The toxicity of ammonia surged with arsenic pollution and high temperature (34 °C). As climate change enhances the pollution in water bodies, however, the aquatic animals are drastically affected and extinct from nature. The present investigation aims to mitigate arsenic and ammonia toxicity and high-temperature stress (As + NH3 + T) using zinc nan...

Anabas testudineus is one of the potential candidates for species diversification in freshwater aquaculture. The present study aimed to evaluate the consumption pattern of endogenous nutritional components available in the form of yolk and digestive enzymes status during early larval development of A. testudineus. The fatty acid profiles viz., satu...

Due to the market instability and increasing demand and prices of fishmeal, the aquafeed industry must seek alternative protein feedstuffs to keep producing aquafeeds in a sustainable and cost-effective way. Hermetia illucens (BSF) larvae meal is considered sustainable since its production recycles organic waste streams into a valuable nutrient. Th...

East Kolkata Wetlands (EKW) is an important site for fish culture in sewage-fed areas, which are major receivers of pollutants and wastages from Kolkata. EKW is internationally important as the Ramsar site was declared on Aug 2002 with an area of 125 km². EKW is a natural water body where wastewater-fed natural aquaculture has been practiced for mo...

The objective of the present study is to evaluate the optimum dietary carbohydrate level of M. gulio fry, which will form the basis for formulating the nutritionally adequate, cost-effective nursery diet. Five iso-proteinous (400 g kg-1 diet) and iso-lipidic (120 g kg-1 diet) semi-purified diets with 100, 150, 200, 250 and 300 g carbohydrate kg-1 d...

Nine semi-purified diets with three different levels of protein (350, 400, and 450 g/kg diet) and lipid (80, 120 and 160 g/kg diet) were fed ad libitum to Mystus gulio fry (0.16 g) in triplicate groups (20 fish/replicate) for 90 days. Flow-through fiber-reinforced tanks (50 L; water flow rate of 0.5 L/min) were used for rearing the fish. Result of...

Arsenic pollution and climate change are two major global challenges that have threatened the aquatic environment and to a certain extent led to extinction of aquatic animals. Concerted and accelerated scientific efforts are in progress to restrict the ill- impacts of pollution and climate change in the aquatic ecosystem. In this context, we have c...

An experiment was conducted for 75 days (5 November 2020 to 21 January 2021) at ICAR-CIFA, Bhubaneswar, Odisha focusing on economic evaluation of Nutrient Film Technique (NFT ) aquaponics system on a pilot-scale mode for rearing puntius (Puntius gonionotus) seed and marigold (Tagetes patula) plant in it. Fish culture tank, biofilter, hydroponics ta...

In the present study, the bioaccumulation of chromium, manganese, cobalt, copper, zinc, selenium, arsenic, strontium, cadmium, tin, antimony and lead in tissues of thirty marine fish species collected from New Ferry Whorf, Sassoon dock and Versova fishing harbour in Mumbai, India, were analysed. The bioaccumulation patterns of these twelve elements...

Aquaculture is the fastest-growing food industry, providing quality protein to the world. To produce the best-quality protein for human use, fish production requires improvements in both quality and quantity, as well as improved food security. Moreover, several abiotic and biotic factors prevalent in aquatic ecosystems, including chemical contamina...

The aquatic ecosystem is one of the largest ecosystems which has several interfering abiotic components impacting aquatic organisms. Climate change and pollution are the main drivers of the abiotic factors; due to such impact, production of fish is tremendously affected. However, a new technology in the form of nano is considered to be a boon for a...

Abstract Climate change impact has disturbed the rainfall pattern worsening the problems of water availability in the aquatic ecosystem of India and other parts of the world. Arsenic pollution, mainly through excessive use of groundwater and other anthropogenic activities, is aggravating in many parts of the world, particularly in South Asia. We ev...

One pilot-scale portable Nutrient Film Technique (NFT) aquaponic system has been designed, developed, and tested at ICAR-CIFA, Bhubaneswar for a period of 90 days (October to December 2018) to study the efficiency of the new design. The experimental setup has three separate units, each consisting of four major components, such as Fibreglass Reinfor...

In the present study, an experiment was carried out to delineate the lethal concentration of (LC50) zinc nanoparticles (Zn-NPs) alone and with concurrent to high temperature (34 °C) in Pangasianodon hypophthalmus. The lethal concentration of Zn-NPs alone and with high temperature was estimated as 21.89 and 19.74 mg/L in P. hypophthalmus. The lethal...

An experiment was designed to delineate the efficacy of a dietary mixture of selenium nanoparticles (Se-NPs) and riboflavin (RF) on the thermal efficiency/tolerance of Pangasianodon hypophthalmus reared under arsenic (2.8 mg/L) and high-temperature (34 °C) stress. A green synthesis method was employed for the synthesis of Se-NPs using fish gills, w...

GROWTH AND PRODUCTION OF PANGAS Pangasius hypophthalmus AND MARIGOLD Tagetes erecta IN FRP MADE NFT AQUAPONICS SYSTEM

Zinc micronutrient is the second most abundant trace element in the animal body, as it could not be stored in the body; hence, regular dietary zinc is required for animals. With this backdrops a 60 days feeding trial was conducted to study the effect of dietary zinc on the thermal tolerance and cellular metabolic stress of Pangasius hypophthalmus r...

Mahua (Bassia latifolia Roxb.) oil cake (MOC) is rich in protein (24%) and energy (19.0 KJ g-1) with high levels of fatty acids comprising saturates (45%), monoenes (42%) and polyunsaturated fatty acids (PUFA, n-6) (7%). Saponin, phenol and flavonoids are the main metabolites. Labeo rohita (Hamilton, 1822) fingerlings (5.25±0.2 g) were fed with fiv...

In world, at present more than 800 million continue to suffer from chronic malnourishment and the global population is expected to grow by another 2 billion to reach 9.6 billion people by 2050. Therefore, it is a huge challenge of feeding the growing population, and at the same time safeguarding its natural resources for future generations. The mic...

The decline of freshwater fish biodiversity corroborates the trends of unsustainable pesticide usage and increase of disease incidence in the last few decades. Little is known about the role of nonlethal exposure to pesticide, which is not uncommon, and concurrent infection of opportunistic pathogens in species decline. Moreover, preventative measu...

A 2-month preliminary study was conducted to delineate the effect of dietary methyl donors (choline, betaine, and lecithin) on the growth performance and metabolic status of Labeo rohita fingerlings subjected to endosulfan alone and in combination with elevated temperature. Four iso-caloric and iso-nitrogenous diets viz. basal diet, betaine-supplem...

A five-week experiment was conducted to delineate stress-mitigating effects of three different methyl donors in Labeo rohita fingerlings subjected to endosulfan toxicity. Four iso-nitrogenous and iso-caloric feed were prepared with and without supplementation of methyl donors. The feed were basal or control diet (i.e., without methyl donor suppleme...
