Anong n lot of fishermen there is the opinion tht\t tlie lobster 

 is a "ini-rratinp; fish" virhich coirics in froin the ocean in large schools. 

 In any other T/ay they can not explain how they can continue fishing 

 lobster in the same grounds, every single year: - they fish each 

 year as Ion;; as they think there is a single lobster to be taken© 



The thing is (in the meantime) however, that just a few of the 

 lobsters creep into the nets, especially those ivhich have just shed 

 their shells, and lobsters v/ith old shells creep into the nets 

 especially when the temperature rises strongly in the spring,— 

 that's when they are hungrye ^.s long as the vrater is cold the 

 lobster needs a minimum cf food* 







This conduct: — thr't all lobsters do not as willingly creep int 

 the nets results in a condition that there is always stock left 

 behind, even if men fish ever so intensely. If this were not the 

 case, the lobster fishery wouldn't hove held out as well as it has* 



To study these questions, they vrorked at lobster fishing every 

 month the v;holc year tlirough, in one big salt water basin v;here 

 beforehand vre had slipped in a lot of full grovm lobsters* In spite 

 of knowing there v/ore lobsters there,— we didn't catch a single one 

 the vmole winter throughe As soon as the v/ater became vrarm, vre got a lot 

 right a.fter they had shed their shells,— all through the suiranero Simul- 

 taneous experiments in nat\ire (under natural conditions) shovred the 

 same results*
