As the trawler moves forward, the net captures shrimp and other marine life, which are then hauled aboard for sorting and processing. Trawlers are renowned for their versatility and are commonly employed in both inshore and offshore shrimping.
• Otter Trawlers: Otter trawlers are a variation of traditional trawlers, with the addition of “otter boards” on each side of the net. These boards act as wings, spreading the trawl apart while in the water, increasing the net’s horizontal mouth size and capturing a larger catch. Otter trawlers are favored for their efficiency in capturing shrimp over a wider area, making them ideal for open waters with abundant shrimp populations.
• Shrimp Dredgers: Shrimp dredgers, also known as beam trawlers, are designed for shallow-water shrimping, particularly in estuaries and bays. They use a beam, often made of steel or timber, that drags along the seabed. The beam is equipped with chains or mesh bags, which scoop up shrimp and other bottom-dwelling creatures as the dredger moves forward. This method is suitable for capturing shrimp species that dwell close to the seafloor.
• Shrimp Bycatch Boats: Shrimp bycatch boats focus on catching shrimp as part of incidental bycatch while targeting other fish species. They are equipped with gear like seines or trawl nets, intended for the primary fish species, but they end up catching shrimp unintentionally. Bycatch boats are essential for balancing ecological concerns while still making good use of the shrimp catch.

Each type of shrimp boat is crafted to excel in a specific fishing environment and capitalize on the nuances of different shrimp species’ behaviors. From the depths of the open ocean to the serene waters of coastal estuaries, these boats form a diverse fleet that brings the delectable bounty of shrimp from the sea to our plates.
