The transport of live fish is a crucial step to establish fish culture in captivity, and is especially challenging for species that have not been commonly cultured before, therefore transport and handling methods need to be optimized and tailored. This study describes the use of tuna tubes for small-scale transport of medium-sized pelagic fish from the Scombridae family. Tuna tubes are an array...

Fish wastes constitute an important source of biologically active molecules possessing peculiar properties and practical application promises in various areas ( agriculture, medicine, chemistry, biotechnology ). Several enzymes from crustacean and fish wastes for which sizable stocks of viscera are actually available have been considered. These enzyme activities are namely an aminopeptidase fro...

Ensiling as one of the best methods for utilization of tuna wastes was investigated. docosahexaenoic acid [DHA C22:6(n-3)]- rich products were obtained from the wastes (viscera and dark meat) of four tuna species, namely longtail, skipjack, yellowfin and kawakawa by a procedure involving ensiling in organic acids followed by neutralization. Identification of fatty acids in the samples was perfo...

Mascarpone cheese is a type of cheese with high fat content and a mild flavor. These features make this cheese an ingredient commonly used in many and different food products. However, these products usually have high fat and sugar contents. This, coupled with the mascarpone fat content, makes them nutritionally unattractive. This study describes the effect of adding gelatin from marine wastes ...

in this study mercury was determined in canned tuna fish produced and distributed in iran after digestion by the standard methods of aoac. mercury contents in fish and canned tuna fish were determined by cold vapor atomic absorption spectrophotometry. the metal contents expressed in mg/kg wet weight for mercury varied from 0.017 to 0.394 (average of 0. 089) and 0.023 to 0.529 (average of 0.146)...

A marine ascidian-associated bacterium, Halobacillus trueperi RSK CAS9, was optimized for lipase production by response surface methodology using marine waste as substrate. The central composite design was employed, and the optimal medium constituents for maximum lipase production (1355.81 U/ml) were determined to be tuna powder (14.58 g/l), olive oil (5.05 ml/l); NaCl (72.42 g/l), temperature ...

Length frequency data of the longtail tuna, Thunnus tonggol collected from October 2006 to September 2007 were analyzed for evaluation of the stock parameters. T. tonggol is mainly caught by gillnet method. Yearly tuna and tuna-like catches in Iran are of the order of 174,234 mt, close to 46% of which are longtail tuna. The VBG parameters for longtail tuna were: L∞ =133.72cm K=0.35 year−1.The l...

Proteinaceous wastes from the fishery process are an abundant renewable resource for recovery of a variety high-value products. This work attempted to utilize several proteinaceous produce proteases using Streptomyces speibonae TKU048 strain. Among different possible carbon and nitrogen sources, protease productive activity S. was optimal on 1% tuna head powder. Further, casein/gelatin/tuna pow...
