“…Stronger temperature influences during early ontogeny could be due to weaker selection at this stage when yolk resources are plentiful. However, increasingly strong selective pressures should occur as larval fish enter the high mortality life‐history stage around first feeding when yolk resources have been exhausted (Aral et al, 2011; Jørgensen & Holt, 2013; Pechenik, 2006; Sifa & Mathias, 1987). Therefore, environmental robustness in response to temperature variation would be favored to maintain growth and mortality rates (Jones et al, 2003).…”

Environmental conditions can impact the development of phenotypes and in turn the performance of individuals. Climate change, therefore, provides a pressing need to extend our understanding of how temperature will influence phenotypic variation. To address this, we assessed the impact of increased temperatures on ecologically significant phenotypic traits in Arctic charr (Salvelinus alpinus). We raised Arctic charr at 5°C and 9°C to simulate a predicted climate change scenario and examined temperature‐induced variation in ossification, bone metabolism, skeletal morphology, and escape response. Fish reared at 9°C exhibited less cartilage and bone development at the same developmental stage, but also higher bone metabolism in localized regions. The higher temperature treatment also resulted in significant differences in craniofacial morphology, changes in the degree of variation, and fewer vertebrae. Both temperature regime and vertebral number affected escape response performance, with higher temperature leading to decreased latency. These findings demonstrate that climate change has the potential to impact development through multiple routes with the potential for plasticity and the release of cryptic genetic variation to have strong impacts on function through ecological performance and survival.

“…The egg hatching and larval rearing up to yolk sac absorption was undertaken up in the same tank that was used for spawning. In the present study, the developmental stages were divided into embryonic and larval development up to yolk sac absorption and were examined randomly under a light microscope with a digital camera, Nikon ECLIPSE E100, (Aral et al, 2011) and measured using ocular micrometer. The embryonic stage was considered when the development occurs inside the egg shell and ends at the hatching.…”

The study describes, for the first time, captive breeding, embryonic and larval development of Barilius bendelisis. The captive breeding trial was carried out in April, in fish farm of Directorate of Coldwater Fisheries Research (DCFR), Bhimtal, India using differnet doses of ovatide. The most appropriate dose of ovatide was reported to be 0.3 ml/kg body weight to males and 0.6 ml/kg body weight to females. Fertilized eggs measuring 1.4-1.7 mm were spherical, demersal, and transparent with dark yellow coloured yolk. Hatching occurred 140 -160 hours after fertilization at 19.09°C ± 0.395. Newly hatched larvae were transparent with yellowish yolk reserve, measuring 5.57 - 6.71 mm in total length and characterized by pigmented eye and yolk sac which completely absorbed in 72 hours.

“…The length of the time changes from species to species. It varies according to species, by shape, size, body ratio, fin size, pigmentation across different sizes and orders, shape, and time of the organ formation in the postlarval stage (Aral et al, 2011). Thus, information on the early larval stage of the fishes is needed for increasing the larval growth and maximizing survival.…”

This study was conducted to investigate the biological development and growth of the Amur catfish, Silurus asotuss at the early larval stage. The eggs and larvae were obtained via the artificial spawning technique. The findings showed that the eggs of the Amur catfish hatched 27 hr after fertilization (hAF) under temperature conditions of 26.9 ± 1.3°C. The newly hatched larvae (4.71 ± 0.87 mm) had a large green yolk sac (0.99 ± 0.02 mm3), unpigmented eyes, undeveloped mouth, and closed anus with one pair of developed maxillary barbels. At the 30 hAH (7.01 ± 0.41 mm), the yolk sac continued to decrease (0.33 ± 0.08 mm3), the barbels elongated, the mouth opened, the lower jaw was movable, with the peristaltic movement of the small intestine detectable. At this point, the larvae started to feed on rotifer and formulated feed. At 72 hAH, larvae (9.02 ± 0.86 mm) had developed pectoral and dorsal fin and at 12 dAH (34.10 ± 0.89 mm) and entered the juvenile stage. This study concluded that the larval development and growth of the Amur catfish is relatively comparable to other tropical catfishes hence similar rearing techniques can be adopted to enhance the overall growth performance at the later stages
