The fishery products are sources of protein of high biological value and an important component in a balanced diet. However, they are highly subject to deterioration, which represents a serious risk to public health. Thus, rigorous methods are needed for quality assurance of fish in all stages of the production chain. Traditionally, the Brazilian population does not have the habit of eating fish, although the country presents a great potential for aquaculture, which is underexploited. The consumption of fish is limited by socio-economic factors. Currently, the search for food security is a global trend. Thus, it is necessary to change the profile of the consumer, by offering a competitive and safe food. In this paper, we address issues related to quality, hygiene and health of fish

This study aimed to evaluate possible histopathological liver of tilapia fed diets containing fish silage and level protein. Sample of 180 fed with tilapia fingerlings fed with diets containing three protein levels (20, 24 and 28% CP), and Proportions residue fermented silage of tilapia (1/4 and 1/2) of were analyzed during 75 days. The tissue fragments were fixed in Bouin and included in Histosec (R). After that, between 2 to 5 mu m slices were done in a rotation microtome. The methods used for tissue analysis were hematoxilin/eosin and PAS. The histological slices were examined under light microscope (Olympus BX-50). The disarray in the morphology of the liver of fish fed biological silage was influenced by high protein levels, and increased proportions of 1/2 of animal protein diets. It was observed that the variation of hepatocytes is directly related to the type of diet for fish. In fish fed diets containing 28% CP, the liver showed disruption of the structure cordon of hepatocytes, necrosis and shifting points of the core to the periphery. Elevated levels of biological fish silage cause deleterious changes in the liver. The level of protein required to maintain the health of the associated development fish is 24% crude protein.

[ES] Se estudia la utilización nutritiva de niveles crecientes de cuatro fuentes proteicas, harina de soja, de altramuz, harina de gluten de maíz y harina de carne y huesos, alternativas a la harina de pescado en dietas de engorde para dorada, especie que junto con la lubina ha experimentado uno de los mayores índices de crecimiento en el terreno de la acuicultura en los últimos 20 años en Europa

Abordamos en este trabajo la segunda entrega de los Tipos de Instalaciones de Ordeño, correspondiente a la 2ª parte de un conjunto de artículos que hemos denominado globalmente SALAS DE ORDEÑO. En esta segunda entrega describiremos la que quizá ha sido durante muchos años la sala de ordeño más utilizada por su versatilidad: la sala en ESPINA DE PESCADO. Este tipo de sala de ordeño apareció por primera vez en Australia a principios del siglo XX (1910), se popularizó en Nueva Zelanda a principios de los años 50 de dicho siglo y, una dé- cada después, llegó a Europa, donde se popularizó rápidamente. Se ha utilizado como modelo de referencia, por lo que el resto de tipos de salas de ordeño se analizan frecuentemente (respecto a coste, rendimiento, etc.) por comparación con la espina de pescado
