The fish consumption has been increasing throughout the world with improved awareness among consumers and culture of fish; an important source of proteinaceous foods for human has become popular during the last few decades in entire Indian subcontinent (Kumar, 2007; Prasad and Kumar, 2007; Saxsena and Garg, 2010). In recent past there has been reports of poor quality fish with high metal conten...

In Greece, up until now, monoculture has been the prevailing fish and shellfish farming system. However, in the last few years, the farmers seek to develop alternative production patterns that could improve the economic performance of their farms through the optimal utilisation of the available resources. The concept of integrated aquaculture is old; however during the last 30 years many author...

This study developed a technique for the preparation of pâté from cachapinta (Pseudoplatystoma sp) waste. For this, frozen minced cachapinta fish was crushed in a mini cutter and homogenized with all other ingredients. The prepared pâté was stored in seamed and thermally treated cans (volume 170 g). Weight proportions of mean moisture, ash, protein, and lipid contents of the minced fish were 75...

Exposure and ecological risks to heavy metals (copper, zinc, manganese, iron) at Lochnivar and Blue Lagoon National Parks in wildlife dependent on the Kafue river contaminated with mining waste was evaluated. Samples included water, fish, grasses and Kafue Lechwe (Kobus leche kafuensis) liver. At both parks copper ranged from 0.03-0.04 mg/l; 3.0-6.0 mg/kg; 11.0-44.0 mg/kg; trace -199.0 mg/kg; w...

Channa punctatus is the most common fish found in Indian rivers and water bodies. The present study was conducted to investigate the dilution effect of tannery waste water on the activity of serum LDH enzyme of the Indian freshwater fish Channa punctatus. The effect was observed based on the result of chronic toxicity and comparison of control with experimental groups. Tannery wastewater causes...

Fish peptone was produced using enzymatic hydrolysis of silver carp filleting by-products by alcalase and trypsin. Also, the efficiency of the hydrolysates as a nitrogen source in Staphylococcus aureus medium was compared with commercial TSB. The results indicated that the protein hydrolysate from alcalase and trypsin had high protein content (92.92%, 91.53 respectively), and degree of hydrolys...

In this paper, we first look into the drawbacks of common technologies, in which Fish algorithm is most famous, used in selective web information gathering systems. For its inherent weakness, Fish algorithm will badly waste end-user time and energy to spider valuable information. We will present a new-kind system, TH-Gatherer system. It makes some important modifications in Fish algorithm, such...

Fish-meal factories generate waste waters with high chemical oxygen demand (COD), suspended solids (SS), fats and protein concentrations. After their treatment by anaerobic digestion, effluents with high ammoniaand organic-nitrogen contents and a fraction of residual COD are produced. A biological nitrification/denitrification process is proposed to reduce both the residual carbon and the nitro...

Collagen is the most abundant protein of animal origin, comprising approximately 30% of total animal protein. There are at least 19 variants of collagen, named type I to XIX. Types I, II, III and V are the fibrous collagens. Type I collagen is found in all connective tissue, including bones and skins. It is a heteropolymer of two "1 chains and one "2 chain. It consists of one-third glycine, con...

Increase in organic waste generation, dwindling nature of global oil reserves coupled with environmental challenges caused by waste oil disposal and burning of fossil fuels necessitated the need for alternative energy resources. Waste cooking oil obtained from the frying fish outlet was analyzed for its physicochemical properties using ASTM D-975 methods. Acid and Iodine values of the oil were ...
