EFFECT OF TEMPERATURE ON GROWTH OF 
YOUNG BLENNIES (ZOARCES VIVIPARUS). 

By E. M. MEEK. 
Amongst some experiments which are being made on young 
fish (as to the effects of various conditions on growth) the influence 
of temperature on young blennies is being observed. In the case 
of this experiment two tanks were used: one was allowed to 
remain at the normal temperature and the other consistently 
maintained at a higher temperature. In each of these, blennies, 
from the same mother, born in the Laboratory, were placed and 
measured every week for the first two months of their life, and 
subsequently every fortnight. Unfortunately some of the blennies 
died, but it will be seen (in Figure 5), as was expected, that the 
higher temperature leads to more rapid growth.
