Abstract
The development of new strategies for breeding indigenous fish species is of utmost importance in the wake of unfavorable weather events, as a result of climate change. Therefore, an attempt has been made to achieve artificial breeding of an indigenous barb, Puntius sophore. Two groups of juvenile fish, collected from the wild, were reared till sexual maturation. One group was reared under a natural photothermal regime and the other was reared under strictly controlled conditions with photothermal stimulation till sexual maturation and subsequently, hormonal stimulation with OVAFISH was also done for inducement of spawning. The spawning efficiencies were analyzed and the results in terms of latency period (6.74 Hrs), ovulation rate (92.2 %), fertilization rate (90.6 %), hatching rate (89.9 %), and spawning efficiency coefficient (Se) (0.828) were found better in Puntius sophore reared under the indoor controlled condition with photothermal manipulation and hormone administration compared to the group of fish which was reared under a natural photothermal with a hormonal stimulation. The results of this study demonstrate the captive artificial breeding of Puntius sophore spawners reared under a natural photothermal regime and controlled photothermal regime in indoor conditions. The outcome of the present study can be used for developing key strategies for a climate smart aquaculture for fish farmers.

Abstract
In sole aquaculture production, consistency in the quality of produced eggs throughout the year is unpredictable. Hox genes have a crucial role in controlling embryonic development and their genetic variation could alter the phenotype dramatically. In teleosts genome duplication led paralog hox genes to become diverged. Direct association of polymorphism in hoxa1a, hoxa2a & hoxa2b of Solea solea with egg viability indicates hoxa2b as a potential genetic marker. High Resolution Melt (HRM) analysis was carried out in 52 viable and 61 non-viable eggs collected at 54±6 hours post fertilization (hpf). Allelic and genotypic frequencies of polymorphism were analyzed and results illustrated a significantly increased risk for non-viability for minor alleles and their homozygous genotypes. Haplotype analysis demonstrated a significant recessive effect on the risk of non-viability, by increasing the odds of disrupting embryonic development up to three-fold. Phylogenetic analysis showed that the paralog genes hoxa2a and hoxa2b, are separated distinctly in two clades and presented a significant ω variation, revealing their diverged evolutionary rate.

Abstract
Abstract
Common sole (Solea solea) aquaculture production is based mostly on wild-caught breeders. Recently, the successful reproduction of first-generation fish that were reared in captivity was accomplished. A consistent good quality and quantity of produced eggs throughout the year, and of next-generation broodstock, is important for reducing the overall cost of production. Hox genes play a pivotal role in normal embryonic development and alterations of their temporal expression level may be important for egg viability. Expression profile analysis of five hox genes (hoxa1a, hoxa2a, hoxa2b, hoxb1a and hoxb1b) involved in early embryonic development and of hoxa13a, which is involved in late stages, was carried out. Results revealed a premature and/or maternal expression of hoxa13a in sole embryos, and the detection of hoxa2a and hoxa2b genes as members of paralog group 2. Principal Component Analysis of hox gene expression in 54 ± 6 hours post fertilization embryos coming from wild-caught broodstock and a first-generation one reared in the hatchery, unveiled that these broodstocks are clearly distinct. In addition, their pairwise comparison revealed significant differences in the expression levels of hoxb1a and hoxb1b genes. Hox gene regulation during embryonic development could give valuable insight into rearing sole broodstocks with different origin in concert, and also into gaining a steady mass production of eggs, either in quality or quantity, all year round.
