The climate and eastern ocean systems project

A brief description of the NMFS/ORSTOM/ILCARM climate and Eastern Ocean systems (CEOS) project is given. CEOS will study the four major eastern boundary current regions (Peru/Chile, California, Northwest and Southwest Africa) and attempt to separate local short term changes of their resources and/or dynamics from long-term, climatic global changes. Expected products range from a large, widely accessible oceanographic / atmospheric database to various documents that will present key results as well as improved contacts and stronger analytical capabilities in cooperating national institutions.

Stock evaluation and development of a breeding program for common carp (Cyprinus carpio) in Karnataka, India: progress of a research project

Common carp (Cyprinus carpio) is the single most important species for aquaculture in the state of Karnataka, India, where it is generally grown in polyculture with Indian major carps. Precocious maturation and unwanted reproduction in the species have been identified as constraints to increase production in aquaculture and culture-based fisheries in Karnataka state. Stocks of C. carpio obtained from Hungary (Amur and P3), Indonesia (Rajdanu) and Vietnam (SV) are being assessed alongside two local stocks (L-BRP and L-FRS) in a series of culture performance trials with the objective of setting up a base population for selective breeding. The paper presents progress of research being undertaken at the Fisheries Research Station, University of Agricultural Sciences, Bangalore, India.

Ongoing rehabilitation of coastal communities in Aceh province : a new project

This article presents an overview of the project on Rehabilitation of Fisheries and Aquaculture in Tsunami-affected Coastal Communities in Aceh Province. Building on the research results from the recently completed projects detailed in the previous articles, this project shall synthesize information on coastal fishing communities and resources in order to develop site-specific management options to support rehabilitation of fisheries and aquaculture.

The autobiographical project of Soveida Dosamantes in Face of an angel, by Denise Chávez

O objetivo desta dissertação é investigar o viés coletivo da autobiografia ficcional de Face of an angel, da escritora estadunidense e de origem mexicana Denise Chávez. Desse modo, o trabalho pretende discutir a sociedade chicana descrita sob a ótica da narradora/protagonista, Soveida Dosamantes, investigando desde o processo histórico de que é resultado, passando pela iniquidade entre os papéis desempenhados por homens e mulheres até chegar ao discurso autorreferencial com que a narradora/protagonista representa o ambiente cultural em que se insere. Antes da narrativa propriamente dita, há a árvore genealógica da narradora/protagonista, assinalando que o que vai se descortinar ao longo da leitura é uma saga de família. Assim, Soveida Dosamantes utiliza a sua ambiência doméstica, bem como a comunidade da fictícia cidade de Água Oscura, sua cidade natal, como recorte de uma estrutura social maior. Fazendo uso do discurso autobiográfico, a narradora/protagonista criada por Denise Chávez expõe as mazelas de uma comunidade que, em virtude ser produto do colonialismo e do neocolonialismo, perdeu sua identidade cultural. Em Face of an angel, através do relato em primeira pessoa de sua narradora/protagonista, a autora Denise Chávez reproduz o universo em que nasceu e cresceu. Cedendo a Soveida Dosamantes componentes autobiográficos como complicadas relações familiares, personagens femininas nativas que funcionam como sentinelas de práticas ancestrais que o domínio europeu apagou, personagens masculinos que mascaram sua fragilidade por trás de uma força e de um poder aparentes, Chávez representa em Face of an Angel o microcosmos de uma comunidade que vem, aos poucos, subvertendo o discurso oficial e conquistando o seu terreno no panorama político e social estadunidense

From drawing board to dining table: the success story of the GIFT project

As compared to crops and livestock, the genetic enhancement of fish is in its infancy. While significant progress has been achieved in the genetic improvement of temperate fish such as salmonids, no efforts were made until the late 1980s for the genetic improvement of tropical finfish, which account for about 90 percent of global aquaculture production. This paper traces the history of the Genetic Improvement of Farmed Tilapia (GIFT) project initiated in 1988 by the WorldFish Center and its partners for the development of methods for genetic enhancement of tropical finfish using Nile tilapia (Oreochromis niloticus) as a test species. It also describes the impacts of the project on the adoption of these methods for other species and the dissemination of improved breeds in several countries in Asia and the Pacific.

Catching and rearing postlarval cleaner shrimp for the aquarium trade: results from a WorldFish Center project in Solomon Islands

Between 1999 and 2003, the WorldFish Center in Solomon Islands conducted research into the feasibility of a new fishery based on the capture and culture of postlarval coral reef fish for the live fish trade. The work was carried out in two phases: a research phase from late 1999 to the end of 2002; and a “finetuning” phase in 2003. Most of the species were of value to the marine aquarium trade, with very few live reef food fish recorded. The most valuable ornamentals were the banded cleaner shrimp, Stenopus species. Cleaner shrimp were harvested using crest nets, the method being modified with the addition of a solid, water-retaining cod-end designed to increase survival at capture. Grow-out techniques were improved by rearing the shrimp separately in jars to prevent aggression. The jars were painted black to protect the shrimp from sunlight. An economic model using experimental catch data and farm gate prices indicates that the fishery based on shrimp, supplemented with small numbers of lobster and fish is economically viable. The next step will be setting up a demonstration farm in a village in the Western Province of Solomon Islands.

European Union supports project to strengthen fisheries and biodiversity management in African, Caribbean, and Pacific (ACP) countries

Proper resource management implies a better understanding of ecosystems and the conservation of biodiversity. Scientists from developing countries often have limited information on their aquatic resources because of many difficulties in accessing and exchanging information on a national and international level. The project described not only aims to strengthen the scientific capacity of fisheries scientists in ACP institutions but it is also expected to create an awareness among fisheries researchers and managers of the importance of conserving biodiversity for the sustainable use of living aquatic resources. This will be achieved through training, building a network of regional and transregional cooperation using modern communication facilities, the promotion of research and the distribution and improvement of fisheries management tools. It is hoped that these capabilities will enable fisheries scientists in ACP countries to actively contribute towards a discussion to solve common problems originating from the endangering of the ecological basis of their fisheries.

River Dart Salmon Project. Summary of Phase I report.

This is the River Dart Salmon Project Summary of Phase I Report (2002) by the Westcountry Rivers Trust. The report contains sections on the introduction to Dart Salmon, factors affecting salmon numbers, salmon rod catch and salmon electro-fishing data, and a summary and discussion of the next phase. It also contains two tables with time series analysis on fry/parr numbers in representative section of the River Dart and figures with trends in fry/parrs numbers at juveniles electro-fishing sites. The section on salmon rod catch data includes trend analysis, cross-correlation of catches in different rivers and a general conclusion.
