Alligator gar season in Texas: How to safely catch and release - Houston Chronicle

While fishers may be anxious to catch and release their first alligator gar, the Texas Parks and Wildlife Department and other agencies want the fish to be protected due to their status as "threatened" according to the American Fisheries Society.

Here's what to know about alligator gar and how to keep them safe while enjoying the fishing season.

What is an alligator gar?

An alligator gar is a freshwater fish located along the Mississippi Gulf Coast and near the coast of Galveston. It is the largest species of gar and one of the largest freshwater fish, with ancestors found in fossils 215 million years old. The fish are known for keeping the aquatic ecosystem balanced and healthy, feeding on buffalo fishes, carp and shad. 

"Catch-and-release fishing for alligator gar has become quite popular and data from a current evaluation in progress indicates high survival rates for released fish," Dan Daugherty, TPWD Inland Fisheries senior scientist, said. "We've even recorded some fish being caught and released three or four times over multiple years."

Alligator gar can live up to 50 years. TPWD said their lifespans can be extended through safer catch and release methods and practices. They are also non-threatening to humans.

Are alligator gar an endangered species?

No, but they are considered threatened by the American Fisheries Society.

Dan Bennett, expert with the Inland Fisheries Denison District for Texas Parks and Wildlife, said flood control efforts in recent years have reduced spawning habitats for alligator gar within Texas. 

"Texas really remains kind of the last stronghold of alligator gar populations," Bennett said. "What we're kind of trying to do is just hold on to that and preserve the fish because they really are a long lived species and may only have a successful spawning event every six to 10 years depending on the potential for drought conditions."

How can I catch and release an alligator gar safely?

Bennet said catching alligator gar can be difficult.

Using non-stainless steel single hooks, no larger than 3/0, is recommended for those who are fishing for alligator gar. Stainless steel hooks and larger hooks can damage their organs and take longer to degrade than bronze hooks.

The most common way to catch an alligator gar is to use common carp on a 3/0 treble hook or a J-hook. Fishers are advised by the TPWD to not use hooks larger than 3/0 as the fish are more likely to be killed when hooked deeply. 

If a hook is lodged too deep into an alligator gar's mouth after being caught, such as their throat, stomach or gullet, the TPWD recommends cutting the fishing line instead of removing the hook to avoid further harming the fish.

Larger alligator gar should be landed on shore instead of in a boat to avoid harming them while lifting the fish onto a boat deck with lassos or snares. When taking photos, fishers should support the heavy fish's weight and release quickly in order to minimize handling time.

Why is catch and release still safe for the species?

The TPWD considers anglers a part of the conservation efforts as long as they practice fishing safely. The population of alligator gar is allowed to thrive if fish are returned to their original catching spot. 

"It can be very difficult to successfully catch one," Bennet said. "Reading up on the methods used is important."

This fish is worth $300,000 - New York Post This fish is worth $300,000 - New York Post Posted: 05 Jun 2016 12:00 AM PDT With exacting precision, the surgeon inserted the scalpel above the eyeball and cut out a snotty deposit of fatty tissue. The routine eye-lift was nearly complete when suddenly the patient awoke, suffocating, and began to flop about on the table. The audience gasped. Knowing time was of the essence, the surgeon scooped up the patient in his arms, raced across the stage, and dropped her into a tank of water. She revived. Because she was a fish. Yes, fish eye-lifts exist. As do fin jobs and tail tucks. The operating theater was a mall in Jakarta, Indonesia, where a pet expo was under way. As for the patient, she survived, her formerly droopy eyes now bright and perky. A good thing, too, as this was no ordinary goldfish but rather an Asian arowana, the world's most expensive aquarium denizen, rumored to sell for as mu...

Catching Dory: selling aquarium fish supports coastal livelihoods in Indonesia | npj Ocean Sustainability - Nature.com

Abstract The global marine aquarium trade has created new local markets across the planet, including in Indonesia, now the second-largest exporting country of marine aquarium fish in the world. Participating in the global aquarium trade has been touted as a potentially sustainable addition to fisher livelihoods, but scant data exist showing the numbers of fish coming off the reef and how those fish contribute to income. To determine how participants in the trade incorporate aquarium species in their livelihoods, we examine source-level aquarium fish collecting and trading data in the Banggai Archipelago, a region in Central Sulawesi that has become a significant source for popular aquarium, also known as ornamental, fish species. Using a sustainable livelihoods lens, we examine this data to understand how participants in the aquarium trade both contribute to as well as benefit from the trade and consider how their participation relates to emerging Blue Justice principles. From one year...
