Andhra Pradesh is endowed with a wealth of water resources including rivers, canals, reservoirs, ponds and tanks, two large estuarine systems (Godavari and Krishna), backwaters near Kakinada and Visakhapatnam. These water bodies are home to a rich biodiversity of ichthyofauna. Among, these natural resources a diverse and unique group of fishes are...

A thorough examination of Ichthyofaunal diversity was carried out in the Godavari River in Andhra Pradesh from February 2022 to July 2023. The samples were identified up to the species level using standard taxonomic approaches such as morphometric, meristic, and descriptive features. A total of 88 fish species were reported in the six selected land...

This study was undertaken during 2022 in the Regional Research Center of ICAR-Central Institute of Freshwater Aquaculture, Anand, Gujarat, India to study the present status and potential in the development of freshwater aquaculture in the state of Gujarat. The present seed production (2608.37 million fry) and Inland fish production (0.158 MT) in Gu...

A feeding trial was carried to assess the cost effective diet for giant freshwater prawn (Macrobrachium rosenbergii) in earthen pond (0.02 ha) for 180 days. Control and experimental diets were prepared with 30% crude protein each using the locally available cheaper protein sources viz., sunflower oil cake, sesame oil cake, palm karnel cake, meat an...

भारत देश में मत्स्य पालन क्षेत्र ने फसल और पशुधन क्षेत्रों की तुलना में उच्च वि कास दर दर्ज कि या है और इसके साथ देश की आर्थिक रूप से कमजोर आबादी के एक बड़े वर्ग की आजीवि का में भी योगदान देता आ रहा है। हमारे देश का मत्स्य उत्पादन, 1991-92 मे 41.57 लाख टन (समुद्री के क्षेत्र से 24.47 लाख टन और अंतर्देशीय क्षेत्र से 17.10 लाख टन) से बढ़कर 2019- 20 म...

Carbon footprint analysis for different freshwater aquaculture practices in different states of India along with Bay of Bengal was done. In West Bengal, the average inputs as carbon equivalent (CE) were [Formula: see text][Formula: see text]kg/ha with an average output of [Formula: see text][Formula: see text]kg live weight/ha. In Odisha, the input...

In spite of vast diverse fish genetic resource of India, several exotic species have been introduced into India. Chinese carps which were introduced in India with an objective of increasing the yields in aquaculture has paved way for composite fish culture in India. Introduction of exotic species for fisheries and aquaculture was successful in some...

Six purified diets were formulated to determine the optimum dietary lipid levels of pengba, Osteobrama belangeri juveniles. Experiment trials were conducted for 60 days to evaluate growth performance, total lipid, lipase activity and fatty acids by inclusion of fish and sunflower oil (ratio 1:1) in the diet. The dietary lipid level showed a signifi...

The Green House Gas Emission (GHGs) from the carp culture ponds (n = 12) of West Godavari, Krishna, and Guntur districts of Andhra Pradesh and from the ponds (n = 4) of Moyna, East Medinipur district of West Bengal, India was assessed through carbon storage and carbon footprint analysis. The average inputs as Carbon Equivalent (CE) were 14407 ± 265...

Aquaculture has been recognized as instrumental in generating income and rural employment besides stimulating growth of a number of ancillary industries. It has increased manifold in Andhra Pradesh in recent times in comparison to agriculture as it brings more profit and requiring less labour per unit area. Outbreak of coronavirus has not only disr...

Aquaculture has become the fastest growing sector of food production in the world. Despite the encouraging trends, several constraints have negative impact on the growth of aquaculture in India as in other parts of the world. In the present survey it was observed that except in some parts in Andhra Pradesh, the farmers involved in aquaculture are m...

We surveyed the fish farmers of five states, viz. Andhra Pradesh, Karnataka, Gujarat, Odisha and West Bengal of India for adaptation and mitigation strategies of climate change impact in freshwater aquaculture. In monsoon period especially when the cyclone occurred, overall 9% fish farmers responded regarding fish migration from one pond to another...

Pengba, Osteobrama belangeri (Valenciennes, 1844) is considered as one of the candidate species for diversification of aquaculture. However, only scanty information is available on its nutrient requirements. Hence, the present study was conducted on growth and digestive enzyme activities of pengba fry in response to different dietary protein levels...

Survey was performed to assess the availability and use of different commercial grade aqua-medicines, drugs and chemicals in aquaculture activities in the selected key districts of four aquaculture dominant states of India viz., Andhra Pradesh, Odisha, Jharkhand and Chhattisgarh. A total of 265 farms, 36 aqua shops, and 18 drug manufacturer units w...

Indian fisheries and aquaculture is an important sector of food production, providing nutritional security to the food basket, contributing to the agricultural exports and engaging about fourteen million people in different activities. With diverse aquatic resources the country has shown continuous and sustained increments in fish production since...

Pengba is one of the most potential candidate fish species for aquaculture and an ideal fish species for diversification of carp culture due to its better taste and meat quality. In order to develop its culture technique, feeding of early stages has to be evaluated. The study was conducted to evaluate the effect of co-feeding of pengba larvae with...
