Aquaculture In Dagupan City, Philippines, Michael A. Rice, Arthur Z. Devera

Michael A Rice

The development of aquaculture in the Agno-Pantal-Calmay River Estuary system of Dagupan City, Pangasinan Province in the Philippines is reviewed. Traditionally, extensive pond culture of milkfish, Chanos chanos and penaeid shrimp was practiced along with culture of mangrove oysters, Crassostrea iredalei, in adjacent estuarine waterways. Netpen culture of serranid groupers in the estuaries began in the early 1980s, followed by intensive fish pen culture of milkfish in the late 1980s. Over intensification of finfish aquaculture led to hyper eutrophication and fish kills beginning in 1996. Official governmental response to the fish kills is reported, and recommendations to prevent future fish …

Growth And Reproductive Performance Of Small Ruminants Under Integrated Livestock Oil Palm Production System, Ahmad Salihin Hj Baba, Azillah A., Mukherjee T. K., Abdullah R. B.

Ahmad Salihin Hj Baba

The effects of supplementation with mixed fodder or concentrate were investigated on the performance of a) growth of male lambs;md kids grazing extensively under oil palm trees and b) reproduction of ewes and goats stall-fed with native herbage. Supplemented kids and lambs had higher average daily weight gain than controls but the effect was only significant for those which received concentrate (p < 0.05). Final body weight was only significantly different from controls for lambs supplemented with concentrate (p < 0.05). The ages at puberty, first mating, first conception and first kidding of supplemented goats were about 110 days earlier than those for controls (p < 0.05 or better). Supplemented goats had first mating and conceived at lower body weights (p < 0.01) than those in control groups. Different feeding regimes had no effects (p > 0.05) on the reproductive performance of ewes apart fi om highest body weight of first lambing in animals supplemented with concentrate (p < 0.05). Native herbage available under oil palm trees of 5 years old was sufficient for growth …
