The aim of this study was to assess the effect of heavy metal agents on haematological parameter. The Indian major carp Catla catla was exposed to sub lethal concentration of cadmium for various exposure periods7, 14, 21, 28, day haematological parameter on RBC, WBC, and Hg, were measured both in control and experimental fish. During various exposure period’s day. The 7, 14, 21, 28 of RBC, WBC,...

The current investigation was undertaken to study the gill histopathologies due infestation of helminth parasite, monogenetic trematode, Dactylogyrus vastator (Nybelin, 1924) in Indian major carp, Catla catla. There were only symptomatic samples diseased fishes comprised fingerlings and adults catla collected examined. Behaviour respond studied- partial suffocation, lethargic swimming clinical ...

Toll-like receptors (TLRs) and nucleotide binding and oligomerization domain (NOD) receptors are pattern recognition receptors (PRRs) that recognize pathogen-associated molecular patterns (PAMPs) and play crucial role in innate immunity. In addition to PAMPs, PRRs recognize endogenous molecules released from damaged tissue or dead cells [damage-associated molecular patterns (DAMPs)] and activat...

The research investigated the impacts of inclusion of column feeder rohu (Labeo rohita) on growth and production in freshwater prawn-carp-mola polyculture system for a period of 172 days. Four stocking densities of Rohu were maintained as 500, 1,000, 1,500 and 2,000 ha -1 in treatment R500, R1000, R1500 and R2000, respectively in triplicates. All ponds each 120 m 2 were stocked with juvenile fr...

BACKGROUND Probiotic microorganisms are gaining global importance because of their use in the preparation of a nutraceutical or in the treatment of infections. As per the health industry demand, there is an urgent need for exploring new indigenous probiotic strains with its specific origin due to variation in gut microflora, different food habits and specific host-microbial interactions. The ma...

Three species of Indian major carp (Labeo rohita,Catla catla,Cirrhinus mrigala) were collected from local fish market and fishing sites of river Brahmaputra for determining the nutritional value,seasonal variation of proximate composition and vitamin A content of these fishes.Results obtained show that there is no much significant seasonal variations in body composition of Indian major carp tho...

Bisphenol-A (BPA) is a xenoestrogen that mimics the action of natural estrogen, estradiol-17β, and can disrupt the endocrine system. Present study was designed to investigate histopathological effects of BPA on some vital organs of major carp, Catla catla. Fish were exposed to various sub-lethal concentrations (1 to 4 ppm) of BPA in a semi-static system for 15 days. After the stipulated time, l...

A study was carried out on the optimal dose of inorganic fertilizer used in carp polyculture system over a period of 10 months. Three treatments were assigned: without inorganic fertilizer, with the application of 100 kg/ha/month inorganic fertilizer and 150 kg/ha/month inorganic fertilizer as T1, T2 and T3, respectively. Each treatment had three replications. The selected indigenous carp speci...

The present study was conducted to evaluate the effect of traditional Bengal culinary practice on heavy metal content four carp species (Labeo rohita, Catla catla, Cirrhinus cirrhosus, and Hypophthalmichthys molitrix). Fish samples were collected from seven different farms located in Rajshahi district Bangladesh. processed cooked a currying method concentrations five metals (Pb, Co, Cr, Cd, Ni)...
