1. Lobster mating

Lobsters mating.

Lobsters mate in a sheltered location in the summer when the female has just moulted and her shell is still soft. Once they have mated, the male protects the female for a few days, until her shell hardens. Lobsters lay thousands of eggs but, in the first few weeks after hatching, very few survive.

2. Lobster fishing

Lobster traps. Homarus Eco-Centre rears the lobster larvae and releases them when they are stronger. First step: go lobster fishing and catch females carrying eggs. We use a baited lobster trap. Careful! You need a researcher to try to catch females carrying eggs because they are protected.

3. Choosing lobsters

Once the trap has been brought on board ship, the lobsters need to be sorted. Only lobsters of a certain size can be kept. The lobsters that are too small are released back into the sea.

4. Female lobster carrying eggs

Female lobsters carry their eggs on their lower abdomen for 9 to 12 months. Once they’ve been caught, the females are brought to the hatchery.

5. Hatchery

Hatchery's basins of the Homarus Ecocenter.

At the hatchery, the female lobsters are placed in basins containing seawater. The temperature, salinity and oxygen conditions are optimal for the eggs to continue developing. After a few weeks, the eggs hatch into larva, which are fed with small crustaceans called artemia.

6. Lobster larva

Lobster larva

Young lobsters go through four larval stages before they are strong enough to be released back into the sea. In stage IV, the larvae already resemble small lobsters.

7. Larvae release

Lobster larvae release.

In stage IV, the lobster larvae are cannibals and fight each other constantly. As a result, it is difficult to keep them in the hatchery any longer: they have to be released into the sea. First they have to be sorted. In the sea, the larvae are placed gently on the sea floor using a tube. From there on, the small lobsters will hide and continue growing.
