Croissance, production et demande d'énergie d'une population de soles (Solea vulgaris) introduite dans une lagune aménagée (bassin d'Arcachon) ArchiMer
Lasserre, G.; Lasserre, P..
Population of 4000 soles received from an induced spawing (COB-BREST), with a mean weight o£ 54 mg were introduced into a man modified lagoon (1000 m2 ) at Certes (4 soles/m2 ). The experiment was continued until December 1977 and permitted an analysis of the demographic evolution of the population : structure number, biomass, growth, production. Simultaneously an estimate of the trophic support necessary for the population derived by correlating oxydative demands with rate of oxygen consumption, was determined experimentally with specimens obtained during the samplings for growth and production (19 VII, 14 IX, 24 XI, 20 XII 1977). 1°) The demographic evolution of the population shows a rapid growth and a strong spread in size. For the short duration of...

Dietary canitine maintains energy reserves and delays fatigue of exercised african catfish (Clarias gariepinus) fed high fat diets Scientia Agricola
Ozório,Rodrigo; Van Ginneken,Vincent; van den Thillart,Guido; Verstegen,Martin; Verreth,Johan.
Lipids, together with proteins, are traditionally considered as primary fuels during aerobic swimming. The effects of dietary fat and carnitine supplements and exercise on the energy metabolism of juvenile fish were investigated. One hundred African catfish (Clarias gariepinus) were fed four isonitrogenous diets containing a fat level of 100 or 190 g kg-1 diet and one of the two levels of carnitine (15 and 1000 mg kg-1). Fish grew from 61 to 162 g in 10 wk. Thereafter, 6 fish per group swam vigorously for 3 h and the results were compared with unexercised groups. Fish receiving 1,000 mg carnitine accumulated 2- to 3-fold more carnitine than fish receiving 15 mg carnitine. Plasma acyl-carnitine level was affected by an interaction between dietary treatment...

Feeding rate for pacu reared in net cages R. Bras. Zootec.
Hilbig,Cleonice Cristina; Boscolo,Wilson Rogério; Feiden,Aldi; Dieterich,Fabiana; Lorenz,Evandro Kleber; Zaminhan,Micheli.
The objective of this study was to evaluate the feeding management of pacu juveniles (P. mesopotamicus) under different feeding rates and its relation with productive performance, body composition and hematological characteristics. A total of 300 fish with initial weight of 84.75±4.52 g were distributed in a completely randomized design composed of four treatments (100, 90, 80 and 70% of feed supply) and five repetitions. The amount of feed was stipulated according to the quantity supplied in the treatment until apparent satiation (100%) of the day before. The decrease in the feeding rate to 70% over satiation apparently improves the apparent feed conversion without harming performance, body composition or biochemical and hematological characteristics of...

Incidencia de Yersinia ruckeri y Edwarsiella sp. en especies de interés comercial de la acuicultura cubana en el período 2006-2008 OceanDocs
Martínez, M. T.; Aguilera, Y.; Pozo, M.; Silveira, R.; Rubio, M.; Amador, Z.M..
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...
