“…Conservation breeding and restocking the natural reserves through large-scale seed production is the need of the hour for sustainable management of golden mahseer. The reduced fitness and survival of captive origin T. putitora in comparison to wild origin larvae [14] , may limit the success of mahseer stock rehabilitation initiatives. In line with the current information available, we investigated the comparative expression of target innate immune genes ( Tptlr2, Tpmyd88, Tpcd36 and Tpil8 ) during the ontogenetic developmental stages of T. putitora obtained from the wild and captive broodstocks.…”

“…Substantial evidences suggest lower fitness and survival of hatchery reared fish when released to their natural conditions [10] , [11] , [12] , [13] . Like in several teleost, the egg quality, larval fitness and survival of progeny from captive-matured golden mahseer brooders were lower as compared to those from wild-collected brooders [14] , which may compromise the success of golden mahseer stock enhancement initiatives. In this context, understanding the innate immune response during the early developmental stages of T. putitora may help in devising management strategies for improving larval fitness and survival during nursery rearing.…”

“…Importantly, a clear characterization of the quality of a larva could not only broaden knowledge on the biological factors and mechanisms influencing the robustness of the progeny but also – by providing a specific “phenotypic marker” – be used to decipher mechanisms affecting gamete quality. Furthermore, it could shed light on the role of spawners in the progeny phenotype and help in developing effective selective breeding programmes, which would be useful for the improvement of the aquaculture industry [5].…”

Background: The larval stage plays a crucial role in the ontogeny of many fish species, leading to profound changes in morphology, physiology and behavior. How larvae face metamorphoses can be associated with their quality, which can vary significantly among the same family or even cohort. This variability depends on the interaction of genetic and nongenetic factors, which are key phenotypic determinants that further affect the overall survival of wild fish and adaptability of cultured stocks. Although researchers and aquaculturists often refer to larvae quality as an important parameter discriminating high- and low-performing stocks, there is currently no universally accepted definition or critically verified set of quality indicators. Therefore, in this study, we generated unique families of Eurasian perch (Perca fluviatilis) larvae to follow their performance during the larval period. Next, we integrated the zootechnical performance data with transcriptomics data from freshly hatched larvae to identify specific molecular quality markers. Results: Zootechnical data revealed statistically significant differences (p < 0.05) in performance between 16 families reared. The RNA-seq data were processed using weighted gene correlation network analysis (WGCNA) and showed particularly significant interactions between gene modules and the length of larvae at the mouth-opening stage, emerging as an important quality-related trait. Next, by comparing the transcriptomic profiles of larvae with high and low lengths at mouth opening, we identified several differentially expressed genes, here chosen as putative larvae quality markers, involved in metabolic processes and antioxidant responses, such as fatty acid desaturase 2 (fads2) and glutathione peroxidase 1b (gpx1b). Conclusions: The findings highlight the length of the larvae at hatching as a valid parameter of larvae quality. Initial length is not just a numerical measurement; it serves as a specific indicator that strongly influences future larval development and survival. 'Longer' larvae appear to benefit from a higher metabolic rate, enhanced antioxidant defenses and a more advanced nervous system. As a result of these insights, we propose genes such as fads2, ctsl1, and gpx1b as potential biomarkers for evaluating larval quality. Our study represents a significant step toward a clear understanding of the factors that determine the quality of fish larvae, with implications for improving aquaculture practices.

“…Fish larval viability depends on broodstock quality (Ciji et al 2022), so it determines the offspring survival rate as aquaculture seeds (Iglesias and Fuentes 2014); similarly, it affects the year-class strength of its wild population (Bergenius et al 2002). Glass eels that encounter the Cimandiri Estuary are partly caught to meet the needs of eel culture seeds, whereas the rest probably become recruits, increasing the individual number and biomass of its natural population.…”

Glass eel viability determines the success of cultivation and governs the recruitment variability, as seeds in aquaculture and its wild population, respectively. This study aims to examine the quality of glass eel using biometric measurements coupled proximate contents. Glass eel collection was made montly by using lift-net like fishing gear in Cimandiry Estuary during December 2020 - April 2021. Biometric aspects were examined on length, weight, eye diameter, heart, and liver, whereas proximate was run on proteins, fats, carbohydrates, and ash. The results showed that length and weight steadily increased between month, though the condition factor was indifferent. Eye diameter and mouth opening confirm the vision of diurnal predatory fish. Heart and liver have demonstrated the metabolism capability and fast swimming fish favors to migratory catadromous fish. Proteins, fats, carbohydrates, and ash fluctuated between month, though insignificant between month comparison. No clear confirmation of proximate analysis on biometric characters. However, the glass eels with largest size in April might be best for aquaculture.
