter as habitat was also supplementary for growth. This species of copepod was found to be euryhaline, and could grow to high densities in waters hypersaline to their natural habitat. Statistically, no significant difference of growth was observed between the milkfish larvae fed on this species and Artemia nauplius. However, comparatively stable results were obtained using Tisbintra as food. In this rearing of milkfish larvae, those larvae whose sizewas 12.3 to 13.5mm in body length were considered to be just prior to morphological change.
