Table 15. Summary of 1985 24-hour lobster larvae entrainment studies. 



One larva collected alive. 

 One stage 11 



The numbers of larvae collected in night samples (27) was significantly higher than the numbers collected 

 in day samples (*)) confinning our 1984 observations. The two 24 h collections were conducted 1 wk 

 apart to examine the effect of tide on lobster larvae entrainment under different day-night conditions. 

 Results indicated that lobster larvae entrainment was not significantly influenced by tidal stage. 



Lobster larvae entrainment estimates from our IP program 1977-85 and from the 1984-85 lobster 

 larvae studies are presented in Table 16. The estimates were calculated by summing the volumes of all 

 samples collected over the study period, dividing that volume into the total cooling water volume over 

 the same period and multiplying that proportion by the number of larvae collected over the hatching
