Maximum Sustainable Yield= the maximum level at which a natural
resource can be routinely exploited without long-term depletion.
Currently we are exploiting our fish stocks to such an extent that experts expect that the fishing industry will collapse by 2050!

Gill Nets
Gill nets are vertical panels of netting normally set in a straight line.
Fish may be caught by gill nets in 3 ways :1. wedged – held by the mesh around the body 2. gilled – held by mesh slipping behind the opercula3. tangled – held by teeth, spines, maxillaries, or
other protrusions without the body penetrating the mesh.
Mesh size, twine strength, as well as net length and depth are all closely regulated to reduce bycatch of non-target species.

Purse Seine NetsA purse seine is a large wall of netting
deployed around an entire area or school of fish.
The seine has floats along the top line with a lead line threaded through rings along the bottom. Once a school of fish is located, a skiff encircles the school with the net. The lead line is then pulled in, "pursing" the net closed on the bottom, preventing fish from escaping by swimming downward.

Trawling
![Page 18: Pg. 92 RTW: What is one problem caused by invasive species? Objective: I will be able to describe the consequences of biodiversity due to invasive species.](https://reader035.fdocuments.in/reader035/viewer/2022081521/5a4d1b957f8b9ab0599c338c/html5/thumbnails/18.jpg)
TrawlingTrawls are nets towed behind a boat to
collect organisms. Trawls can be divided into three categories
based on where they sample the water column: 1. Surface2. Midwater3. Bottom

Long Lines
![Page 20: Pg. 92 RTW: What is one problem caused by invasive species? Objective: I will be able to describe the consequences of biodiversity due to invasive species.](https://reader035.fdocuments.in/reader035/viewer/2022081521/5a4d1b957f8b9ab0599c338c/html5/thumbnails/20.jpg)
Long LinesLong lines use a long line, called the
main line, with baited hooks attached at intervals by means of branch lines called snoods.
Longlines can be set to hang near the surface (pelagic longline) or along the sea floor (demersal longline)

Drift Nets

Drift NetsDrift nets hang vertically in the water
column without being anchored to the bottom.
The main difference between gill nets and drift nets is whether or not they are anchored to the bottom.

Problems with Fishing MethodsBycatch= the unwanted fish and other
marine creatures caught during commercial fishing for a different species.
Trawling methods can damage coral reefs and other ecosystems
Unsustainable
![Page 25: Pg. 92 RTW: What is one problem caused by invasive species? Objective: I will be able to describe the consequences of biodiversity due to invasive species.](https://reader035.fdocuments.in/reader035/viewer/2022081521/5a4d1b957f8b9ab0599c338c/html5/thumbnails/25.jpg)
Solutions?Reduce bycatch with alternative gear (turtle exclusion hatch or circle hooks)Use sustainable methodsAquaculture= raising fish similar to livestock
