Green Energy from Discarded Wool and Fish Scales

Waste and Biomass Valorization, 2021
Proteins in discarded wool and extractants obtained from fish scale dissolved in NaOH solution can be used as electrolytes in a biochemical fuel cell that can generate up to 418 mV of energy. Discarded wool and fish scales are raw materials that are available in large quantities at low cost but generally disposed as waste. Both fish scales and wool are

Reducing discards of fish at sea: a review of European pilot projects

Journal of Environmental Management, 2010
This paper is about improving the viability of discard-reduction pilot projects. One way to address the problem of wasteful discarding of fish at sea is to initiate pilot projects to trial potential solutions, such as selective gear, area closures, discard bans and data enhancement, which could subsequently be adopted by the fishing industry, either ...

Discarded fishing net pollution in coastal areas of Bangladesh

Science of The Total Environment
Discarded fishing nets, a major source of marine litter, significantly threaten the marine environment and contribute to plastic pollution due to the synthetic polymers they contain. Though Bangladesh is a maritime country with 0.5 million of fishers dependent on coastal and marine fishing, there have been no studies to date on the plastic pollution ...

Bycatch and discard fish in the japanese fisheries

2004
Abstract Discards of bycatch in fisheries is one of the most serious concerns in fisheries management. The types of discarded fish from Japanese fisheries can be mainly classified into four categories: 1) species with low value or no value in the market, 2) small sized species including young or juvenile, even if they have commercial values as adult,

Fishing suitability maps: helping fishermen reduce discards

Canadian Journal of Fisheries and Aquatic Sciences, 2015
Discards poses a serious problem for the productivity and sustainability of European fisheries and thus is an important fisheries and ecological management issue to be solved. In this paper we present a statistical tool, based on the random forest technique, that aims to reduce the negative ecological impact of fishing by providing fishermen with near-

A comparison of methods for onboard sampling of discards in commercial fishing

Fisheries Research, 1999
Two methods for onboard sampling of discards practised in UK waters are compared. The fishing gear was light trawl and the principal species caught were haddock and whiting. The quantities of fish discarded, as well as those for the market, were measured. The methods for onboard sampling of discards were carried out in parallel.

Scavenging by fish of discards from the Patagonian squid fishery

Fisheries Research, 1999
Abstract Stomach contents of six fish species which are typically taken as bycatch in the squid fishery on the Patagonian shelf and slope were examined. Squid remains discarded by the fishery represented some 20–40% by volume of the diet of Merluccius hubbsi , Patagononotothen ramsayi and Macrourus holotrachys .

Key principles for understanding fish bycatch discard mortality

Canadian Journal of Fisheries and Aquatic Sciences, 2002
The mortality of discarded fish bycatch is an important issue in fisheries management and, because it is generally unmeasured, represents a large source of uncertainty in estimates of fishing mortality worldwide. Development of accurate measures of discard mortality requires fundamental knowledge, based on principles of bycatch stressor action, of why
