Historically, land and water management within many coastal deltas has focused on the exclusion of saline water flows that move upstream from the coast. However, this approach fails to recognize the diversity of rural livelihoods and ecosystems in coastal deltaic areas, the environmental consequences of altering natural saline water flows and the emergence of new activities such as shrimp farming that require brackish water.
Since 1991, the certification, release and maintenance of new species for aquaculture have become part of the national policy in China. During the past 15 years, this policy has been conducted and improved and has begun to show its significant role in Chinese fisheries. This paper describes the updated system of certification, release and maintenance of new species for aquaculture in China.
International organizations are calling for fisheries to be included in a new global deal on climate change. A consortium of 16 organizations including the UN Environment Programme (UNEP), the Food and Agriculture Organization (FAO), the World Bank and the WorldFish Center issued a policy brief to delegates meeting in Bonn from June 1-12 for the latest round of UN climate talks. Their key message was outlined in a Commentary by two of the authors of the brief published May 28 on Nature Reports Climate Change.
This document represents the report and contributed papers from the workshop Pioneering Fish Genetic Resource Management and Seed Dissemination Programmes for Africa: Adapting principles of selective breeding to the improvement of aquaculture in the Volta Basin, convened in Accra, Ghana 27-30 March 2007.
Three studies on pig-duck-fish-azolla integration were conducted simultaneously in La Union, Philippines. Growth performance of pigs and ducks as affected by different levels of azolla meal in their feed, and that of tilapia (Oreochromis niloticus) under varying stocking rates are presented and discussed.
An experiment to rear carp seed was conducted in Tamil Nadu, India during October 2001 to April 2002 as a part of an ambitious programme aimed at standardization of pen fish rearing technology for production of stocking material of desired size at a lower cost. The experiment used six pens erected using locally available materials in the exposed marginal area of an existing reservoir.
Probiotics are widely used in poultry and swine rearing farms but little has been done to incorporate them into aquaculture. This study aimed to pathologically and immunologically evaluate the efficiency of Bacillus subtilis and/or Lactobacillus acidophilus as a potential probiotic in the culture of Nile tilapia (Oreochromis niloticus).
Research into developing farming methods for giant clams at the ICLARM Coastal Aquaculture Centre in the Solomon Islands has proceeded in parallel with a program of village-based trials. This program is an attempt to involve the envisaged recipients of technology at a very early stage. The considerations, design and initial implementation of this program from 1988 to 1990 are described in this article. The expansion, impact and results of the program will be the subject of future publications by the scientists involved.
