“…Alkaline phosphatase is an important enzyme in metabolic processes in animals, including fish (Ram & Sathayanesan 1985), and plays a key role in the digestion, absorption, and transition of nutrients (Swarup 1981;Wu 2018). The observed increase in the enzymatic activity of alkaline phosphatase in the larvae from the AB area ( Figure 2) is consistent with the finding of Das and Majhi (2015) that the activities of metabolic enzymes in fish are increased in response to a low environmental temperature. Moreover, an increase in alkaline phosphatase activity in larval fish may indicate an increase in the synthesis of enzymes in response to cold stress (Yang & Chen 2003;Hassaan et al 2019).…”

Early life stages of marine fish populations may be strongly affected by environmental factors. Changes in the physical environment or the availability of food resources could lead to stress-related physiological responses affecting larval fitness, growth and survival. In the present study, we determined, for the first time, amino acid composition (AAC), lipid, and carbohydrate content, as well as alkaline phosphatase and peroxidase activities in larvae from the European anchovy Engraulis encrasicolus. Fishes were caught in two different spawning areas of the Strait of Sicily, characterized by different environmental conditions, including a coastal upwelling with a lower temperature (Adventure Bank; 20.22 ± 0.38°C) and a thermohaline front with a higher temperature (Maltese Bank 23.10 ± 0.25°C). The results showed that the two groups of larvae, in their early life, had similar nutritional status. However, compared with the samples from the Maltese Bank, the specimens collected in the Adventure Bank area exhibited higher alkaline phosphatase activity, lower concentrations of aspartate plus asparagine, threonine, and arginine but a higher concentration of leucine, highlighting different patterns of amino acid metabolism. Collectively, these results indicated that AAC analysis could represent an additional valid tool to evaluate the link between physiological responses and environmental conditions at early life stages.

“…Water temperature, one of the important abiotic factors, controls various parameters in the life span of teleost fish (Das and Majhi, 2014). Under mid hill conditions at 900 m above msl, we recorded a minimum mean water temperature of 11.2 0 C in January and a maximum of 30.0 0 C during the month of July (Fig.…”

Common carp (Cyprinus carpio Linnaeus, 1758) is an important fish species for aquaculture in the North-east hill region (NEH) of India. However, in recent years, the growth performance of the existing stock of common carp has been a major concern. In an effort to improve fish production from farmers’ ponds and to evaluate the performance of the breed in mid hill condition, a genetically improved breed of common carp, Amur (Hungarian strain) was introduced in Meghalaya in 2010. Fingerlings of Amur common carp (weight ~14.5 g and length ~10.5 cm), reared under mid-altitude conditions in the fish farm of the ICAR Research Complex for North-eastern hill (NEH) Region, Barapani, Meghalaya, attained maturity in about 14 months period. The first breeding trial with this newly introduced variety was conducted successfully in March 2011 when the atmospheric temperature ranged between 16.0-18.30C. The fertilised eggs hatched in 78-83 h (water temperature 19.0-22.80C and pH 6.5-6.8). Three year studies revealed that the performance of Amur common carp is superior over the local existing breed in farmers ponds under the mid hill conditions.

“…In places where mrigal, another carp species, is not consumed due to religious beliefs, L. gonius can serve as an ideal substitute in composite culture setups . Various studies have been conducted to explore different aspects of L. gonius, including induced breeding using pituitary gland extract, Ovaprim, Ovatide, and Wova-FH (Behera et al, 2009 Studies have also explored the possibility of rearing L. gonius using periphyton as a food source (Azim et al 2001) and examined its physiological and biochemical responses under multiple stressors (Das et al 2014). Additionally, research has been conducted on its thermal tolerance limits, oxygen consumption rates (Das et al 2020) and proximate composition (Kumar et al 2013), population structure and genetics (Behera et al 2018), etc.…”

The study investigated the effects of different feeding treatments on the growth, survival, and condition of co-reared Labeo gonius and L. rohita in a cemented tank system (size: 7.25 m X 1.85 m X 0.85 m each). Fish were housed at a density of 10 fish/ m2, maintaining a balanced 1:1 ratio between the two species. Pellet feed (PF) at daily rates of 2%, 4%, and 6% of fish biomass, and conventional feed (CF) consisting of rice bran and mustard oil cake at a daily rate of 2% were compared. The study spanned 60 days and monitored various parameters, including growth, survival, condition factor, hepatosomatic index (HSI), viscerosomatic index (VSI), and monthly water quality assessments. CF-fed fish had a specific growth rate of 0.96% per day, while PF-fed fish showed a range from 1% to 2.9% per day. Survival rates were 84.5% for CF-fed fish and 86.5-91.5% for PF-fed fish. The feed conversion ratio was 1.6 for CF and 1.4-1.45 for PF. PF-fed fish also had higher condition (b>3), HSI ranging from 0.93% to 1.87%, and VSI ranging from 4.1% to 7.6%. L. rohita exhibited better growth, while L. gonius showed higher survival in all tanks. In conclusion, PF is a more beneficial feeding option than CF for co-rearing L. gonius and L. rohita, particularly in hilly environments. It is recommended to administer PF at a rate equivalent to 6% of fish biomass for optimal results. These findings provide valuable guidance for simultaneously rearing L. rohita and L. gonius, facilitating the adoption of appropriate feeding strategies.
