Larvae of one stage or another of nonexploited shrimp are present 

 the entire year at 15-, 25-, and 45-fathom stations, although in varying de- 

 grees of abundance. The occurrence of larvae at the 72-fathom stations ap- 

 pears seasonal, inasmuch as larvae were taken only between May and Novem- 

 ber. As was the case in Penaeus larvae, a direct correlation is evident be- 

 tween the seasonal occurrence of larvae and increasing bottonn temperatures. 



All larval stages, except the nauplial stage, were more abundant at 

 15-fathom stations. Nauplii were more abundant at Tj- a^nd 15-fathom stations. 

 Protozoeae at 15-fathom stations were the most abundant larval stages encoun- 

 tered. The larvae encountered at 45-fathom stations were deep-water shrimp, 

 i. e. , Solenocera and Parapenaeus.
