The article discusses the guidelines for environmentally acceptable aquaculture to ensure that financial gain is not at the expense of the ecosystem or the rest of society. The general principles, strategies and objectives, and action plans for the implementation of environment-friendly aquaculture is also discussed.

Cage culture of sea bass in Malaysia

The article discusses the cage culture practice of sea bass (Lates calcarifer) in Malaysia. Problems on feed and seed supply and overcrowding are also discussed. Despite these problems, seabass cage culture still continuously booms.

Impact of seafarming: fish farms vs. mussel farms

The article presents comparative impacts of fish and mussel seafarms. Specifically, it tackles the impacts of the two farms on the following: solid waste production, water flow and sedimentation, effect on native bottom fauna, effect on wild fish populations, the spread of toxic chemicals and drugs, and multi-use conflicts.

A continuing PROCESS: for grassroots development

PROCESS (Participatory Research, Organization of Communities, and Education Towards Struggle for Self-reliance) is the offshoot of an experiment encouraged by the International Labor Organization to stimulate self-help initiatives among rural communities in Antique and Batangas. Its operations today extend to 10 provinces in the Philippines, touching the lives of thousands of farmers, fisherfolk, women and other marginalized sectors.

To borrow or not to borrow? The small fry's money problem

The money problem of the small fishfarmers is where to run to for much needed funds. In the Philippines, small-scale fisherfolk have traditionally relied on informal lenders in the absence of personal funds and access to bank credit.

Strategies for sustainable use of living aquatic resources

Recommendations of the Department of Environment and Natural Resources (Philippines) to conserve biodiversity, maintain the integrity of the environment, protect fishery stocks, involve fishing communities in the management, and use environment-friendly technologies for enhancing fishery production.

Notes on the larval rearing scheme at SEAFDEC/AQD

For tiger shrimp, milkfish, and sea bass, larval rearing starts with the hatching of artificially spawned eggs. The eggs are stocked in larval rearing tanks, hatched, and metamorphosed larvae are fed and reared with good water management. Fry are harvested after about 30 days.

Technology for the community: SEAFDEC-designed artificial reefs

An account is given of the fabrication and deployment of artificial reefs used in the SEAFDEC/AQD's Community Fishery Resource Management project, which focused on Malalison Island located in west Central Philippines. The project aimed to apply community-based techniques of fishery resource management through the collaboration of community organizations, biologists and social scientists. The 3 types of reefs (building blocks, concrete pipe culvert, and modified concrete pipe culvert) were deployed at Gui-ob reef covering an area of less than 1 ha.

La pêche aux poissons volants

Flying fish is an important fishery resource in most of the Southeast Asian countries like Vietnam where artisanal fishing methods are applied. This study deals with an investigation on the Touran fishing area. In this region, fishing operations have never been studied neither in Vietnam nor in neighboring countries. The survey of fishing grounds was conducted by Mr. Nguyen-Chua, and data was collected by Tran-văn-Tri.

Ichthyological ecoregions of Argentina

The Argentine Republic is situated in the southernmost portion of the American continent, occupying over 2,785,600 km2 not including the Antarctic territory. The country ranges from subtropical areas (21º46’S) to subantarctic regions (55º03’S), extending latitudinally over about 4,000 km. It possesses significant latitudinal and altitudinal variation (33º of latitudinal range, and heights from Bajo de San Julián in Santa Cruz province at 105 m below sea level, up to Mt. Aconcagua, 6,959 m over sea level), as well as two gradients of physical variability, extending in north-south and east-west directions. Owing to these features, the country presents a wide range of climates and soil types, being one of the countries with greatest diversity of biogeographical units (Lean et al., 1990, In: Bertonatti & Corcuera, 2000). There are four main hydrographic systems: Río de la Plata basin, the Atlantic and Pacific drainages, and several endorrheic systems. Within these basins, the ichthyofaunistic assemblage is well represented, with different magnitude in accordance with the different taxonomic groupings and regions considered. From an ichthyogeographic standpoint, and according to the works of Ringuelet (1975) and Arratia et al. (1983), Argentina is included in the Brasilic and Austral Subregions. The first of these is represented by two domains: the Andean Domain, comprising the southernmost portion of Titicaca Province, and the Paranensean Domain, including part of Alto Paraná and Paranoplatensean Provinces. The Austral Subregion is represented in Argentina by the Subandean-Cuyan and Patagonian Provinces. The present survey indicates that there are about 441 fish species in Argentina, distributed throughout the country; this number represents less than 10% of the total fish species occurring in the Neotropical Region. There is a recognizable trend of faunal impoverishment, both in North-South and East-West direction, reaching its maximum expression in the provinces of Tierra del Fuego (situated at approximately 52º30’S to 55ºS, and 65ºS to 68º50’W) and San Juan (approximately 28º50’S and 67ºW to 70º45’W), which have 4 and 5 fish species respectively. In north-south direction, one of the regional indicators of this phenomenon is the Salado river basin in Buenos Aires province, which constitutes the southern distributional boundary for the majority of the paranoplatensean ichthyofauna; 12 of the families occurring in the Paraná-Plata system are absent from this pauperized paranensean ichthyofaunal assemblage. Most of the continental fish fauna of Argentina belongs to the primary division of Myers (1949), while some elements are included in the secondary division and others in an amphibiotic or ‘marine penetration’ category. This ichthyofaunistic scope encompasses a wide range of morphological, biological, ecological and ethological types (benthic and pelagic, migrating and sedentary, haematophagous or parasites, annual species, inhabitants of plains or heights, estivation-adapted, etc.) inhabiting different regions within the national territory.
