Fisheries Management

Studying Fish Populations

Responsible fisheries management starts with sound scientific information on fish populations, the ecosystems they inhabit, and the fisheries that depend on them. Our biologists use a variety of methods to gather this information, including conducting scientific studies of fish and shellfish populations and the environment to collect fishery-independent data and examining fishermen’s harvests to obtain fishery-dependent data. They then use these data to assess the status of fishery resources. They share this information not only with Louisiana’s management authorities but also with regional, national, and international interests. Managers use this information to make decisions about appropriate management measures to ensure the long-term health of resources and viability of fisheries.

Artificial Reefs

Artificial reefs are man-made structures intentionally placed on the sea floor. Artificial reefs can be created from materials such as cleaned vessels and recycled concrete. These materials are meant to increase the surfaces suitable for encrusting organisms, such as oysters or corals, to attach and grow. The added material also provides refuge to animals that may be vulnerable to predators. Artificial reefs enhance fishing for fishermen and scenery for recreational divers.

Freshwater Fish Hatcheries

Louisiana’s freshwater fish hatcheries are an integral part of LDWF’s mission to enhance fish populations and provide more opportunities for the public to use and enjoy these resources. Having the ability to produce and stock areas with healthy sportfish from our hatcheries is a valuable tool that helps reach management goals, such as meeting public demand for catching a trophy bass in Louisiana waterbodies.
