Metabolic differentiation of diploid and triploid European sea bass juveniles

Haematological and physiological characteristics of diploid and triploid sea bass, Dicentrarchus labrax L

The purpose of this study was to determine whether diploid and triploid sea bass differed in terms of main haematological and physiological characteristics. Diploid and triploid fish were produced by sub-optimal pressure treatments and held in communal environments under standard rearing conditions. Total red blood cell count (RBCC), haemoglobin concentration (Hb), hematocrit (Hct), mean cell v...

Dietary carbohydrate and lipid source affect cholesterol metabolism of European sea bass (Dicentrarchus labrax) juveniles.

Plant feedstuffs (PF) are rich in carbohydrates, which may interact with lipid metabolism. Thus, when considering dietary replacement of fishery by-products with PF, knowledge is needed on how dietary lipid source (LS) and carbohydrates affect lipid metabolism and other metabolic pathways. For that purpose, a 73-d growth trial was performed with European sea bass juveniles (IBW 74 g) fed four d...

Rapid metabolic adaptation in European sea bass (Dicentrarchus labrax) juveniles fed different carbohydrate sources after heat shock stress.

A study was conducted to evaluate the effect of two dietary carbohydrate sources (waxy maize starch and glucose) on the metabolic adaptation of sea bass juveniles (initial weight: 24 g) to a heat shock treatment (temperature rise from 18 degrees C to 25 degrees C within 24 h). Two isonitrogenous and isolipidic diets were formulated to contain 20% waxy maize starch (WS diet) or 20% glucose (GLU ...

Comparison of Diploid and Triploid Largemouth Bass Growth and Maturation in Puerto Rico

Triploid largemouth bass may have potential in sport fish management and in food fish production as a means to eliminate reproduction, which would, in turn, potentially increase somatic growth. To examine this potential, four cohorts of diploid and triploid largemouth bass were produced over a 10-yr period and tagged intramuscularly with coded wire tags. Bass were stocked into Lucchetti Reservo...
