Remote alpine lakes do not receive any direct aquatic inputs from anthropogenic activities. Therefore, these ecosystems may receive persistent organic compounds (POPs) by direct atmospheric deposition, only. Consequently, fish dwelling in these ecosystems represent an excellent indicator for the long-term atmospheric input of bioaccumulating and persistent contaminants. In the present study, fi...

The monitoring of farming processes can optimize the use of resources and improve its sustainability and profitability. In fish farms, the water quality, tank environment, and fish behavior must be monitored. Wireless sensor networks (WSNs) are a promising option to perform this monitoring. Nevertheless, its high cost is slowing the expansion of its use. In this paper, we propose a set of senso...

Neoplasia in fish can result from contamination of waters with carcinogens and promoters. Cancer in fish, therefore, is a possible indicator of cancer risk to man and serves as a guide to the need for preventive approaches involving improved means of waste disposal and environmental hygiene. Moreover, cancer in fish indicates that this important food source may be contaminated. Detection of gen...

Fish sarcoplasmic protein (SP) is currently dumped as waste from surimi industry and its recovery by practical method for being the non-meat ingredient in meat industry would be a strategy to utilize effectively the fish resource. This study was aimed to apply pH treatment for fish SP recovery and evaluated its effect on pork myofibrillar protein (MP) gel. The pH values of fish SP were changed ...

Title of Document: A NOVEL APPROACH TO PRODUCE ORGANIC FERTILIZER FROM FISH SCRAPS Armin Norouzi, Master of Science, 2013 Directed By: Y. Martin Lo, Ph.D., Department of Nutrition and Food Science A process was developed using an acidic system to hydrolyze fish protein, followed by a membrane-based separation process to purify and separate the desired liquid portion from the remaining solid pri...

Abstract Fish cultivation is one of the ways to increase productivity fishery technology development. Technology innovation in Indonesia has existed since long ago, especially Lampung province. The technological development trout makes business more effective, efficient, economical, highly competitive, and environmentally friendly. This research aimed identify plus value fish that economic valu...

Many studies about endocrine pollution in the aquatic environment reveal changes in the reproduction system of biota. We analysed endocrine activities in two rivers in Southern Germany using three approaches: (1) chemical analyses, (2) in vitro bioassays, and (3) in vivo investigations in fish and snails. Chemical analyses were based on gas chromatography coupled with mass spectrometry. For in ...

In this paper the extraction of oils from trout waste is investigated. Trout heads, viscera and spine, obtained from a fish-processing company, have been separately freeze-dried and then extracted. Two different solvent extraction techniques have been utilized and compared: the common soxhlet extraction, which utilizes n-hexane at atmospheric pressure as solvent, and the supercritical CO2 extra...
