Abstract:
... Tandem hoop nets have become the primary gear for sampling channel catfish Ictalurus punctatus, but suffer from high incidences of bycatch, particularly aquatic turtles that usually drown as a result. We sought to determine if bait type, ZOTE© soap and ground cheese logs, would influence catch of channel catfish (CPUE and mean TL) and bycatch of fishes and aquatic turtles. We sampled with tandem h ...

Reported to specifically target the adipose fin, H. adiposa is not associated with morbidity or mortality, although detailed descriptions of its associated histologic pathology are lacking. The objective of this work was to confirm the prese ...

Polyadenylation plays important roles in gene expression regulation in eukaryotes, which typically involves cleavage and poly(A) tail addition at the polyadenylation site (PAS) of the pre-mature mRNA. Many eukaryotic genes contain more than one PASs, termed as alternative polyadenylation (APA). As a crucial post-transcriptional regulation, polyadenylation affects various aspects of RNA metabolism ...
