anzali lagoon can be one of the most important wetlands called the world. this lagoon to support the most fish in the caspian sea is reproduced for the spawn, multiply, and sometimes live, to make the pond.much of rasht and anzali city sewage and agricultural waste area of the lagoon through rivers into the pyrbazar and increased levels of organic pollutants such as nitrite, nitrate, phosphate,...

Introduction Seafoods are inherently functional and possess many components that are good for human health. Seafoods and their by-products are an excellent source of nutraceuticals and bioactives, and these can be extracted/isolated and added to a range of foods thereby enhancing functionality of the foods in terms of human health (Shahidi, 2003; Alasalvar and Taylor, 2002). These aspects are a...

A flow system was developed for the determination of total mercury concentration in fish samples by cold vapor atomic absorption spectrophotometry (CVAAS), based on the multicommuted flow injection analysis (MCFIA) approach. The system uses independently controlled solenoid valves for the introduction of reagents and samples. When not injected, solutions were recirculating to the reservoir bott...

Arthropod development can be used to determine the time of colonization of human remains to infer a minimum postmortem interval. The black soldier fly, Hermetia illucens L. (Diptera. Stratiomyidae) is native to North America and is unique in that its larvae can consume a wide range of decomposing organic material, including carrion. Larvae development was observed on six resources: control poul...

An experiment on integrated walking catfish-tilapia culture was conducted for 5 months. The walking catfish were stocked at 400 and 800 fish/cage in two 4-m nylon cages, which were suspended in each of two 250-m earthen ponds. Sex-reversed male tilapia (Oreochromis niloticus) were reared at 1 fish/m2 in the open pond. Whereas the catfish were reared with supplemental feed, tilapia were solely d...

present communication deals with the study of four village fish culture ponds (two wild and two managed ponds) from district hisar of haryana, india was undertaken, to correlate the water quality and biological cycles in ponds with fish production. studies have revealed that the ponds are in good trophic status. chlorides, total hardness, calcium, magnesium, biochemical oxygen demand (bod), pho...

the experiment was conducted on forty five broiler chickens at 4 weeks of age, for a period of threeweeks, to assess the effect of complete replacement of fish meal with processed fish wastes (fish waste acidsilage and surimi waste powder) on the blood protein, lipid and antioxidant status in broiler chicken, eventhough an earlier study indicated that this replacement induced normal growth rate...

Around 10% of the global fish catch (>90 million tonnes) is currently discarded, while by-products in fisheries account for up to 70% whole weight. From these, bones and scales represent 14–20% by-products, which are also discarded. Therefore, there an unmet need valorising these by transforming them into functional nutritious ingredients. Towards this objective, we report herein different culi...
