the histological analysis, disposition and histochemical localization of tryptophan were investigated in the pancreas to compare the cellular organization and histochemical characterization in the pancreas of labeo rohita (hamilton, 1822), mystus vittatus (bloch, 1790) and notopterus notopterus (pallas, 1769) having different feeding habits. histological analysis demonstrated that the exocrine ...
Organisations face many threats that coarsely can be separated in inside threats and outside threats. Threats from insiders are especially hard to counter since insiders have special knowledge and privileges. Therefore, malicious insider actions are hard to distinguish from benign actions. After discussing new definitions of insiders and insider threats, this article gives an overview of how to...
Sex identification is linked to sexual dimorphism and an important study issue in fish biology aquaculture. However, owing the unmarked heteromorphism between adult Hemibarbus labeo, it often difficult distinguish their sex by visual observation. This aimed find a simple reliable morphometric criterion for of H. labeo using discriminant models. Forty-two traits sixty-eight individuals collected...
The objective of the present study was to investigate trace metal levels of different varieties of fresh water fish using Inductively Coupled Plasma Mass Spectrophotometer after microwave digestion (MD-ICPMS). Fish samples were collected from the outlets of twin cities of Hyderabad and Secunderabad. The trace metal content in different varieties of analyzed fish were ranged from 0.24 to 1.68 mg...
Sublethal effects of cypermethrin and carbofuran on hematological parameters and their complete recovery were studied in Labeo rohita as a function of exposure time. Exposure of Labeo rohita to sublethal levels of cypermethrin and carbofuran resulted in significantly (P<0.05) lower values for erythrocyte count (RBC), hemoglobin content (Hb), and hematocrit compared with the control group. In co...
The erythrocyte abnormality test was analyzed in kidney cells of freshwater fish, Labeo rohita exposed to tannery industry effluent. The 96h LC50 value of tannery effluent against fish was calculated by Finney method and it comes out to be 7.07%. Three sublethal concentrations on basis of 96h LC50 value (3.53%, 1.76% and 0.88%) were selected. Fishes were exposed to these concentrations for 24h,...
The fish is an important food stuff and source of protein all over the world. In Bangladesh, fisheries sector contributes a lot, in the case of the earning foreign currency and meeting domestic need of the animal proteins. To fulfill the domestic need of protein and fish, Bangladesh imports fish and fish products from the neighboring county. In many studies, it was proved that most of the impor...
Atrazine (2-chloro-4-ethylamino-6-isopropylamino 1,3,5-triazine) is a widely used selective herbicide. Due to its persistence, it is present in the surface waters, contaminating non-target organisms such as fish. Herbicide atrazine was administered to Labeo rohita fingerlings in 120 hours. The used dose of atrazine was 0.18 mg/l for 120 hours (LC ). The histopathological changes in the gill tis...
as new pathogenic strains are emerging and threatening aquaculture development, myxosporeans (myxozoa) are receiving much attention in recent years. myxosporean taxonomy is traditionally based on morphology of the myxospore stage. molecular data on indian myxosporeans are rare. in this report, the 18s rrna gene sequence of myxobolus cuttacki infecting gill lamellae of minor carp labeo bata (ham...
