Las especies Yersinia ruckeri y Edwardsiella sp. son patógenos de importancia económica por la alta morbiletalidad que provocan en la acuicultura. En este trabajo se analiza la frecuencia de aparición y el comportamiento epizootiológico de ambos patógenos en los peces de cultivo en Cuba, en diferentes regiones del país y en sistemas de cultivo extensivo en embalses e intensivo en estanques y jaulas flotantes, del 2006 al 2008. Del total de brotes analizados, estas especies se encontraron en 18 eventos epizoóticos, cuatro en el 2006, 12 en el 2007 y dos en el 2008. Edwardsiella sp. se aisló en 16 de ellos, mientras que Yersinia ruckeri se encontró en nueve. Las especies afectadas fueron Oreochromis sp., Clarias sp. y Micropterus salmoides floridanus. Estos...

Cultivos de moluscos bivalvos
Provedor de dados: 20
Autores: Pascual, M.S.; Zampatti, E.A.
Bivalve culture in Argentina is beginning to develop commercially. Research was carried out at the North Patagonian gulfs (San Matias, San Jose and Nuevo)and focused three native species: the tehuelche scallop Aequipecten tehuelchus, the puelche oyster Ostrea puelchana and the common mussel Mytilus edulis platensis. Results achieved on each of these three species were different. In the case of scallops, the development of commercial aquaculture did not seem promising for many years due to the fact that production was sustained by natural populations: the dredge fishery of the San Matias Gulf and the diving fishery of the San Jose Gulf. Preliminary culture experiments dealt with larval fixation on artificial collectors and growth to commercial size on...

Production and application of on-grown &lt;i&gt;Artemia&lt;/i&gt; in freshwater ornamental fish farm
Provedor de dados: 27
Autores: Lim, L.C.; Soh, A.; Dhert, P.; Sorgeloos, P.
This paper describes a pilot culture system for the production of on-grown &lt;i&gt;Artemia&lt;/i&gt; in freshwater ornamental fish farms. The system had 21 culture units, each consisting essentially of three components: an oval-shaped raceway, an air-water lift system and two waste collectors. Using artificial seawater at 20 ppt for culture and at a mean production rate of 3 kg/m&lt;sup&gt;3&lt;/sup&gt; of water in a 12-day cycle, the system had a production capacity of 8 metric tons of on- grown &lt;i&gt;Artemia&lt;/i&gt; a year. Biochemical analyses were preformed to evaluate the nutritional value of the on-grown &lt;i&gt;Artemia&lt;/i&gt; against three conventional live feeds, viz. live &lt;i&gt;Artemia&lt;/i&gt; nauplii, live &lt;i&gt;Moina&lt;/i&gt;...

Fish and fishery products trade in Brazil, 2005 to 2015: A review of available data and trends

ABSTRACT: Along the last ten years fish and fishery product trade in Brazil has been on a downward trajectory turning a profit of US$ 98.6 million in 2005 into a loss of US$ 1.25 billion by 2014. On the other hand, the country is a leading producer of grains and has the third largest animal feed industry in the world, which has added 5.5 million hectares of freshwater reservoirs and 3.5 million km2 of an exclusive marine economic zone in the same period, a sizable potential for development of the aquaculture industry. This study aims at unveiling strategies for the reduction of the deficit in the Brazilian seafood trade balance, based on critical analysis of the quantitative and qualitative characteristics of imported fishery products. The fish and fishery...
