SSF Builds 26 Affordable Tuna Longliners With Excellent Freezing Systems for Seychelles

Seychelles is an archipelagic island country in the Indian Ocean at the eastern edge of the Somali Sea and has obtained permission from IOTC to purchase 30 tuna longliners (fifteen vessels per procurement). In 2014, the buyer from Cecilia Island visited SSF and decided to get SSF to build 26 of them!

Because of the Covid pandemic, the handover process was a holdback, but eventually, the issue was overcome. In 2021, FV TUNA PEAK NO.16 will be the last vessel to be delivered. All 26 longliners will be completed this year. All tuna fishing boats are expected to be economically beneficial to the island based on the design of the boats, which are cost effective, eco-friendly, and long-lasting.

Economical and Efficient 300 Ton Ultra-Low Temperature (-60 Degrees) Fishing Boat

As fish stocks decline, the international fishery organization's fishing quota has been adjusted to protect the oceans, including the Indian Ocean, Pacific Ocean and Atlantic Ocean, which are the major commercial fishing regions.

Due to catch limitations, large sized fishing boats are no longer profitable. In addition to that, large tuna fishing vessels between 500-700 tons have high labor and fuel costs, maintenance fees, and lost productivity due to maintenance. Given that, tuna fishers are eager to find alternatives. Many owners demand small-scale boat size to make sure their business remains competitive.

SHING SHENG FA BOAT BUILDING CO., LTD. (SSF) has developed 300-ton tuna longlining fishing boats using fibre-reinforced plastic (FRP) material for the hull and some parts with high-speed motors to maximize the performance of vessels. The primary design concept is to reduce the size and weight to save cost. Smaller boats, less fuel, and smaller crews are needed. More importantly, the fishing capacity and effort remain the same. Fishers get to generate profits in the industry. For example, a 400-ton FRP tuna longliner built by SSF has the capacity to handle 200 tons of catch. Ultra low temperature freezers in the boat can preserve species, including thunnus albacares, thunnus obesus, and xiphias gladius, which are more valuable

A typical 120-day outing using SSF built tuna longliner could save approximately USD 30,000 on fuel. Regardless of whether it's casting a longliner or catching fish, it is less time consuming because of the smaller space. Comparing to large steel vessels, the wide space of the deck takes longer to get ready for the next operation.

FRP Ultra-Low Temperature Longlining Fishing Advantages

Deep-sea fishing can be done in two ways: fishers sail back to harbor when the boat is loaded or when the boat is low in fuel. The other way is to relocate fishes to other boats that have ultra low temperature freezers in the ocean, reload the necessities, and continue the journey. It will take about 6 months before heading back. For the deep-sea fishing, most fished species comprise tuna, shark, and marlin. Such practices take place 200 nautical miles outside of the coastline between the Indian ocean, North Africa and Antarctica.

The refrigeration systems in the FRP freezes fast and can reach -60 degrees with consistency The chilling system in the FRP freezes fast and can reach -60 degrees with consistency.

One of the best properties of fiberglass is that it is not sensitive to variations in temperature. And deep-sea fishing needs ultra-low temperature freezers to store the catch quickly on board to prevent the spoilage. Since fiberglass has lower heat conductivity, the chilling system in the FRP freezes fast and can reach -60 degrees with consistency.

When having two identical motors installed in FRP and steel made vessels, FRP saves 10-15% fuels. Besides lower fuel cost, the charge for FRP's maintenance is low also. The cost for a steel boat that lasts 30 years is huge, it includes the cost for passivation process, annual maintenance, and a full check up every three years. Unlike FRP vessels, its lifespan is 50 years. Annually check up is not required if there's no damage. Overall, FRP is energy-efficient, has longer service life, and lower upkeep cost.

Between steel and FRP fishing boats, the maintenance cost for a 30-meter FRP fishing boat is only 1/10 that of steel. Overall, an FRP boat might be a bigger investment, 15%~25% higher than steel, but it is still worth the price.


Steel made boats are expected to last 30 years, FRP lasts 40-50 years.
 

Having the advantages of high strength, anticorrosion and easy molding, fiber reinforced plastics (FRP) have become a commonly used material for building boats, such as fishing boats, yachts, and speed boats. And the boats that are built by FRP have low thermal conductivity, lower fuel cost, are lightweight, and have a longer lifespan, while steel made boats are expected to last 30 years, FRP lasts 40-50 years.

Hook, Line & Tuna - Longline Gear and Operation
The mainline shooter of tuna longliner from SSF The length of whole mainline is 50 kilometers long with 13-16 bait hooks between floats.

Mainline shooter, reel machine, line hauler, and capstan is the equipment for tuna longlining. Setting the longline gear involves putting mainline, branch line and baithooks into water. Longline casting and reeling both can be done by machines to prevent tangle. Mainline is slowly cast while deciding the depth of bait hooks in the water. Baited hooks attached at intervals by means of branch lines before deploying into the water.

Mainline and floatline with floats to support the entire longline, branch line with baits, radio beacon and longline are the major longline fishing gears. The length of whole mainline is 50 kilometers long with 13-16 bait hooks between floats. A large number of baited hooks can hang from a single line.

Reeling tuna onboard can be done using a reel machine. Hooked fish is removed from the branch line and the line is organized by a winder.

Ultra-Low Temperature Longlining Fishing For Sashimi-Grade Tuna

Sashimi-grade tuna requires a series of fish handling processes to ensure the quality of flesh. The better quality of flesh, the higher the price. Thus, -60 degrees ultra low temperature environment is required along with all the processes from catching, gutting, the fish, shipment and logistics.

After the blood is drained and the gutting is done, because the bacteria accelerate the process of deterioration, they should therefore be removed to a freezer as quickly as possible for better-quality meat.

Freezing over a hundred kilograms of tuna in less than 10 hours is crucial. The process includes the inner body of the tuna reaching -60 degrees. When the meat is completely frozen, the fluid in the fish would stop moving therefore reducing a change in color or contamination of the tuna.

FRP longliner's freezer from SSF is not only able provide -45 degrees chill rate, -60 degrees onboard catch storage in 48 hours can be achieved to make sure all tunas is served in the best condition.

Species That Are Suitable For Longline Fishery
Longlines are used to target a variety of tuna species including: Thunnus albacares, Thunnus thynnus, Thunnus maccoyii, Thunnus alalunga, Katsuwonus pelamis, Thunnus obesus, Xiphias gladius, Tetrapterus audax, Istiophorus platypterus, Istiophorus albicans, Makaira Mazara (Makaira nigricans), and Makaira indica.
