Artificial incubation for intensive fry production of Nile tilapia Oreochromis niloticus (L.)
Share
Abstract
Two experiments were conducted to evaluate and compare the production, quality, and survival of eggs and the subsequent growth and survival of fry in two small scale production systems: (i) natural incubation (NI), and (ii) egg collection followed by artificial incubation in upwelling glass funnels (AI). Cost benefits analysis was applied to the production figures to compare the economic viability of the two methods. The results were used to design a fry production system for the intensive production of Genetically Male Tilapia (GMT) from limited numbers of novel YY-male broodstock.

CRM in the Philippines: Lessons learned
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1996)Philippine coastal communities can become capable fishery resource managers and that their management practices can become largely self-sustaining if the project approach focuses on assisting fishermen to learn how to help themselves. Community organization is an essential part of the process and should not be viewed as an end product in itself. There are also no quick fixes, and projects require a complex array of activities if large numbers of coastal residents are to be assisted. In some of these projects, the control of illegal fishing combined with limiting of commercial fishing to offshore areas and good coastal habitat management resulted in a doubling of daily fish catch and income for small-scale fishermen. However, even with the best of management, the total fishery harvest is limited and further increases in individual fishing income can only come from reducing total fishing effort. This will require a system of control on access to the resource to limit the number and kind of fishing gears and to divide the resource equitably. Assisting coastal communities to devise and implement realistic equitable access controls is the major challenge facing coastal resource co-management.
