Potential of meat meal to replace fish meal in extruded dry diets for barramundi, Lates calcarifer (Bloch). I. Growth performance

Abstract

Juvenile barramundi (∼220–280 g start weight) were fed extruded dry‐pelleted diets containing varying amounts of fish meal and meat meal in three experiments (E). E1 and E2 were each 66‐day farm studies utilizing 16 floating cages (400 fish per cage) in an aerated freshwater pond. E3 examined the same diets as fed in E2 but under controlled water temperature (28 ± 0.7 °C) and photoperiod (12:12) laboratory conditions in a 42‐day study involving 24 aquaria (eight fish per aquarium). In all studies, the same 430 g kg−1 crude protein (CP), 15 kJ g−1 digestible energy (DE) control (Ctl) diet (containing 35% Chilean anchovy fish meal) was compared with two high‐inclusion meat meal diets and a proprietary diet. The meat meal diets evaluated in E1 were a high‐ash (260 g kg−1) meat meal that contained 520 g kg−1 CP and a low‐ash (140 g kg−1) meat meal that contained 600 g kg−1 CP when included at either 450 or 400 g kg−1, respectively, in combination with 100 g kg−1 Chilean fish meal in diets that were isonitrogenous and isoenergetic with the Ctl diet. Growth rates and feed conversions were similar (P > 0.05) for all diets. In E2 and E3, the 520 g kg−1 CP meat meal was included at 500 g kg−1 without any marine protein source in diets formulated to provide either 15 or 16.2 kJ g−1 DE and the same CP/DE ratio (29 mg kJ−1) as the Ctl diet. Fish performance ranking of diets was similar in both experiments, with the 16.2 kJ g−1 DE diet supporting better (P < 0.05) growth rates than the Ctl diet and feed conversion ratios equivalent to the Ctl diet but better (P < 0.05) than all other diets.

Evaluación de dietas formuladas para la corvina rubia, Micropogonias furnieri (Osteichthyes: Sciaenidae)

“…Estos resultados indican un punto de partida en la formulación de dietas artificiales para esta especie. Williams et al (2003), evaluando reemplazos utilizando harina de carne en Lates calcarifer, obtuvieron tasas de crecimiento y de conversión del alimento similares a la dieta con harina de pescado. Kikuchi et al (1997) obtuvieron resultados similares trabajando con Paralichthys olivaceus, y al igual que Shimeno et al (1993Shimeno et al ( , 1996 con Seriola quinqueradiata; Sadiku et al (1995) con Oreochromis niloticus y Watanabe et al (1993) con Oncorhynchus mykiss, concluyeron que la harina de carne y en general las fuentes proteicas de origen animal como fuente alternativa, son mejores que aquellas de origen vegetal, en una proporción de reemplazo que no exceda el 50% de la fuente proteica.…”

Barramundi Aquaculture

“…2003b ;Glencross 2006 ;Katersky & Carter 2009 ). Meat meal successfully maintained growth rates and protein growth effi ciency at inclusion levels of 40 -50% (Williams 1998 ;Williams et al . 2003b ).…”

Influence of poultry meal, meat meal or soybean meal inclusion on weight gain and production characteristics of Australian snapper Pagrus auratus

“…Much of the recent literature has focused on plant proteins, but rendered animal meals still appear to be a more practical alternative for carnivorous fish in terms of protein content and cost (Williams et al 2003). This is especially true in Australia, where stocks of rendered animal meals are readily available and generally of high quality.…”

“…It is now acknowledged, however, that the global demand for these resources will eventually outstrip supply and alternative ingredients sourced from more sustainable sectors will have to be used (Tacon 2003;Williams et al 2003;Allan 2004).…”
