 J/iTo Appell/f has, ppo .1-S8-142, made very detailed calculations 

 in order to shovir that a rearing to the 4th stage, is'much more 

 profitable than a mass hatching and putting out-of.tho nowly hatched 

 broodo He _calculates: ■ ,

These are Appelljz^f 's. cp.leuiationss Kis calculations are, 

 however, vn^ong* . ' 



ViOien a bag of 5 x 5 x 3 feet has a capacity of one million 

 spawn, another bag of 10 x 10 x 3 ffe'et will have a capacity of 

 four million (not tiivo million as given by Appell/f )« The five 

 hfitcheries v/ill therefore give 400 million spat/n and hatch 360 

 million brood, v/hich again will represent .360,000 lobsters which 

 can be used for food_, ii,eo T/h3,ch are eight, inches longo ' "'

The' five h atcheries mentioned above, will, for the same amount, 

 9),000 L-rdner' deliver 75 0^000 brood in the .4th stage, i.e. about 

 ■1 inch longo 



I csannot agree as to Professor. Appell/f 's theory that 750r000 

 young in the 4th stage are much more valuable than' 360 million 

 brood in the first stage, when these represent 360,000 grovr.^.-up 

 lobsters. It takes seven. yeafs for the 750,000 to reach such a
