Determination of optimal prey for rearing tropical gar Atractosteus tropicus (Lepisosteiformes: Lepisosteidae) [PDF]
Revista de Biología Tropical, 2018 Larval feeding studies of both ornamental and consumable fish species are important for formulating successful management, and culture strategies for conservation purposes. In the present study, we evaluated prey selectivity for the tropical gar Atractosteus tropicus in the larval stage (first 8 weeks) using the zooplankton Artemia fransiscana, Daphnia

Improvement of Fish Growth and Metabolism by Oligosaccharide Prebiotic Supplement. [PDF]
Aquac Nutr, 2022 Finfish aquaculture is expected to continue to benefit from significantly improved fish diets, which are the source of energy to support the growth and health of fish. Strategies to enhance the transformation rate of dietary energy and protein to fish growth are greatly desired by fish culturists. Prebiotic compounds can be used as supplements to human,

Estado de arte de la biología y cultivo de pejelagarto (atractosteus tropicus) [PDF]
Native fresh water fish are an important source of food and protein for human society. A full study of the native aquatic species and the development of technologies that allow the controlled production of these fish in a profitable, innocuous and environment-friendly manner, are some of the big challenges for aquaculture in this millennium. Therefore,

Aquaculture Research, 2020 Supplementary fructooligosaccharides (FOS) were evaluated on growth, survival, gut morphology, digestive enzyme activity and expression of intestinal barrier genes in tropical gar (Atractosteus tropicus). Four treatments were designed to include FOS (5, 10, 15 and 20 g/Kg) and were compared with a control (0 g/Kg) and the current commercial trout diet.
