Aquaculture, as its name entails, involves the cultivation of fish (such as carp, salmon, trout, etc…), crustaceans (such as shrimps or crabs), mollusks (such as oysters or mussels) and aquatics plants in a constrained environment. | Aquaculture, as its name entails, involves the cultivation of fish (such as carp, salmon, trout, etc…), crustaceans (such as shrimps or crabs), mollusks (such as oysters or mussels) and aquatics plants in a constrained environment. | ||

As its name indicates, Capture fishery refers to various practices involving the capture/harvesting of naturally occurring living resources in both marine<ref>Open seas, coastal regions, inland seas, etc…</ref> and freshwater<ref>Lakes, rivers, ponds, streams, etc…</ref> environments. If the industry involves the capture of finfish<ref name=Finfish />, mollusks and crustaceans, the largest part of its yield consists of finfish. Indeed, as capture fishing's most productive practices rely on draging or setting nets in open waters, swimming finfishs will have a much larger chance of getting caught than any other species. | As its name indicates, Capture fishery refers to various practices involving the capture/harvesting of naturally occurring living resources in both marine<ref>Open seas, coastal regions, inland seas, etc…</ref> and freshwater<ref>Lakes, rivers, ponds, streams, etc…</ref> environments.

Hard fishing, also refered to as “dragging arts”, relies on boats dragging nets behind. Called trawlers, these fishing boats call on a heavy use of petrol and only allow a rough selection of the species they capture as they scrape waters at a large scale. If the depth of the fishing method may vary, nets are more than often ballasted with heavy weights which have a destructive impact on the seabed and marine biodiversity as they can violently come in contact with rocks and wild species. | Hard fishing, also refered to as “dragging arts”, relies on boats dragging nets behind.

==== <u>Capture fishery involves a very large percentage of waste</u> ==== | |||
Despite improvements in fish processing and distribution practices, loss or wastage between capture and consumption still accounts for an estimated 27%<ref name=FAO /> of landed fish. In 2011, it was estimated that the food loss and waste of the whole fishing sector amounted to 35% of global catches, with between 9 and 15 percent of these losses due to “hard” fishing technics, hurting fish populations with equipment or throwing injured fish back into the sea. But trawlers are not the only ones to blame: loss and waste are found along the whole value chain, from production to the consumer. | |||
