This section defines a 'trawl net' as a type of fishing net shaped like a cone or funnel that is pulled through the water by a boat. Any gear attached to the net is included in this definition. The use of these nets must follow specific federal regulations for catching groundfish, unless stated otherwise in related laws.

This law makes it illegal to use a trawl net with mesh sizes smaller than 4.5 inches, unless specific exceptions are mentioned within this article or in federal groundfish regulations under the Magnuson Fishery Conservation and Management Act.

This law states that trawl nets and Chinese shrimp nets can be used in the waters inside the Golden Gate Bridge to catch certain types of fish such as shrimp and a few specific fish species. However, this activity must follow regulations set by the commission.

This law prohibits the possession of trawl nets or dragnets in certain California fishing districts (specifically, Districts 4, 19, 19A, 20, 20A, and 21). However, there is an exception that allows these nets in Districts 4, 19, 19A, 19B, and 21 if specific regulations set by the commission are followed.

This law states it's illegal to have more than 500 pounds of crabs on any boat equipped with or using any kind of trawl or drag net.

This law makes it illegal for anyone to have salmon on a boat or bring salmon to land if they have any kind of trawl net on board. However, if you catch salmon by accident while catching other fish with a trawl net, you can keep and bring the salmon to land if you have specific authorization. This authorization can come from federal regulations, a permit from the state department, or both.

This law prohibits anyone on a boat with trawl or drag nets south of a line from Point Reyes from catching or having Dungeness crab. It also stops Dungeness crab from being moved to another boat.

This law states that in Districts 6, 7, and 10 in California, you can use trawl nets only in waters that are at least three nautical miles away from the nearest mainland shore.

This law allows the use of trawl nets in Districts 17, 18, and 118.5, but only in areas at least three nautical miles away from the mainland shore. This rule also covers parts of Monterey Bay, Estero Bay, and San Luis Obispo Bay that fall within these districts.

This law makes it illegal to use or have a trawl net with more than one layer in the bag or cod-end part, unless there's special permission under Section 8496 or from the commission.

This California law allows the use of chafing gear in fishing nets. However, the gear cannot be attached directly to the closed end of the net. Unless allowed by federal rules under the Magnuson Fishery Conservation and Management Act, all chafing gear should have a mesh size of at least six inches, except if it's covering only the bottom half of the net, where the mesh size can be any size.

This law gives the commission authority over certain state-managed bottom trawl fisheries not covered by federal or state management plans, aiming for sustainable management and ecosystem protection, particularly if bottom trawling is harmful. It specifically manages fisheries for California halibut, sea cucumber, ridge-back, spot, and golden prawn, and pink shrimp. All commercial bottom trawl vessels must adhere to federal groundfish observer program policies. Additional fishing areas can only be approved if scientific evidence shows sustainability and minimal habitat harm.

Fishing with roller gear over eight inches is illegal. A bycatch reduction device is required for prawn or pink shrimp fishing. Bottom trawling in state waters is mostly prohibited, except under certain conditions. Scientific research is exempt from these restrictions. The commission is tasked with helping convert bottom trawling to more sustainable methods and cannot issue new permits for trawlers retired through conversions. Vessels need a permit to use bottom trawling equipment.

This law outlines the rules for using trawl nets to catch shrimp and prawns in certain areas of California waters. You need a special permit to use these nets, and specific areas are defined where trawling is allowed. Before 2008, trawling in specific areas could be done at a distance of at least two nautical miles from shore, but this was only temporary. For pink shrimp, there are strict limits on how much of other types of fish you can accidentally catch (bycatch) and land, except for certain species, with no Pacific halibut allowed. The commission can allow closer trawling if they determine it won't harm the environment or fish habitats. They have to check that the trawls reduce bycatch and don't damage the ocean floor or impede habitat restoration.

This law makes it illegal to use a trawl net with a mesh smaller than 7.5 inches in waters located between one and three nautical miles from the mainland shore, specifically between Point Arguello and Point Mugu. The net's cod end must also be at least 29 meshes long and 47 meshes in circumference.
