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.

Dos prelos da impressão régia, a cultura científica do período joanino (1808-1821)

O presente estudo examina o momento fundador da imprensa no Brasil em 1808 e a rotina de funcionamento da Impressão Régia, no Rio de Janeiro, entre 1808 e 1821. Qual era sua estrutura administrativa, sua ordem de despesas, a natureza das ocupações funcionais, enfim, qual era a lógica de funcionamento da casa impressora oficial da Corte no início do Oitocentos? Qual o lugar ocupado pelos impressos naquele contexto?Para melhor compreender a estrutura, a rotina administrativa e de funcionamento da Impressão Régia no Rio de Janeiro, mas, principalmente, os usos e funções da régia tipografia no momento de seu estabelecimento por iniciativa do príncipe regente d. João, foi analisada também parte de sua produção, qual seja, os títulos dedicados às Ciências e às Artes. A partir desses livros, localizados no acervo da Biblioteca Nacional do Rio de Janeiro e na Biblioteca Guita e José Mindlin, em São Paulo, foram estudadas as características biobibliográficas de seus autores e a relação dos mesmos com o poder oficial.Foi possível identificar que os autores dos títulos examinados eram herdeiros da tradição ilustrada portuguesa. Partilhando de uma mesma cultura política, possuíam laços estreitos com membros da Corte, prestando obediência ao príncipe, sendo alguns autores, inclusive, integrantes da junta diretora da Impressão Régia.Assim, além da rotina e funcionamento da casa impressora da Corte, no Rio de Janeiro de d. João, o presente trabalho examina tomando como fonte de análise sua produção editorial no campo das Ciências e das Artes a formação da cultura científica do período Joanino e a rede de sociabilidades existente no Rio de Janeiro, entre 1808 e 1821.

Kumataro Ito, Japanese Artist on Board the U.S. Bureau of Fisheries Steamer Albatross During the Philippine Expedition, 1907–1910

Kumataro Ito produced hundreds of beautiful color paintings of fishes and invertebrates during and after the 1907-10 Philippine Expeditin of the U.S. Bureau of Fisheries Steamer Albatross. The paintings are housed in the files of the Divisions of Fishes and Mollusks, United States National Museum of Natural History, and Smithsonian Institution Archives, Washington, D.C. Few of those paintings have been published in color, but many have been publishes in black and white. Two years after the expedition, Ito came to Washington, D.C., in 1912 for an extended period to render final paintings based on preliminary color sketches made during the expedition. He did not completly render all the sketches during his stay, probably because he was asked to produced a large number of black-and-white illustrations of Philippine fishes, and a few of North American fishes. Most of the black-and-white illustrations have been published. Few publications containing Ito's Philippine and North American illustrations have acknowledged him. The very little that is known about Ito's life is discussed, examples of his black-and-white and colored fish paintings are reproduced, and his previously unacknowledged illustrations in various publications are herein acknowledged. Another Japanese artist, Yasui, about whom almost nothing is known, joined the Albatross during Ito's second tour on board the ship. It appears, with few exceptions, that Yasui produced only preliminary color sketches of fishes, which, if rendered as final paintings, were done by Ito.

A Single-armed Manta-board as a New Diver-controlled Planing Board and Its Use for Underwater Surveys

Due to inadequacies of previous underwater towing techniques and the special needs of a recent underwater survey, a modified mania-board technique was developed. With this new technique, the diver holds on to the manta-board with one arm; consequently, the board is referred to as a single-armed manta-board (sam-board). The sam-board proved inexpensive and highly maneuverable, allowing the divers to freely collect samples or record information. Through some experimenting with the board and changing some of the variables, such as rope lengths, towing speeds, etc., a highly efficient towing method can be achieved. Preplanning and strict diving safety procedures must, however, be implemented to assure efficiency. This paper presents the materials, guidelines for board construction, equipment, and preplanning and diving safety procedures necessary for the sam-board towing operation.

Report to the Devon River Board on the investigations in the Walla Brook

This is the Report to the Devon River Board on the investigations in the Walla Brook (1955-58). This report provides information on the nature and quantification of the bottom fauna, the population of fish and their habits and behaviour throughout the year, and the relation of this fish population to the potential stock-carrying capacity of the river. It includes a bottom fauna list with occurring invertebrates and an Addendum to the report.
