Abstract The Yaqui Catfish Ictalurus pricei is an understudied species, with limited information available on its ecology, distribution, and local habitat use. Native to the southwestern United States northwestern Mexico, populations are declining, which has prompted listing of species as threatened in a concern Mexico. Water overallocation, degradation, invasive introductions, hybridization no...

Toll like receptor (TLR) signalling pathway plays a central role in inflammatory responses through the recognition of PAMPs and DAMPs. Toll-like 4 (TLR4) is well known for LPS gram-negative bacteria leading to production cytokines. Modulation TLR gene different tissues indicates functional importance innate immunity. The aim this study was clone characterize TLR4 evaluate its constitutive tissu...

Abstract Catfishes (Ictaluridae) are among North America’s most important ichthyofauna for human consumption and recreation. As such, research on Blue Catfish Ictalurus furcatus , Channel I . punctatus Flathead Pylodictis olivaris has been abundant in historic contemporary literature. A common technique studying catfish involves marking or tagging fish to understand behavior, sampling efficienc...

Understanding farm-level efficiencies of resource use is critical in comparisons the sustainability aquaculture production systems. We developed a set practical resource-use efficiency metrics to calculate and compare with resource-cost across major species systems US aquaculture. Results showed that no one system used all resources most efficiently. Intensive pond channel catfish Ictalurus pun...

Abstract The skeleton of Siluriformes is characterized by several autapomorphies, including secondary absence, extreme modification, and purported fusion ossifications. Although well documented in adults, information on skeletal development catfishes relatively sparse typically focused particular regions the (e.g., Weberian apparatus). To further our understanding siluriform skeleton, I documen...
