چکیده
Highlight ResearchDipped lamp technology with CCTV (UFLPlus) to catch fish was designed in such a way that the placement of components contained integrated, water-proof, and having good light distribution.The existence new innovated UFLPlus can record events water greatly assist fishing activities fishermen on passive gear as boat charts.UFLPlus worked well increase number hauling every night (from 20-30 kg 50-60 per hauling).AbstractThe usage underwater immersion lights outfitted is technological innovation expected solve inadequacies acoustic work system while also improving existing system. Underwater Fish Lamp Plus attract attention directly monitor condition sea from boat. The purpose this study understand how constructed; test its performance using lamplight, waterproof, tests; learn distribution pattern formed; state catch. separated into two phases: design fabrication UFLPlus, numerous laboratory-scale experiments outdoor trials lift net gear. results reveal performed effectively field after all physical were tested laboratory, values intensity patterns are still accordance level adaptation reception retina. During trial catch, 62 anchovy (Stolephorus sp.), 27 ponyfishes (Leiognathus 32.5 fringe-scale sardinella (Sardinella fimbriata), 17.5 yellow-stripe scad (Selaroides leptolepis) caught. capable functioning an attracts monitors arrival area.

متن کاملApplication of Biofloc technology in aquaculture with an emphasis on ornamental fish
Biofloc technology (BFT) is a relatively new biotechnological means to support high density culture, maintain water quality, biosecurity, reduce the need for water exchange, reutilize the feed and reduce the production cost. This technology is mainly based on the principle of waste nutrients recycling (particularly nitrogen) into microbial biomass that can be used in situ by the cultured animal...
متن کاملFish telemetry and positioning from an autonomous underwater vehicle (AUV)
We assessed telemetry of transmittertagged fishes from an autonomous underwater vehicle with an attached hydrophone/datalogger that procesed code-division-multiple-access acoustic signals. Geolocation estimates used synthetic aperture and relative sound strength mapping. Transmitters could be detected at all angles relative to the AUV heading and as far as 2 km distant. Signal reception pattern...
متن کاملSelenium compounds for fish health: An update
Oxidative stress has become an important subject for terrestrial and aquatic toxicology. The trace element selenium has been demonstrated in chemo-prevention and drug-resistance through reduction of oxidative stress. Selenium compounds could prevent damage to the unsaturated fatty acid of subcellular membranes by lipid peroxidation induced by free radicals in fish.
