Genome Expansion of ZPB1(a) and ZPC1(a) in Basal Species or Liver Expression of ZPB1a and ZPC1aa in Advanced Species, Two Different Strategies to Ensure Sufficient ZP Synthesis in Teleosts

Integrative Zoology, EarlyView.
We found that teleosts employed two different strategies to ensure sufficient ZP (zona pellucida) synthesis: expansion of ZPB1(a) and ZPC1(a) in basal species or liver expression of ZPB1a and ZPC1aa in advanced species. The N‐terminus of expanded ZPB1(a) or ZPC1(a) and liver‐expressed ZPB1a contains repeated units or low‐complexity regions to form ...

Free Plasma Estrogens in the Channel Catfish.

Experimental Biology and Medicine, 1966
SummaryIsolation of free plasma estrogens from blood and ovaries of the Channel Catfish, Ictalurus punctatus, led to identification of 16-ketoestradiol, estriol, epiestriol, estrone, estradiol-17α and estradiol-17β. It was found that as the ovary increases in weight at 1–3 weeks before spawning, there is a gradual increase for all free plasma estrogens.

Generation of Myostatin Gene-Edited Channel Catfish (Ictalurus punctatus) via Zygote Injection of CRISPR/Cas9 System

Scientific Reports, 2017
The myostatin (MSTN) gene is important because of its role in regulation of skeletal muscle growth in all vertebrates. In this study, CRISPR/Cas9 was utilized to successfully target the channel catfish, Ictalurus punctatus, muscle suppressor gene MSTN ...

Using Long‐Term Monitoring Data to Assess Temporal Patterns in Fish Community Assemblages in Florida Lakes

Fisheries Management and Ecology, EarlyView.
ABSTRACT In an effort to increase the relevancy of fish community data for management, we used fish community data to conduct a statewide assessment of Florida's freshwater fisheries resources and compare the relationships between environmental factors and freshwater fish communities over time.

Antibody response of channel catfish after channel catfish virus infection and following dexamethasone treatment [PDF]

Diseases of Aquatic Organisms, 2011
Channel catfish virus (CCV, Ictalurid herpesvirus 1) and CCV disease have been extensively studied. Yet, little is known about CCV-host interaction after resolution of the primary infection. In order to determine potential recrudescence of CCV from latency, we established latency by exposing channel catfish juveniles with CCV or a thymidine kinase ...

Environmental DNA mitochondrial markers to assess potential occupancy of Endangered Yaqui catfish in the Yaqui River basin, Mexico

Endangered Species Research
Acquiring data on rare and threatened species can be challenging, particularly in remote areas. Environmental DNA (eDNA) offers a less effort-intensive method for detecting species compared to physical fish sampling methods.

Site Fidelity, Depth Preference and Vertical Movement Patterns of Lentic and Lotic European Catfish Silurus glanis

Fisheries Management and Ecology, EarlyView.
ABSTRACT To study variables that may trigger the dispersion of the currently expanding European catfish in its native distribution limits, 42 individuals were captured from Upper Lake Constance (lentic) and 42 from two streaming tributaries (lotic), fitted with pressure and temperature loggers, and released at the site of capture (control: lotic or ...

A wild‐caught rosy barb Pethia conchonius in a British urban pond underscores the need to prevent aquarium releases

Journal of Fish Biology, EarlyView.
Abstract A specimen of rosy barb Pethia conchonius of 51 mm standard length, encountered in an urban pond in London, is reported. This small cyprinid is native to lakes and streams in subtropical regions of southern Asia and is commonly sold as an ornamental fish.

Relationship between the environment and the occurrence of invasive pumpkinseed Lepomis gibbosus in lotic and lentic habitats

Journal of Fish Biology, EarlyView.
Abstract The pumpkinseed Lepomis gibbosus is a freshwater fish species native to North America. It has been introduced to Europe, where it is recognized as one of the worst aquatic invaders due to its high adaptability and invasive potential. This study aimed to determine the presence of L. gibbosus in small to medium‐sized water bodies, both lotic and
