“…While these crosses have not always consistently shown the type of positive effects of heterosis seen in some other cases of hybrid formation, the hybrid fish produced do appear to combine the meat quality of C. macrocephalus with the high growth rate and environmental tolerances that C. gariepinus is known for (Koolboon et al, 2014). Some improvement in growth-related parameters of hybrids was also seen in a study of reciprocal crosses between C. gariepinus (an exotic species) and C. jaensis (a native species) in Cameroon (Tiogue et al, 2020), and similar results were seen in hybrids between C. gaiepinus and C. anuillaris in Nigeria (Akinwande et al, 2012). Finally, Na-nakorn et al (2004) also showed that hybrids could be used to induce the formation of triploid fish.…”

Catfish are important organisms used extensively in aquaculture. For this review, we are focusing on specific species of catfish in the genus Clarias, primarily Clarias batrachus, C. gariepinus and C. macrocephalus, because of their widespread use in aquaculture and the considerable amount of information that has been amassed on different aspects of their biology. This review summarizes information available on topics ranging from the taxonomy and geographic distribution of these catfish to work done on them at the genetic, molecular biological and genomic levels. This information may be useful in future efforts to grow and expand their use in aquaculture.

“…Reciprocal crosses of other species like brown trout (Ågren et al., 2019; Altinok et al., 2020), Clarias sp. (Akinwande et al., 2012), and Nile tilapia ( Oreochromis niloticus ) (Neira et al., 2016) were found to be prominent over their best pure line.…”

The present study aimed to improve the growth rate of the Bangladeshi native climbing perch (Anabas testudineus) through crossbreeding with Vietnam‐originated climbing perch, which is commercially cultured in Bangladesh. Therefore, crossbred between native and Vietnam strains of A. testudineus were evaluated in the first year (F1) as T1—Native ♀ × Native ♂, T2—Vietnam ♀ × Vietnam ♂, T3—Native ♀ × Vietnam ♂, and T4—Vietnam ♀ × Native ♂. In the second year (F2), backcrosses were performed between native and F1 generations as T5—Native ♀ × F1 (T3) ♂ and T6‐F1 (T3) ♀ × Native ♂ following five replicates in each treatment group. The F1 crossbreds of T4 were irregular in size with low survivability than T3, and therefore were not used as a parent in the second‐year backcross experiment. The breeding performances were reduced in the T4 (F1) and T6 (F2) compared to purebreds (T1 and T2). The specific growth rate (0.75%/day) of T5 and T6 was substantially lower than T3 and T4 but was considerably superior to the T1 and T2 purebred. The heterosis effect was highly evident in T6 (27.94%), whereas negative heterosis was determined in the crossbreds of the F1 generation (T4). Ten morphometric characteristics were compared and the caudal fin length, pectoral fin length, eye diameter, and body depth were responsible for the variation among T1–T6 groups by the second principal component. Furthermore, the results showed that the Bangladeshi native female climbing perch is linked with better breeding performances, and the Vietnam strain male is linked with better growth performance. Finally, the current breeding programme could enhance native climbing perch growth and survivability, which may have aquaculture potential and can be used through careful artificial selection on the commercial farm.

“…with the fast growth rate of C. gariepinus [8,9]. There is a paucity of reports on C. macromystax potentials of culture in captivity and an estimate of broodstock yield through gonadosomatic indices, partly due to the high cost of the fish [10][11][12]. The current study was designed to evaluate the reproductive traits of C. gairepinus and C. macromystax and their relationship with broodstock sizes [13,14].…”

The study evaluates the hybridizations between two African catfish, C. gariepinus and C. macromystax, using artificial reproduction. Fecundity and gonadosomatic index were assessed, and growth performance at different developmental stages was evaluated. The results indicated that both species possess a similar gonadosomatic index. The parent C. gariepinus possesses significantly (p < 0.05) higher male reproductive quality than C. macromystax. Fecundity was significantly higher (p < 0.05) in the female parent of C. macromystax and lower in C. gariepinus. The highest fertilization rates and hatching rates were achieved in the hybrid cross of ♀C. macromystax × ♂C. gariepinus (♀Cm × ♂Cg) which also recorded the lowest deformed larva rate. Survival rates at the larval stage were more than 80%, with the highest record of survival in the hybrid ♀Cm × ♂Cg. However, survival rates in the fry stage were lower than 70%. The hybrid cross (C. macromystax × C. gariepinus) outperformed the parental cross of C. macromystax but was not significantly similar to the parental cross of C. gariepinus. The study revealed the potential of the hybrid ♀C. macromystax × ♂C. gariepinus, and hybridizations of ♀C. macromystax × ♂C. gariepinus (♀Cm × ♂Cg) are indeed possible and proved to have a better growth and survival rate under semi-arid conditions, which would contribute significantly to the improvement of C. macromystax production in captivity.
