Biomass of the lobsters/octopus/Kina
Can weigh up to 5kgs
In 2040 the biomass of the octopus will increase because the humans won't fish out the lobsters, and even though the octopus will still prey on the lobsters it won't have a effect on the population of the lobsters because they will keep reproducing.
