“…2020), and even genomic editing (Elaswad et al. 2018; Patiño 2019) are all possible using genetic markers. These tools have promise for management of recreational catfish fisheries, conservation of imperiled catfish, and suppression of invasive populations, but they require additional evaluation and collaboration with qualified geneticists to ensure proper methods (Higgins 2006; Turner and Robison 2006; Duong and Scribner 2018; Garcia et al.…”

“…Technology associated with genetic marking is rapidly improving and introduces novel tools to evaluate fish populations (Campbell et al 2019;Bunch et al 2020;Hsu et al 2020). For example, examination of effective population size (Luikart et al 2010;Gossieaux et al 2019), parentage assignment of stocked fish (Waldbieser and Bosworth 2013), selective breeding in aquaculture (Bosworth et al 2020), and even genomic editing (Elaswad et al 2018;Patiño 2019) are all possible using genetic markers.

Catfishes (Ictaluridae) are among North America’s most important ichthyofauna for human consumption and recreation. As such, research on Blue Catfish Ictalurus furcatus, Channel Catfish I. punctatus, and Flathead Catfish Pylodictis olivaris has been abundant in historic and contemporary literature. A common technique for studying catfish involves marking or tagging fish to understand behavior, sampling efficiency, and population dynamics. Marking and tagging methods used in these studies may be divided into eight primary types, including fin clips, strap tags, anchor tags, transbody tags, injectable tags, skin alterations, origin markers, and telemetry. Each of these methods is appropriate for specific objectives and characterized by varying retention rates and data resolution (i.e., batch or individual identification) that warrant consideration when designing projects. For example, fin clips may be most appropriate as a short‐term mark requiring batch identification (e.g., stocking evaluation), whereas telemetry might be most appropriate as a long‐term tag requiring individual identification (e.g., habitat selection). This review summarizes marking and tagging methods used for evaluation of Blue, Channel, and Flathead catfish and synthesizes results using examples from previously conducted catfish research. Further discussion is included on information gaps, emerging trends, and guidance for scientists planning and conducting studies that require marking of catfish.

“…There is evidence suggesting that the gene transcripts gsdf and cxcl12 are involved with testicular differentiation in several teleost species. The gsdf gene is teleost specific (and a member of the TGF‐beta family) and appears to be involved with testicular differentiation in medaka (Myosho et al ., 2012; Zhang et al ., 2016), Nile tilapia Oreochromis niloticus (Linnaeus 1758) (Kaneko et al ., 2015; Jiang et al ., 2016), zebrafish (Presslauer et al ., 2014) and possibly channel catfish (Patiño, 2019; Zeng et al ., 2016). Moreover, gsdf is responsible for the modulation of primordial germ cell proliferation and development of testis and ovary (Hsu & Chung, 2021).…”

“…In addition, in channel catfish, cxcl12 was found to have testis‐biased expression similar to that of gsdf (Zeng et al ., 2016). It is suggested that cxcl12 is involved in the early organization of testicular tubules in channel catfish (Patiño, 2019). Moreover, cxcl12 together with its receptor, CXCR4 expressed on the primordial germ cells, is a critical component of mechanisms regulating primordial germ cell migration to the gonadal ridges as observed in zebrafish and Japanese eel Anguilla japonica (Temminck & Schlegel 1846) (Saito et al ., 2011).…”

The bidirectional interaction between the hypothalamic-pituitary-gonadal (HPG) axis and the immune system plays a crucial role in the adaptation of an organism to its environment, its survival and the continuance of a species. Nonetheless, very little is known about this interaction among teleost, the largest group of extant vertebrates.Fishes being seasonal breeders, their immune system is exposed to seasonally changing levels of HPG hormones. On the contrary, the presence and infiltration of leukocytes, the expression of pattern recognition receptors as well as cytokines in gonads suggest their key role in teleostean gametogenesis as in the case of mammals. Moreover, the modulation of gametogenesis and steroidogenesis by lipopolysaccharide implicates the pathological significance of inflammation on reproduction. Thus, it is important to engage in the understanding of the interaction between these two important physiological systems, not only from a phylogenetic perspective but also due to the importance of fish as an important economic resource. In view of this, the authors have reviewed the crosstalk between the reproductive and immune systems in teleosts and tried to explore the importance of this interaction in their survival and reproductive fitness.

“…The genetic and epigenetic processes involved in regulation of sex-change in fish have been well reviewed by Ortega-Recalde et al [ 131 ]. Additionally, sex determination/differentiation and feminization in the Southern catfish, S. meridionalis [ 132 ] and the channel catfish, I. punctatus [ 133 ] has been reviewed wherein gdsf and cxcl12 plausibly initiated testicular differentiation as demonstrated in channel catfish. The genetic basis of sex determination/differentiation in fishes has been reviewed by Nagahama [ 134 ].…”

Catfishes, belonging to the order siluriformes, represent one of the largest groups of freshwater fishes with more than 4000 species and almost 12% teleostean population. Due to their worldwide distribution and diversity, catfishes are interesting models for ecologists and evolutionary biologists. Incidentally, catfish emerged as an excellent animal model for aquaculture research because of economic importance, availability, disease resistance, adaptability to artificial spawning, handling, culture, high fecundity, hatchability, hypoxia tolerance and their ability to acclimate to laboratory conditions. Reproductive system in catfish is orchestrated by complex network of nervous, endocrine system and environmental factors during gonadal growth as well as recrudescence. Lot of new information on the molecular mechanism of gonadal development have been obtained over several decades which are evident from significant number of scientific publications pertaining to reproductive biology and neuroendocrine research in catfish. This review aims to synthesize key findings and compile highly relevant aspects on how catfish can offer insight into fundamental mechanisms of all the areas of reproduction and its neuroendocrine regulation, from gametogenesis to spawning including seasonal reproductive cycle. In addition, the state-of-knowledge surrounding gonadal development and neuroendocrine control of gonadal sex differentiation in catfish are comprehensively summarized in comparison with other fish models.
