The study was conducted with the aim to understand the effect of rearing temperatures on juvenile tilapia growth, muscle cellularity and expression of myoD and myostatin genes. Tilapia larvae were reared at 25°C, 30°C and 34°C for 60 days. Fish growth was measured in terms of body weight, white muscle fibre frequency through HE staining and qRT-PCR based expression of myoD and myostatin gene. At 60 day, tilapia juveniles reared at 30°C grew significantly higher than 25°C and 34°C, the frequency distribution of white muscle fibres in diameter class <25 μm was similar at 25°C and 30°C, but was significantly higher for fish reared at 34°C and of white muscle fibre of diameter 25-50 μm was significantly higher at 30°C in comparison to 25°C and 34°C. MyoD gene expression was significantly higher at 34°C than 25°C and 30°C. Whereas, myostatin expression was similar at all three rearing temperature. The present investigation suggests that rearing temperature affects fish growth, muscle cellularity and gene expression in juvenile tilapia. Increase in water temperature to 30°C is beneficial for achieving maximum body growth and hypertrophic muscle growth in O. mossambicus.Not Availabl

Not AvailableOver the years, development of poultry genotypes is driven mainly aiming higher production at optimal temperatures. However, recent increase in extreme heat wave events and enhanced sensitivity of modern poultry genotypes to heat stress has become a major concern leading to significant economic losses to the poultry industry. In India, per capita consumption of poultry meat and eggs is significantly lower than the minimum recommended by Indian Council of the Medical Research and there is need for significant increase in poultry productivity to fulfil these requirements. Conversely, in sub-tropical countries like India where summer is severe, accomplishing higher production under current scenario is a challenge. Earlier intervention strategies including environmental management and nutritional supplementation have been inconsistent in poultry for managing heat stress. Therefore, there is scope for exploring innovative approaches, including genetic marker-assisted selection of poultry breeds for increased heat tolerance and application of molecular techniques in poultry breeding to improve poultry productivity in a sustainable manner. Hence, keeping in view the present situation, it is essential to understand various cellular and molecular mechanisms involved in poultry production including physiological and immunological aspects of the poultry birds under heat stress using molecular biology tools that can help in development of poultry breeds which are better adapted to changing climate.Not Availabl
