Sri Lanka is an island country with a land area of 65 610 km2. With the declaration of the exclusive economic zone (EEZ) in 1976, the country gained sovereign rights over an ocean area of 536 000 km2 and EEZ extending from 24 to 200 nm. The continental shelf is about 26 000 km2 with an average width of around 22 km, and the coastline is 1 100 km long. The total annual fish production of Sri Lanka was 25 000 t in 1952 and 269 850 t in 1998. Major fish species caught in Sri Lankan waters are skipjack, blood fish, yellow fin tuna, mullet, shark, trevally, Spanish mackerel, prawns, lobsters.
Fisheries are an important source of protein and employment for Sri Lanka’s population. The declaration of the Exclusive Economic Zone (EEZ) in 1976 gave the country a water area larger than its land area. The coastal fisheries resources consist of small and large pelagic fish, demersal and coral reef fish, invertebrates, shrimps and crabs. The small pelagic fish contribute 70% of the catch from coastal waters with an estimated annual production of 152 752 t in 1997.
Reservoir resources and the status of fishery development in India is discussed. The current situation regardingresearch on reservoir ecosystems and fishery resources management is considered, and the ecosystem-oriented strategy for reservoir fisheries development also mentioned.
Coral reefs are recognized as globally important ecosystems, for their fisheries, tourism and biodiversity values in particular, with an estimated annual contribution of $30 billion to the global economy. The benefits that coral reef ecosystems provide through their provisioning, regulating, cultural and supporting services are critical for human wellbeing. The Coral Triangle region (which includes the waters of Indonesia, Malaysia, Papua New Guinea (PNG), the Philippines, Solomon Islands and Timor Leste) supports the highest coral and reef fish species diversity in the world.
In order to achieve sustainable fishing livelihoods in coastal communities, data on profitability of small-scale fisheries relative to fish species caught and gear types used by fishermen is required as part of a broader fisheries management strategy. This study was undertaken with this in mind. Interviews were conducted among 60 fishermen between February and March 2010. Economic assessment of small-scale fishing activities were done using questionnaires based on direct market pricing and contingent valuation methods.
This guide provides a framework for ex-ante evaluation of fisheries and aquaculture projects in developing countries. Ex-ante impact evaluations check the potential of a project or program to deliver benefits from proposed interventions. Providing extensive annotated literature citations, this guide is designed for use by practitioners who may not be fisheries or aquaculture specialists.
An account is given of pelagic fisheries in African lakes and reservoirs. Species introductions are considered, describing also various biological characteristics of the pelagic species. Currently pelagic fisheries are best developed in Lakes Tanganyika, Kariba and Kinneret. Development projects and planning necessary are discussed briefly.
A discussion is presented on the topic of publishing fishery information, indicating the various problems which existin current publishing systems worldwide.
The energy sources of importance in the fishing industry are discussed in detail. An account is given of fish catching,fish growing and fish saving and the role energy plays in each. Wind, sun and biogas are all considered as energy resources.
Early efforts to apply the concept of fisheries co-management in Southeast Asia focused primarily on building the effectiveness of local management institutions and advocating the merits of the approach so that it would be applied in new sites, while gradually learning and adapting to a range of obstacles in practice. Today, with co-management widely embraced by the research community and adopted as policy by an increasing number of governments, a second-generation perspective has emerged.
