April 1st marks the start of the annual closed season for the Bahamian spiny lobster (otherwise known as crawfish) fishery, which will continue until July 31. 

This seasonal closure is a crucial measure aimed at ensuring the sustainability of one of the country’s most valuable marine resources. With Bahamian lobster exports generating close to $100 million annually and supporting thousands of livelihoods, maintaining a healthy lobster population is essential for both economic stability and marine conservation.

In Central America, over 50,000 people are directly employed in jobs related to the spiny lobster fishery, an industry which generates upwards of $450 million annually. In this region, The Bahamas is the largest exporter of spiny lobster.

Note: Last month, the Cape Eleuthera Institute mistakenly published an article in The Eleutheran with a typo. Closed season for spiny lobster in The Bahamas is April 1-July 31.

The Importance of Lobster Fisheries to The Bahamas

The spiny lobster fishery is one of the most economically significant fisheries in The Bahamas. Making up 80% of the country’s total fisheries income, it makes a significant contribution to the country’s gross domestic product (GDP) and employment, particularly in fishing communities. Lobster tails are a major export product, with the majority shipped to the United States and Europe. 

Beyond its economic value, the spiny lobster fishery is deeply rooted in Bahamian culture and tradition, sustaining generations of fishers and playing a vital role in coastal livelihoods. Given its importance, maintaining a balance between harvesting and conservation is imperative for many reasons, especially for economic and cultural purposes.

Safeguarding Future Populations

Given the importance of this species to the Bahamian fishing industry and the wider public interest, Bahamians have implemented various conservation efforts to ease some of the fishing stress on natural populations of spiny lobster. 

Some of these conservation efforts include:

-Catch quantity limits—a maximum of 10 lobsters in a vessel during the open season

-Catch size limits—tail length must be a minimum of 5.5 inches

-Closed season that prohibits spiny lobster collection from April 1st through July 31st when the lobster populations are at their most vulnerable during their reproductive season

-Gear restrictions aimed at encouraging less exploitative fishing practices while continuing to allow Bahamians to benefit from fishing. Scuba gear or air compressors are not permitted, and Hawaiian slings are the only approved spearfishing device allowed in The Bahamas.

-Restricted fishing areas—spearfishing is not allowed within one mile of the coast of New Providence or Grand Bahama. Persons must not spearfish within 200 yards off the coast of all Out-Islands.

These efforts are necessary to protect the spiny lobster, as only about 3% to 5% of young survive past their larval stage to become adults. To ensure future success of spiny lobster populations, fisheries regulations must be enforced.

The Potential for Aquaculture in Lobster FisherIES

Aquaculture is emerging as a promising solution to supplement wild spiny lobster fisheries and reduce pressure on natural populations. Several countries have explored or implemented lobster farming initiatives to enhance production. While full-scale spiny lobster aquaculture remains challenging due to the species’ complex life cycle, research and development efforts continue to refine techniques.

At the Cape Eleuthera Institute (CEI), researchers are actively exploring aquaculture as a means of supporting the local spiny lobster industry. The work focuses on developing sustainable grow-out systems and refining feed formulations tailored to lobster nutritional requirements. By studying the feasibility of controlled lobster farming, CEI aims to provide alternative solutions for sustaining lobster populations while maintaining economic viability for local fishers.

Reimagining Lobster Nutrition 

While typical formulated aquaculture feeds rely heavily on fishmeal and other fish products for protein, fat, and flavour, these feeds come at a cost to the heavily exploited wild fish populations. 

Furthermore, many of these fish populations are also facing increased pressure from human consumption, meaning the demand for fishmeal from these sources also impacts local fisher people. Global fishmeal production has historically hovered at 5 million tonnes annually, but this is estimated to grow by about 9% by 2032.

Despite historic reliance on fishmeal and fish oil, a number of promising alternative nutrient sources exist; many of which are considered to be significantly more sustainable than wild caught fish. Several have even started making their way into trials for commercial aquaculture feeds. These include algae biomass, rice bran, wheat, yeasts, and insect meal, just to name a few.

Could Insects be the Solution?

Insect meal has been of particular interest to the global agriculture community in recent years, as insects have shown very promising results in converting organic matter into useful protein and fat. Additionally, they require much less space to grow, reproduce rapidly, and can be sustained with food sources that would otherwise not be suitable for other animals. The aquaculture industry has recognized this potential and is forecast to use approximately 40% of all insect protein produced by 2030 (500,000 tonnes).

Innovative Spiny Lobster Research at CEI

Researchers at CEI are currently investigating alternative food systems for raising spiny lobsters in a controlled setting. These food systems are focused on applying more sustainable nutrient sources such as insect meal as replacements for fish meal and fish oil.  

A feed trial is currently underway to highlight the feasibility of black soldier fly larvae as a protein source in feed formulations for spiny lobsters. Prior research has shown that black soldier fly larvae meal is an effective source of both protein and fat for finfish such as tilapia and trout, but few have looked at its effect on Bahamian spiny lobsters. 

In the first-of-its-kind feed trial for this region, researchers will compare the performance of three diets: a native snail-based diet, a diet similar to commercially available feed (a mixture of krill meal and green lipped mussel meat), and a diet containing of black soldier fly larvae meal.

Not only will this research help to alleviate stressors on wild fish populations, but it will also provide a more consistent and reliable source of feed for spiny lobster aquaculture.

Beyond the Lab

The research team at CEI is also exploring the use of plastic cages which can be placed in nearshore areas to house the lobsters while allowing them to feed on their natural diets. 

These cages provide a semi-controlled environment where juvenile lobsters can grow until they reach marketable size, reducing reliance on wild stocks. The panels in the cage are adjustable, allowing for juvenile lobsters of all sizes to be comfortably housed as they feed and grow. This method has shown promise in pilot studies, offering a potential bridge between wild fisheries and aquaculture.

A Sustainable Future for The Bahamas’ Lobster Industry 

The Bahamas’ spiny lobster industry stands at a crossroads, where conservation and innovation must go hand-in-hand. 

By enforcing strong fisheries management practices and investing in aquaculture research, the nation can secure a future where lobster populations thrive, fishers maintain their livelihoods, and Bahamian seafood remains a global delicacy. Whether through sustainable feed innovations or pioneering grow-out systems, efforts like those at CEI demonstrate that the future of lobster fishing can be both profitable and environmentally responsible. Through continued commitment to research, policy, and community engagement, The Bahamas is poised to lead the way in sustainable spiny lobster production for generations to come.
