A survey was conducted in Regions 1 (Ilocos), 3 (Central Luzon), 6 (Western Visayas) and 7 (Central Visayas) of the Philippines between 20 May and 25 July 2002. Questionnaires were distributed and interviews were performed during the study to establish the trends in cultivation management after the ...

The effects of size of Manila clam Ruditapes philippinarum on the predation rate, foraging time budget, encounter behavior and shell-breaking techniques of swimming crab Portunus trituberculatus were studied by video recording analysis system in the laboratory. Here, we report the differences...

The current culture systems, speices cultured, hatchery location, support groups and sustainable potentials of aquaculture in Mindanao (second largest of the three major slands in the Philippines) were presented.

The three high-value extractive species, Eucheuma denticulatum, Perna viridis and Crassotrea Eucheuma denticulatum, Perna viridis and Crassotrea sp, have been integrated into the existing commercial finfish culture of Chanos chanos and Trachinotus blochii in the Carcar Bay, Eastern Cebu,...

To examine the variation of multiple predator effects and functional response caused by interaction of conspecific predators under different prey density, we established swimming crab, Portunus trituberculatus - Manila clam, Ruditapes philippinarum foraging systems in the laboratory. Specifically,...

Interactions between multiple predators, whether conspecific or interspecific, has been the subject of many researches. There is a shortage of studies investigating how different size classes of a single species interact with one another to generate multiple predator effects. Here, we used a...

The apple snail, Pomacea canaliculata, an alien invasive species that causes considerable damage to rice culture, is now being used as an alternative protein source in small-scale aquaculture in the Philippines. Interviews with selected fish farmers rearing Japanese koi and Macrobrachium...

Oyster farming is an important industry both in developed and developing countries. The high demand for oysters has caused overexploitation of natural stocks. This led to dwindling spat fall and unstable production. This study was conducted to compare growth and survival of wild and hatchery-bred...

Suspended culture of bivalves offers a number of advantages over beach (intertidal) culture, but is often hindered by two issues: biofouling and suboptimal shell shape. This study assessed the efficacy of two novel culture media in Pacific oyster (Crassostrea gigas) grow-out and Manila clam (...

This technical paper provides a comprehensive review of on-farm feeding and feed management practices in aquaculture. It comprises of (a) ten case studies on feeding and feed management practices carried out in seven selected countries of Asia and Africa for eight species that belong to four major...
