Squid Catching In Belize: A Profitable Venture?

Belize is home to a variety of squid species, including the Caribbean reef squid, commonly found hovering over reefs and turtle grass beds, and the Belize Rainbow Squid, which is known for its ability to produce electric shocks. While squid are not commonly caught for food in Belize, they are sometimes sought after by fishermen as a source of income. The country's coastline and marine ecosystems provide a diverse habitat for these cephalopods, making them a fascinating subject for exploration and research.

The Caribbean reef squid is the most commonly sighted squid in Belize

The Caribbean reef squid (Sepioteuthis sepioidea) is the most commonly sighted squid species in Belize. It is commonly seen hovering over reefs and turtle grass beds. Reef squid are generally wary of humans and will retreat if they feel threatened or are approached too quickly. They are usually found in small schools of four to thirty in the shallows associated with reefs.

The reef squid is a small, torpedo-shaped squid with undulating fins that extend almost the entire length of its body. They are approximately 20 cm (8 inches) in length, with individuals ranging from 6 to 12 inches. They exhibit specific characteristics to help them in their environment, such as tentacles for movement and feeding, and colour pigments that reflect their behavioural conditions.

Reef squid are able to rapidly change colours, and they use this ability to communicate with one another. They can send different messages via colour patterns to other squid on their left and right. They also use colour changes, along with shape and texture alterations, for camouflage and to appear larger when facing a threat.

The habitat of the Caribbean reef squid changes according to the stage of life and size of the squid. New hatchlings tend to stay close to the shore in shallow waters, while young squid congregate in shallow turtle grass near islands to avoid bird predators. Adult reef squid venture into open water and can be found at depths of up to 150 metres. When mating, adults are found near coral reefs at depths of 1.5 to 8 metres.

The Caribbean reef squid is the only squid species that is commonly sighted by divers over inshore reefs in Florida, the Bahamas, the Caribbean, and Brazil. They are also found in Belize, where they are occasionally caught by fishermen.

The Belize rainbow squid can discharge enough bioelectricity to power homes

In a fascinating development, a team of scientists in Belize, led by Dr. Dino Vanidici, has successfully harvested electricity from the Belize rainbow squid. This invertebrate species, abundant in the waters off Belize and across the Caribbean, has long been known to discharge bioelectricity, but it is only recently that scientists have been able to harness this power for practical use.

The Belize rainbow squid, through its electric discharges, can produce enough energy to power homes. Dr. Vanidici and his team have published their findings in the Journal of Invertebrate Science, detailing how they were able to collect the squid's electrical discharge onto a conductor placed in a pen. This was then used to charge a capacitor connected to a set of batteries. With around 200 squid per pen, the team generated an average of 20kW of power per hour, enough to run lighting and air-conditioning units at their research centre on Glover's Reef Caye on the Caribbean coast.

The team's success in harnessing the power of the Belize rainbow squid could be a breakthrough for sustainable energy in the region. Dr. Vanidici has emphasised that the process is harmless to the squid, which naturally discharge electricity for navigation, capturing prey, and even attracting mates. With an abundance of these squid in the waters around Belize, this method of energy generation could provide a new source of income for fishermen while also contributing to renewable power solutions.

However, critics have expressed concerns about the potential impact on the marine ecosystem. Sheila Granoche, of the Belize Aquatic Large Lagoon Society, cautioned that overharvesting of the Belize rainbow squid for power generation could disrupt the delicate balance of the seas. As the debate surrounding renewable energy sources continues, the successful utilisation of the Belize rainbow squid as a power source could have significant implications for small rural fishing communities in Belize and beyond.

The reef squid is a species of small, torpedo-shaped squid

The reef squid, also known as the Caribbean reef squid (Sepioteuthis sepioidea), is a species of small, torpedo-shaped squid. They are most commonly found in the Caribbean Sea in small schools of four to thirty in the shallows associated with reefs. Reef squid are part of the Cephalopod class of Molluscs, and exhibit specific characteristics to help them in their environment, such as tentacles for movement and feeding, and colour pigments that reflect their behavioural conditions.

