Fish and Law: The Legality of Fishing


NMFS Patrol


California DFG Warden Badge



NMFS Office of Law Enforcement


Many of you were asking about what it means for there to be a "legal" size for a fish or invertibrate cought for sport or commercially. This is a little description of the laws put in place to protect our environment (and marine life populations), how they are created, who enforces them, and the punishments for violations. If any of you have been fishing, you know that once you turn 16, you need to purchase a fishing license for all fishing (freshwater and saltwater), except if you are fishing off of a pier. These licenses are issued by the California Department of Fish and Game. Every state has one of these agencies .

These wildlife resource agencies protect the wild populations of fish and hunted animals, and regulate the numbers taken so their populations continue to thrive. These agencies protect against poachers, polluters and inspect commercial fishing vessels to protect the environment. An officer of the DFG or Department of Fish and Game is known as a "Warden". They are fully certified peace officers, carry a gun and even respond to aid other law enforcement agencies. In state parks and in protected wildlife areas, they can even issue traffic citations. The revenues from the licenses go to marine research, wildlife research, and to help fund the wages/expenses not covered by California's budget. The laws enforced by DFG are created by the California Fish and Game Commission and ratified at the capitol. All of these laws are designed to protect endangered or threatened species, and to ensure that the environment is not being harmed in any way. They make sure that there are enough of all species for future fisherman and commercial enterprises. Periodical scientific research is conducted to survey the populations of various species. DFG also runs fish hatcheries to reintroduce damaged populations back into the wild and help a new population start.

The California DFG enforces many laws ranging from the size of animals caught/hunted (certain sizes are prohibited due to the age of the animal and reproductive state) to how many hooks can be on one line. These regulations can be found in any bait/tackle or sports store and they cover all regulations. There are regulations for all kinds of animals, game (birds/mammals), molluscs (squid, octopus, clams, mussels, abalone, sea urchins) and fish. They also permit special licenses for kelp harvesting, abalone diving/farming and commercial fishing. The Garibaldi (our state fish) is prohibited to catch as well as the Giant Black Sea Bass. Violations are very strict and are taken seriously. Fines are most commonly issued but every citation is a Misdemeanor violation and requires a visit to court. Fines are very high, especially since the DGF's revenue was cut due to the budget crisis. In some cases, depending on the warden and judge, jail time is used as a sentence. All violations are punishable by jail time but fines are most common. For a list of fines, you can visit the law enforcement page of the DFG at http://www.dfg.ca.gov/.

There are also federal law enforcement agencies that inspect commerical and recreational fishing vessels in marine protected areas as well as in ports/airports (smuggling species in to the country even as a pet is a federal offense). These agencies are associated with the National Marine Fisheries Service (NMFS) and the U.S. Fish and Wildlfe Service. These inspectors and enforcement officers are federally trained Special Agents.

PICTURES LINK NOW FUNCTIONAL!!!

I am pleased to inform you that our pictures link is up and running.  There are still some kinks to be worked out but photos from Abalone Cove ARE posted, they are on page three (3).  I will be adding more photos soon.  Currently, the reef photos are from Ras Mohammed National Park as well as Sharm El-Sheikh in Egypt.  Enjoy!

MYSTERY FISH ?????


Hello again. I have been hard at work trying to identify the "Mystery Fish" found at Abalone Cove on the 3/9/09 field trip (Marymount College Sci. 160 Spring '09). This fish was found in the mid-low intertidal zone on the bottom of a rock. This fish appeared to be a juvenile ray since it had no scales and an arrow shaped body (bigger rounded head). It was slimy but had one perplexing aspect. It had fully developed opercula (gill flaps) and appeared to be able to survive without any trouble outside of the water. This fish also had dorsal and caudal fins, a sign that begins to spell out doom for the ray theory, since none of the local rays had any structures like this. The answer was found in "Life Between The Tides", by Jeffrey Brandon and Frank Rokop (1985).  This amazing little guide unveiled the mystery for us.  The fish seen here is a California Clingfish, Gobiesox rhessodon.  Compared to its close relative, The Northern Clingfish (Gobiesox maeandricus) it is relatively uncommon because it prefers safe areas under rocks.  The Clingfish are a family of fish that are named because they have a ventral sucker (ventral means underside or belly) that is used to "cling" to rocks, substrates or even other fish.  The California Clingfish has a sheath-like tissue covering so that it can cover the sucker when its not fixed.   In the intertidal zone, the sucker comes in handy because it keeps the fish from being dragged away by the tide or pounded by the force of the waves.  This is a key adaptation when it comes to protection.  I have added a link under the "Helpful Links" column.  The field guide "Life Between The Tides", is also available for checkout from the Marymount Library.

WELCOME TO ASK THE MARINE BIOLOGIST!

Welcome to the one-of-a-kind resource for ALL THINGS MARINE BIOLOGY!  I provide a question and answer service for anything and everything you could possibly wonder about the treasures our oceans have to offer.  This is meant primarily for Marine Biology Students at Marymount College in Rancho Palos Verdes, Ca. and at Auburn University in Auburn, Al.  but ALL ARE WELCOME!  My goal is to spread my love and appreciation for our oceans and their inhabitants to everyone while acting as a resource where you can get your personal questions answered.  Please enjoy and share my page with as many people as you can.  I hope that I can be as helpful to my fellow colleagues as possible.

Thank You Again For Visiting.
