Earlier this week, marine experts raised alarm about Belize’s lobster stocks being overfished, warning that without urgent action, this valuable resource could soon be depleted. A former fisheries officer, however, had a different take, suggesting that climate effects and boat interference might be to blame for the lobster scarcity in some areas. He also pointed out that there isn’t enough research yet to definitively say overfishing is the cause. But the fishermen we spoke with, along with lobster expert Doctor Daniel Pauly, disagreed. Here’s Part Three of the Lobster Stocks story by Marion Ali.
Dr. Pauly debunks this theory and says there are indeed studies that have shown how and why lobsters disappear from certain areas, and it’s as simple as over-exploitation. That factor, Pauly says, has driven lobster stocks to the point of depletion in those areas.

“When a fishery begins, it is always the ones that are closer to the coast, closer to the cities, closer to the ports that are depleted first, that are fished first. Why? Because you have a low cost of transport with a boat and fuel costs and so on. So, it’s always like that, that in fisheries as the fishery develops, the fishers must go further off because the ones that were near are depleted, are gone. So, this is not because the animals move; this is because humans have removed the animals that were close, so you have to go further off. And anybody who tells you that the fish have moved, or the lobster have moved, this is the reason why they are not there anymore – anybody who says that doesn’t know anything about fisheries, because this is the strongest pattern that happens in fisheries.”
The Sea Around Us Initiative conducted its own independent research to bolster this position, and the results of the study were published in March of this year. In agreement with the data coming out of these research exercises (slides attached in Dr Pauly’s folder) are the findings of lobster expert, Dr Mark Butler. He shared information about how lobsters breed.

“Quite literally, the female produces an odor, a scent, that’s released into the water column. And that is what the males are then attracted to the females and come to find the females. But the mating process requires female acceptance.
They tend to mate sort of size-assorted. What that means is the smaller lobsters tend to mate with smaller lobsters. The bigger lobsters tend to mate with bigger lobsters. And one of the reasons for this, and a lot of our research has shown, is that, for example, if a small lobster mates with her, he cannot fertilize all her eggs because bigger lobsters produce more sperm to fertilize than do small lobsters. So big females have to have a big male to mate with.”
On the afternoon we accompanied the team, and it did not find any undersized lobster during their raids and searches. Belize’s revised fisheries law stipulates that for every undersized lobster tail found, there is a fine of a minimum of $50 per tail, along with a minimum of $1,000 for fishing for undersized commercial species.
