Optimum level of dietary lipids for growth, chemical composition and apparent digestibility of lipids for Atractosteus tropicus

Latin American Journal of Aquatic Research, 2018
Lipids requirement of tropical gar Atractosteus tropicus prejuveniles and juveniles was evaluated on growth, survival, chemical composition and apparent digestibility coefficient (ADC). Four semi-purified experimental diets (5, 10, 15 and 20% of lipids) were obtained with a mix of menhaden oil and soybean lecithin (2:1 ratio). Two trials were carried

Evaluation of microencapsulated diets for tropical gar (Atractosteus tropicus) larviculture

, 2018
Four microencapsulated diets were evaluated with respect to the growth and survival of tropical gar Atractosteus tropicus larvae. The treatments consisted of four experimental diets and one control diet 1) fish meal, 2) a combination of pork and poultry meals, 3) Nannochloropsis gaditana meal, 4) enzyme preparation and the control treatment 5) Artemia ...

Permanent germinal epithelium and reproductive cycle of Atractosteus tropicus (Lepisosteiformes: Lepisosteidae) males, Tabasco, Mexico.

Revista de biologia tropical, 2016
A. tropicus tiene un papel ecológico importante, como regulador de otras poblaciones de peces, en los cuerpos de agua de México, pero sus poblaciones silvestres se reducen. Una alternativa de conservación es el cultivo, el cual requiere caracterizar el ciclo reproductivo por medio del estudio de estructuras germinales y somáticas de los testículos ...
