But the Clyde Nephrops fishery has also boomed in recent years in a situation which resembles that of the collapse of the Newfoundland cod fishery. Cod stocks plummeted due to overfishing and lobsters thrived due to reduced predation. Many scientists believe this is what is happening in the Clyde.
It has been reported from many sources this summer, that what was once thought to be an in-exhaustable supply of Prawns in the Clyde now seems to be struggling, with fishermen reporting poor catches of smaller Prawns
Latin name: Nephrops norvegicus
Normal size: up to 24cm long
Diet: Nephrops are scavengers and will usually come out of their burrows in the marine gloaming for a feed on worms and fish.
Habitat: found in the north-eastern Atlantic ocean and the North Sea, Nephrops build semi-permanent burrows in the sand about 8-10 inches deep. They grow at different rates depending on the sand content of mud on the seabed, but female Nephrops generally mature at 3 years of age after which they reproduce each year, mating in summer and spawning in September. The females will carry eggs under their tails until they hatch in April or May.
