Evaluating the management effectiveness of marine protected areas (MPAs) has been a continuing challenge in marine conservation in the tropics. This paper describes the process involved, the chosen indicators and the selected results of the evaluation of management effectiveness of three MPAs in the Calamianes Islands, Palawan Province, Philippines. The evaluation was a participatory process that involved several institutions: academe, an externally-funded project, local governments, national government agencies and research organizations.
In this paper we describe the construction of an online GIS database system, hosted by WorldFish, which stores bio-physical, ecological and socio-economic data for the ‘Coral Triangle Area’ in South-east Asia and the Pacific. The database has been built in partnership with all six (Timor-Leste, Malaysia, Indonesia, The Philippines, Solomon Islands and Papua New Guinea) of the Coral Triangle countries, and represents a valuable source of information for natural resource managers at the regional scale.
Cambodia's wetlands cover over 30 percent of the country’s land area and support one of the largest, most diverse and intensive freshwater fisheries in the world. In the flood season (July-February), the flood waters from the Mekong River and Tonle Sap Lake catchments create a vast open water system on Cambodia’s lowlands. During this period, inundated rice fields become open access fishing grounds for local villagers and migrant fishers.
This paper reviews the coastal fishery resources of Bangladesh emphasizing the coastal environment, capture fisheries and management issues relative to the sector. Bangladesh’s Exclusive Economic Zone (EEZ) covers an area of about 166 000 km2. This area has abundant natural resources such as fish, shrimps, crabs and other marine products. Shrimp and fish trawling is the most important economic activity in this area. The fishery sector makes a significant contribution to the national economy in terms of foreign exchange, income generation and employment.
Nearshore marine resources play a significant role in the lives of South Pacific islanders and can be critical to the economies of nations in the region. However, few countries have adequate management controls in place to ensure harvests remain at sustainable levels, and so determining current levels of utilization is far from easy. A lack of information about the volume of both domestic and international trade in marine invertebrates in high demand is a growing concern.
There are 58 species of Clarias recognized in FishBase (as of January 2009), 33 in Africa and 25 in Asia. Aquaculture of clariids is important with 30 countries reporting a total production of over 300 000 t worth nearly US$400 million in 2006. Most production involves the African Clarias gariepinus (Burchell, 1822) and three Asian species, Clarias batrachus (Linnaeus, 1758), Clarias macrocephalus (Günther, 1864) and Clarias fuscus (Lacep'de, 1803). In much of Asia, hybrids of introduced C.
In 1988, the World Conservation Union (WCU) Red Book of Endangered Species listed hundreds of endemic fishes of Lake Victoria under a single heading - "ENDANGERED". Most of the endemic native food fishes are either endangered or extinct. However, a survey of the fauna of Lake Kanyaboli, revealed that a few remaining samples of these native fishes are actually thriving. These include several unidentified Haplochromis spp., Oreochromis esculentus and Oreochromis variabilis.
In the past 50 years, the turbot is referred to either as Scophthalmus maximus (Linnaeus, 1758) or Psetta maxima (Linnaeus, 1758) in the literature. Norman (1931) had argued that the valid name for the turbot was Scophthalmus maximus. However, his recommendation was never universally accepted, and today the confusing situation exists where two generic names are still being used for this species. We address this issue by analysing findings from recently published works on the anatomy, molecular and morphological phylogenetic systematics, and ecology of scophthalmid fishes.
Barbus paludinosus and Barbus trimaculatus were sampled in Lake Chilwa and the Mnembo River mouth between February 2004 and January 2005, using nets equivalent to those used commercially, to analyse their reproductive biology and distribution as a basis for recommending sustainable fisheries management and conservation practices.
The 1997 International Year of the Reef sees the release of ReefBase 2.0: a global database on coral reefs and their resources. It provides the most comprehensive and accessible repository of information to date. Containing information on over 7000 coral reefs in more than 123 countries, ReefBase 2.0 offers an extensive range of time-related data pertaining to coastal tourism, benthic environment ecology, fish population statistics, oceanography, socioeconomics, mariculture, and harvest activities. It also outlines the stresses causing reef degradation as well as management initiatives.
