An overview of environmental issues in developing-country aquaculture.

Aquaculture, like all interventions by humans to exploit or manage natural resources for food production, has the potential for causing environmental harm as well as for improving livelihood and nutrition. Aquaculture development must be undertaken in a broad intersectoral context, considering especially its interactions with agriculture, forestry and capture fisheries and its environmental consequences.

Low abundances and diversities of benthic faunas of shallow, coastal sediments in the Solomon Islands and their implications for assessing environmental impacts of logging

The diversity and abundance of benthic organisms were examined in relation to logging impacts in Western Province, Solomon Islands. Organisms occupying sediments offshore from the mouths of logged and unlogged streams in two areas were sampled at three depths during a single survey. Overall abundances of organisms were low, and patterns varied between areas.

Integrated agriculture-aquaculture: a way for food security for small farmers and better resource management and environment

Traditionally fish have been a natural component of rice-ecosystems. Intensive agriculture has led to degradation offish habitats, resulting in disappearance of fish from rice fields. The economic viability and impact on the environment of integrating aquaculture with agriculture during rainfed and irrigated rice growing seasons were studied in 256 farms in Bangladesh. Farmers on an average obtained fish production of 230 and 214 kg ha-1 during irrigated and rainfed seasons, respectively.

Nairobi declaration: conservation of aquatic biodiversity and use of genetically improved and alien species for aquaculture in Africa

An Expert Consultation on Biosafety and Environmental Impact of Genetic Enhancement and Introduction of Improved Tilapia strains/ Alien species in Africa, was convened in Nairobi, Kenya from 20-23 February 2002 to discuss and develop guidelines that will foster the development of aquaculture while maintaining biodiversity. The meeting was attended by aquaculturists, geneticists and conservation specialists from Africa and from international organizations.

Environmental impact of the golden snail (Pomacea sp.) on rice farming systems in the Philippines.

A summary report of the workshop held at the Freshwater Aquaculture Center, Central Luzon State University, Nueva Ecija, Philippines, on 9-10 November 1989. It discusses the effects wrought by the golden snail since its introduction to the Philippines, particularly on rice farming systems. Ways to control the snail are presented.

Environment and aquaculture in developing countries: summary report of the Bellagio Conference on Environment and Aquaculture in Developing Countries, 17-22 September 1990, Bellagio, Italy.

Recommendations from the 1990 international conference on environment and aquaculture in developing countries.

Environment and aquaculture in developing countries.

Contains 15 reviews on the environmental impact of aquaculture including inland and coastal ecosystems, integration of agriculture and aquaculture, shrimp culture, antibiotics and other trace environmental contaminants, toxic algal blooms, socioeconomic aspects and regional overviews for Africa, Asia and Latin America. These are also transcripts of discussions on these topics, with recommendations and a framework for decisionmaking when considering the environmental impact of aquaculture development.
