Aquaculture in Punjab is a fast emerging income-generating activity, providing quality and low-cost protein diets to the people. Although fish production of Punjab is relatively less (1.51 lakh tonnes in 2019-20) compared to several other states, the state always topped the country in fish productivity (around 6.5-6.6 ton/hectare), which is more th...

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...

The present study describes about the broodstock management, sexual diamorphism , breeding, and larval rearing of Narayan barb, Pethia narayani under captive conditions. The fish were collected from river Sita, located in Shimoga district, Karnataka, India. The broodstock development was carried out in indoor tanks and brooders were fed with formul...

The freshwater aquaculture activities in Gujarat State, India are mostly carried out in the village ponds leased to the fish farmers through the Village Pond Fisheries policy, 2003. Domestic sewage from households is continuously fed to the village ponds resulting in excessive growth of aquatic weeds. This study describes the effect of aquatic macr...

The various environmental factors have a significant impact on cultured species. One such factor influencing larval production in finfish hatcheries is the tank colour. The current study appraised at how different background tank colours such as white, red, blue, green, and black influenced the growth, survival, and body pigmentation of filament ba...

The natural stock of Trichogaster chuna (Hamilton, 1822) are gradually declining due to destruction of its habitat and over fishing, continuous exploitation of their wild populations might endanger them. This article evaluates breeding performance of honey gourami using different substratum for nest building, embryonic development and larval rearin...

India is blessed with substantial brackishwater fish diversity all along the 8129 km coastline with an estimated potential brackishwater area of 1.24 million ha. The present coastal aquaculture, which is emerging as a significant foreign exchange earner, aims to increase food production for both the domestic and international markets. In recent tim...

The present study compares the diversity and dominance in three undrainable village ponds of Central Gujarat, namely zero-fed, bag-fed and integrated cage cum pond (ICP) aquaculture systems. Qualitative and quantitative analysis of phytoplankton and zooplankton groups was carried out. The phytoplankton and zooplankton data were analysed using the d...

In the earlier COVID-19 Response Series-2 of ICAR-CIFA, aquaculture was credited and informed as a sunrising sector to the audience. Within the sector there are certain enterprises which contributes and attributed as sunrising to the economy. The huge network of hatcheries for fish seed production, feed based farming systems, commercial fish farmin...

Freshwater aquaculture in Gujarat is mainly focussed on village ponds which are leased to the farmers. The state has 6860 village ponds comprising an area of 0.22 lakh ha contributing up to 9% of the inland fish production of the state. The study aimed at evaluating economic analysis of three different types of aquaculture practices viz., zero-fed,...

Catfishes are mainly preferred as edible fishes and are of high demand in commercial market. They also have high sporting value. However, certain species are chosen for aquarium keeping due to their colours, variations and eye catching features. Many of the ornamental catfish species belong to smaller varieties. They are one of the largest groups o...

Kerala is one of the major marine fish producing states of India contributing about 20% of the marine fish landings. FAO Code of Conduct for Responsible Fisheries (CCRF) is a tool which aims to attain sustainability through responsible fishing practices. Evaluation of compliance of marine fisheries of Kerala with provisions of Article 8 (Fishing Op...

This study has been carried out to identify the various stocks of the species, Japanese threadfin bream, Nemipterus japonicus (Bloch, 1791), based on their morphometric characters. Fish samples were collected from four locations, two each from west and east coast of India. Twenty one morphometric distances were measured from each individual and the...

Variation in standard length (SL) and weight parameters based on the selected regression models for Nemipterus japonicus is carried out in this study. Comparison of nonlinear regression model coefficients has executed employing sum of squared reduction test. Fitted models have shown differences with respect to coast, location, sex, locations within...

It is necessary to evaluate the compliance of local fisheries with relevant provisions of the FAO Code of Conduct for Responsible Fisheries (CCRF) which is an indication of how far the code has been implemented. The present study focused on appli-cations of the Code at the grassroot level by local fisheries management authorities in marine fisherie...

The Japanese threadfin bream, Nemipterus japonicus (Bloch, 1791) is a commercially important demersal fish species along the Indian coast especially in the maritime states of Kerala, Tamil Nadu, Maharashtra and Andhra Pradesh. In the present study, 389 samples were collected from four locations Le., Cochin, Mumbai, Kakinada and Chennai and 15 meris...
