“…As described in the previous section, dmrt1 along with other factors are known to be the molecular players in testicular differentiation and gamete maturation. In addition, several findings suggested that wt1 , ad4bp/sf-1 , nr2c1 , gata4 , sox3 , sox9 , sycp3 and pfpdz1 have a potential role in the testicular development, maintenance, and recrudescence in catfish by favoring spermatogenesis [ 187 , 188 , 189 , 190 , 191 ]. However, studies on transcriptional networks between nr2c1 and other factors are necessary to demonstrate their interaction during testicular development and spermatogenesis.…”

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.
