How to recognise it

The Gulf Menhaden (Brevoortia patronus) is a slender, elongated fish. It has a silver body with a bluish-green back. The sides are marked with a series of small, dark spots. The dorsal fin is located far back, and the mouth is large, extending past the eye. This species is often confused with the Atlantic Menhaden (Brevoortia tyrannus). The key difference is that Gulf Menhaden have a more pronounced fork in their tail fin.

Where it lives

The Gulf Menhaden is primarily found in the Gulf of Mexico. Its range extends from Texas to Florida. They inhabit coastal waters, estuaries, and bays. Typically, they prefer shallow waters, usually between 10 to 30 feet deep. During warmer months, they move closer to shore. In cooler months, they may migrate to deeper waters. They often seek cover near vegetation and structures like piers and jetties.

When it bites

The best months for catching Gulf Menhaden are from April to October. They tend to bite when water temperatures are between 70 to 85 degrees F. Early morning and late afternoon are the most productive times. A passing front can trigger feeding activity, while strong winds may scatter schools. A full moon can also enhance their feeding behavior, making them more active.

How to catch it

To catch Gulf Menhaden, use a small cast net or a light tackle rig. A 1/0 to 2/0 hook works well with a 10 to 15-pound test line. Popular baits include small pieces of shrimp or cut bait. When using lures, opt for small jigs or spoons in silver or chartreuse colors. Cast near schools of fish, especially around structures or moving water. Retrieve slowly to mimic natural prey.

Size, age and the table

Gulf Menhaden typically reach lengths of 10 to 12 inches. A trophy fish is considered to be over 15 inches. They grow quickly, reaching maturity in about 2 to 3 years. Their lifespan can extend up to 5 years. While they are not commonly targeted for eating, they are used as bait in many fishing scenarios. Handle them carefully to ensure a successful release back into the water.

Biting calendar

Continental-US average by month; your water may shift it a few weeks.

Gulf Menhaden are primarily filter feeders and are most active when water temperatures are warm. Their biting is driven by the availability of plankton, which is their main food source.

How to fish

Use a light tackle setup with small hooks and a variety of baits such as small jigs or sabiki rigs to catch Gulf Menhaden. They are often found in schools, so casting near the surface where they are feeding can yield good results. Look for them in shallow coastal waters and near estuaries.

Biology

Gulf Menhaden spawn in the spring and summer months in estuarine and coastal waters. They primarily feed on phytoplankton and zooplankton, playing a crucial role in the marine food web. Their habitat includes estuaries, bays, and coastal waters.
