Evaluating the management effectiveness of three marine protected areas in the Calamianes Islands, Palawan Province, Philippines: Process, selected results and their implications for planning and management

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.

Echinoderms piggybacking on sea cucumbers: Benign effects on sediment turnover and movement of hosts

Sea cucumbers (Holothuroidea) are known to host ectocommensal animals but echinoderm epibionts have never been reported nor their effects on hosts appraised quantitatively. At one location in New Caledonia, we found a high number of ophiuroids (Ophiothela cf. danae) and synaptid sea cucumbers (Synaptula media and Synaptula sp.) living on the bumpy external body wall of sea cucumbers, Stichopus herrmanni.

Community management as part of the inland capture fisheries strategy in Bangladesh

Bangladesh has had comprehensive experience of community based management for inland capture fisheries from several projects (revenue and externally funded) over the last 10 to 15 years. The lessons were extensively used for the elaboration of a strategy and a programme, which will seek to consolidate gains in and expansion of community based management linked to institutional and legal reform and a recognition and strengthening of the roles of civil society and the private sector. The Ministry of Fisheries and Livestock adopted the National Fisheries Strategy in January 2006.

Coastal resources management, policy and planning in Bangladesh

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.

Use and exchange of aquatic genetic resources for food and aquaculture: clarias catfish

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.

A survey of ichthyofauna of Lake Kanyaboli and other small waterbodies in Kenya: alternative refugia for endangered fish species.

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.

Snake prices and crocodile appetites: aquatic wildlife supply and demand on Tonle Sap Lake, Cambodia

Commercial trade is a major driver of over-exploitation of wild species, but the pattern of demand and how it responds to changes in supply is poorly understood. Here we explore the markets for snakes from Tonle Sap Lake in Cambodia to evaluate future exploitation scenarios, identify entry points for conservation and, more generally, to illustrate the value of multi-scale analysis of markets to traded wildlife conservation. In Cambodia, the largest driver of snake exploitation is the domestic trade in snakes as crocodile food.

Scophthalmus Rafinesque, 1810: The valid generic name for the turbot, S. maximus (Linnaeus, 1758) [Pleuronectiformes: Scophthalmidae]

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.

Reproductive and trophic ecology of an assemblage of aquatic and semi-aquatic snakes in Tonle Sap, Cambodia

We studied the reproductive and trophic ecology of a group of aquatic and semi-aquatic snakes that face severe hunting pressure in Cambodia. Over a two-year period we sampled hunters' catches, measuring and dissecting a total of 8982 specimens of seven snake species, five of which belong to the family Homalopsidae. The seven species—Enhydris enhydris, Enhydris longicauda, Homalopsis buccata, Enhydris bocourti, Erpeton tentaculatus, Xenochrophis piscator, and Cylindrophis ruffus—all inhabit Tonle Sap Lake, the largest lake in South-East Asia.

Manutention après capture des produits halieutiques de faible valeur et menaces pour la qualité nutritionnelle: une étude des pratiques dans la région du Lac Victoria

L’objectif de la présente étude est d’examiner les pratiques courantes en matière de transformation, de conservation et d’entreposage des produits halieutiques de faible valeur commercialisés dans la région du Lac Victoria et l’impact de ces pratiques sur la qualité nutritionnelle de ces produits et leur contribution aux populations menacées de malnutrition et aux Personnes Vivant avec le VIH/SIDA (PVV).