Reef squid typically have undulating fins that extend nearly the entire length of their body, and they are approximately 20 cm (8 inches) in length. They are often encountered among shallow reefs and are usually unafraid of divers. In fact, they are curious about these intruders into their habitat. The mantles of newly hatched reef squid are about 8-9 mm in length, while adult male and female mantles reach 12-20 cm in length.

Reef squid closely resemble cuttlefish, with broad bodies that are less streamlined than those of other squid species. They can also move using jet propulsion, shooting water from their pallial cavity (an area inside their mantle) through their funnel to move rapidly through the water. The basic colouring of a Caribbean reef squid is a mottled medium green to brown on their dorsal (upper) side, with lighter colouring on their ventral (under) side. This provides camouflage from predators swimming above or below them.

Reef squid are social creatures, often found in small groups, and they communicate through a variety of complex signals. They can control the pigment in their skin to send messages such as readiness to mate, sexual identification, and alarm. For example, when signalling slight alarm, their brow ridges turn bright gold and their central arms turn white. When faced with an extremely aggressive predator, they can eject a cloud of black ink to hide and confuse their attacker.

The reef squid is commonly seen hovering over reefs and turtle grass beds

The Caribbean reef squid, commonly called the reef squid, is often sighted hovering over reefs and turtle grass beds. Reef squid are generally wary, and will retreat if they sense danger or are approached too quickly. They are small, torpedo-shaped squids, with undulating fins that extend across almost their entire body length. They are typically between 6 and 12 inches long, and are usually found in small schools of four to thirty in the shallows associated with reefs.

The reef squid's habitat changes depending on the stage of its life and its size. Newly hatched reef squid are 'semiplanktonic', spending most of their time near the surface or directly underneath floating vegetation. Young reef squid tend to congregate in shallow turtle grass beds near islands, staying just a few centimetres to a couple of metres from the surface to avoid bird predators. Older, more mature reef squid tend to avoid turtle grass, as it hinders their movement. Instead, they are found over a variety of sandy and coral bottoms, and have been known to travel between islands.

Adult reef squid venture out into open water and can be found at depths of up to 150 metres. When mating, adults are found near coral reefs in depths of 1.5 to 8 metres. Reef squid are the only species of squid commonly sighted by divers over inshore reefs in Florida, the Bahamas, the Caribbean, and Brazil. They are also found in Brazilian reef habitats due to a symbiotic relationship with juvenile fish, which they protect from open-ocean predators.

Reef squid are capable of rapid changes in skin colour and pattern through nervous control of chromatophores. They use these colour changes for camouflage, to appear larger when faced with a threat, and to communicate with one another during courtship rituals. They are able to send different messages via colour patterns to squid on their left and right.

The reef squid can be put into a trance by shining an underwater flashlight on them

The Caribbean reef squid (Sepioteuthis sepioidea), commonly called the reef squid, is a species of small, torpedo-shaped squid with undulating fins that extend nearly the entire length of its body. They are most commonly found in the Caribbean Sea, including the waters off the coast of Belize, in small schools. Reef squid are voracious eaters, consuming 30-60% of their body weight daily. They are also highly communicative, using colour, shape, and texture changes to convey information to other squid.

Reef squid are attracted to light, which is why commercial squid boats use giant lighting arrays. Underwater LED lights are also available for squid fishing, with blue and bright green lights being ideal as they are bright enough to penetrate the water.

The reef squid's attraction to light can be used to put them into a trance. By shining an underwater flashlight on them, they can be mesmerised and immobilised. This technique can be used by divers to get a closer look at these fascinating creatures or by fishermen looking to make an easy catch.

When using an underwater flashlight to trance a reef squid, it is important to consider the brightness and colour of the light. While reef squid are attracted to light, extremely bright lights may scare them away. Blue and green lights are recommended as they are bright enough to penetrate the water without being too harsh. Additionally, the duration of exposure to the light should be considered. Squid are known to be active hunters at night, so using the flashlight technique during the nighttime hours may yield better results.

Overall, the reef squid's unique response to underwater flashlights provides an interesting opportunity for both divers and fishermen to interact with these fascinating creatures.
