If you own or operate an industrial or commercial fishing vessel, it’s important for you to have the proper cooling system to meet your needs. Improper cooling of seafood leads to the growth of dangerous bacteria that makes it dangerous to consume. The type of cooling system you need for your vessel depends on several factors. Read on to find out what we at Semco recommend.

The Size of the Fish You Catch

The cooling system you need will depend on whether you catch small, medium or large fish. Naturally there are a host of other factors and species of fish, your own resources, the weather, and other conditions will also impact the best cooling method. However, in general consider the following:

Small Fish – Small fish such as sardines spoil easily since their size means they aren’t as protected. However, they also cool quickly and stay cool longer because they are so small. A well-insulated cooler for small fish is important. To keep them cold enough, use a mix of ice and chilled seawater in the cooler.

Medium Fish – Medium fish such as salmon or tilapia are some of the most important economically, so it is vital they stay fresh. When it comes to medium fish, other factors such as the distance of your trip will factor into the best type of cooling.

Large Fish – Large fish include marlin and Mahi Mahi and take much longer to cool. Large fish should be gutted before cooling so you can place flake ice directly into them to maximize cooling efficiency.

The Type of Seafood You Catch

Fish sizes are important, but the type of seafood you’re bringing in from sea is also important. Shrimp are a special case because they begin to spoil as soon as they die. For this reason, shrimp need to be frozen right away. Common methods include plate freezing and cold brine immersion. Other types of shellfish such as lobster and crab are typically kept alive while in transport to prevent spoilage and ensure maximum freshness.

Available Space on the Boat

Available space is also a factor in determining what type of cooling system to purchase. For example, a system that uses polyurethane foam for insulation could be beneficial if it is placed in an area that is sure not to receive any water, but it might not be beneficial on small boats. Water spray will eventually weigh it down. Waterlogged polyurethane loses some of its insulating properties. Other types of insulation include sealed air space and even Styrofoam. The industrial cooling systems here at Semco are able to work with any type of insulation and space you have in your boat.

The Cost of the System

Cost will be a factor when it comes to the cooling system you purchase for your commercial fishing boat, but we at Semco work to ensure we have products available in a range of prices. However, it is important not to cut corners when it comes to cooling and insulating the fish you bring in. Purchasing a system that’s inadequate for your needs in favor of saving money will cost you in the long run, if not in lost product, then in lost business if someone becomes sick due to inefficient fish cooling.

Semco offers an array of options when it comes to your fishing needs, from ready-made ice that works for short trips to icemakers and water filtration systems for longer fishing excursions. All it takes is the right system to ensure delicious, fresh fish when you hit the shore. Make sure to check out our other seafood cooling articles for additional information.
