A growth model for coho salmon including effects of varying ration allotments and temperature

Growth performance and body composition of Oreochromis niloticus reared at different water temperatures

“…The specific growth rate of most of the fish species increases with increasing temperature, provided the food supply is not limited (Corey et al, 1983;Heap and Thorpe, 1987;Talbot, 1993). The increase in growth rate reflects the increase in appetite, food consumption and biochemical reaction rate within the thermal tolerance range of fish (Brett and Groves, 1979;Jobling, 1993).…”

“…Fat and ash contents decreased and moisture content increased as the water temperature increased, whereas the crude protein and gross energy contents of fish were not affected (P > 0.05). Our (Brett et al, 1969;Corey et al, 1983;Jobling, 1994). For most of the fish species studied so far, when the food supply is not limited, the specific growth rate of fish has been found to increase with increasing temperature, until the optimum temperature, above which it declines (Talbot, 1993).…”

Some aspects of the biology of feeding and growth in fish

“…based on either theoretical considerations of bioenergetics or on empirical studies, to describe the growth process in fish in numerical terms, and to quantify the influence of biotic and abiotic factors on growth (Ricker, 1979). In situations where food is not limited in quality or quantity, the two factors having the greatest influence on growth in fish are temperature and fish size (Corey et al 1983).…”

Modelo explicativo de la rentabilidad de las empresas de piscicultura marina. Aplicación empírica a la cría de dorada (Sparus aurata) y lubina (Dicentrarchus labrax) en España

“…El factor medioambiental que concentra más trabajo de investigación es la temperatura del agua, considerado por muchos autores como el aspecto medioambiental que más influye sobre la tasa de conversión del alimento y el crecimiento y, en consecuencia, sobre el rendimiento económico de la actividad (Hernández et al, 2007;Hernández et al, 2003;Gasca-Leyva et al, 2002;Calderer, 2001;Corey et al, 1983;Brett y Groves, 1979). En el caso de la dorada y la lubina, la relación entre la temperatura media del agua y el crecimiento es una curva con un máximo denominado temperatura óptima, próximo a 25 ºC en la dorada (Gasca-Leyva et al, 2002) y a 26 ºC en la lubina (Person-Le Ruyet et al, 2004), disminuyendo progresivamente el crecimiento a medida que la temperatura se aleja de dicha temperatura óptima.…”
