Dental development in the tropical gar (Atractosteus tropicus) and the evolution of vertebrate dentitions

Developmental Dynamics
AbstractBackgroundDentitions have diversified enormously during vertebrate evolution, involving reductions, modifications, or allocations to prey seizing and processing regions. A combination of ancient and novel features related to dental and oropharyngeal apparatuses is found in extant lineages of non‐teleost fishes, such as the gars.

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 ...
