Investment prospects in the production of the common carp (Cyprinus carpio) fingerlings in freshwater ponds

Since the introduction of Common carp Cyprinus carpio in Oyo State (Nigeria) from Israel in 1964, various local breeding methods have been employed in carp rearing to improve the survival rate at all stages of development during breeding. The physico-chemical parameters of the ponds which were simultaneously investigated for carp rearing in this study includes temperature (t), dissolved oxygen (DO) and hydrogen-ion concentration (pH). However, high rates of water displacement in the breeding ponds were unfavourable to the development of zooplankton which play important role in the food web of C. carpio. The survival rates of 15.88-69.50% and 19.60-33.83% obtained for the egg-hatchling and hatchling-fingerling stages respectively were encouraging. A breeding performance of this magnitude was found to be viable, breaking even in the fourth year. However, an increase in size of this trial project would be more profitable and increase fingerling supply as well as provide employment opportunities. This study thereby provides some baseline information on some local techniques and progress in the propagation of C. carpio and scope for further improvement

GHERS: Greater Harvest and Economic Returns from Shrimp: Final program performance report

The Greater Harvest and Economic Returns from Shrimp (GHERS) is an initiative of Poverty Reduction by Increasing the Competitiveness of Enterprises (PRICE) project, funded by USAID. The objective of GHERS was to increase the productive capacity of existing farms and enhance quality of shrimp delivered to processors adding over $ 45 million to current sales, $10 million new investment and 14,000 new jobs. This final performance report presents the activities and achievements of the project since 2008.

Performance in managing marine resources in the Bay of Bengal
