Excerpt: . . . Larva Sal inity. As eurytopic organis: ns, American oyster larvae are able to withstand a wide range of ambient sal inities. Their sal inity tolerance depends on the salinity at which the parents were held during gametogenesis ( Davis 1958 ). The salinity range for the development of nomal, straight-hinge ( 0-stage ) veliger larvae from eggs of low salinity. oysters ( 8. 7 pp was 7. 5 to t ) t, 22. 5 pp whereas the range for eggs from oysters conditioned at 26. 0 to 27. 0 ppt was from 12. 5 to above 35. 0 ppt ( Davis 1958 ). Larval growth is affected by reduced salinities; growth at 7. 5 to 10. 0 ppt is appreciably slower than that of sibling larvae reared at salinities of about 15. 5 ppt ( Calabrese and Davis 1970 ). Growth of oyster larvae is not inhibited, however, after a drop from 27. 0 to 15. 0 ppt ( Davis 1958 ). r1etamorphosing oyster larvae will set ( attach ) at salinities between about 5 and 35 ppt with optimal setting occurring between 10 and 30 ppt and maximal setting at 18 to 22 ppt ( Carriker 1951; Davis 1958; Calabrese and Davis 1970; Dugas Chatry and Dugas analyzed 11 years ( 1971-1981 ) of ns. ), Chatry and spatset data from Louisiana and found that 35 of the spatset occurred between June and September when mean sal inities ranged from 16 to 24 ppt, Setting cm ) ( intensities were consistentll high 3 s pat between 16 and 24 ppt with a peak of more than 12 spat cm between 20 and 22 ppt.
