Rescue and release of Lobsters 2016

Lobsters and reef crabs are an important part of the coral reef ecosystem.  Unfortunately large crustaceans taste good to people and the reef population is much smaller than it should be.  To help balance the eco system it is important that we have as much biodiversity as possible.  The role of lobsters in the ecology of a damaged reef is not well known but as major predators they clearly affect a wide range of prey, from starfish and clams to other crustaceans.

Moving rescued lobsters back to the reef


There were a few lobsters on the island (surveys to 2016 counted 4 at 3 different places),  this lobster release should increase the breeding population with dispersal of larvae over long distances.
Unfortunately lobster biology is complex,  larval lobsters live in the plankton for many months and so the lobster parent reef can be many thousands of kilometres from the reef where the juveniles settle. 

TRACC negotiated with a commercial lobster farm and managed to buy 12 lobsters for wholesale price.
 
Long life on the reef rather than a quick boiling in a saucepan.







The lobsters were moved to Pom Pom and released close to the lobster reefs and the deep tyre reefs.

Turtle and Lobster artificial reefs

TRACC staff and volunteers have developed the technology to make some larger artificial reefs. These add to our arsenel of techniques to repair reefs damaged by blast fishing.   See a blasted reef here,

See our crate reefs, ribbon reef and bottle reefs here.   The new reefs make an immediate difference to the marine life and we hope the larger structures will attract larger fish species.

The turtle and lobster reefs are comparable to reefballs (a patented technology) but they are a lot simpler and cheaper to make by poor village commuities.

Lobster reefs

TRACC makes several types of CORFU reefs which are larger and stronger than the ribbon reef bottle reefs.  The Turtle reefs are mostly hollow and make suitable reefs for schools of fish.  The lobster reefs are very complex internally and have lots of tunnels and passageways,  These are ideal for lobsters, crabs and octopus,

Lobsters Release on the House Reef

Basil, Tom & Alana with the Lobsters
Releasing lobsters is a surprisingly slippery process. They squirm, wiggle, and slide from the grasp of the hand. But before the lobsters can be released onto TRACC’s House Reef, the lobsters must make it to Pom Pom Island – wrapped in newspaper, placed on ice, and snuggled into a cooler.

When the body temperature of a lobster drops the metabolism and heart rate slows, allowing lobsters to survive for 2-3 hours in a significantly cooled state and induces a kind of hibernation, which reduces the stress caused by transportation. When they arrive on Pom Pom we unload the cooler from the boat and wade into the shallows to unwrap the newspaper parcels of lobsters. They emerge from they cold in an unexpectedly alert state and flail in our grasp, legs and antennae gesticulating rapidly. As quickly as possible we place them in the wicker baskets to be taken deeper. Yet, the
Lark & Tom Prepped to Release 
especially fidgety ones escape from our grasp and Tom must mission to retrieve them from the shallows.

Next, we don our scuba gear and form buddy pairs to bring the basket’s full of lobsters to what we hope will be their new home, carefully we place the baskets on the ocean floor near our newly crafted and placed artificial reef of a “lobster house” and tires. Lobster baskets safely placed we wait and watch. The lobsters test their new environment, peeking over the edge and testing the water with their antennae before clambering out of their baskets to explore the crevices of the tires and lobster houses as their new home. 

Lobster Basket
Over the next few days the lobsters disperse across the reef, sometimes spotted by eager TRACC divers. And sometimes, to entice the lobsters to make a permanent home, Tom goes back down to lay little sausages down by the tires and houses.


TRACC hopes that by releasing the lobsters into our house reef, we not only add biodiversity and beauty to the reef, but also balance our ecosystem. In addition to hunting for urchins and clams, the lobsters scavenge and feast on detritus. Playing as essential role in cleaning the reef and keeping it disease free.
