Development of digestive tract and enzyme activities during the early ontogeny of the tropical gar Atractosteus tropicus

Fish Physiology and Biochemistry, 2015
Changes in digestive enzyme activity and histology were studied in Atractosteus tropicus embryos, larvae and juvenile periods. Alkaline protease, chymotrypsin, carboxypeptidase A, lipase and α-amylase were detected in all periods and gradually increased until reaching the maximum peak in juveniles; meanwhile, acid protease was first detected at 5 days ...

Genetic variation and recent population history of the tropical garAtractosteus tropicusGill (Pisces: Lepisosteidae)

Journal of Fish Biology, 2008
The tropical garAtractosteus tropicusbelongs to one of the few extant lineages of early bony fishes. The genetic variation detected both within and among 11 natural populations ofA. tropicusin Mesoamerica along with the implications for their recent history are presented.

CYSTOOPSIS ATRACTOSTEI N. SP. (NEMATODA: CYSTOOPSIDAE) FROM THE SUBCUTANEOUS TISSUE OF THE TROPICAL GAR, ATRACTOSTEUS TROPICUS (PISCES), IN MEXICO

Journal of Parasitology, 2003
A new species of parasitic nematode, Cystoopsis atractostei (Trichinelloidea: Cystoopsidae), is described based on female specimens recovered from the subcutaneous tissue of the tropical gar, Atractosteus tropicus Gill (Lepisosteiformes: Lepisosteidae), from 2 localities (Canal Nueva Esperanza and Canal Tabasquillo) of the Pantanos de Centla Biological
