Table 14 presents the dominant species data for borrow sites Bl and 

 B2 for both the November -December and May samplings. Both stations 

 exhibited relatively high levels of oligomixity in November-December with, 

 more than 80 percent of fauna represented by only four species (site Bl) 

 and three species (site B2) . The faunal distribution improved significantly 

 by May with the number of species representing more than 80 percent of the 

 fauna doubling for each site. 



Faunal composition between corresponding stations of the nine transects 

 did not vary substantially for either sampling period. Examination of the 

 composite lists and faunal counts (App. B, Tables B-1 and B-2) shows that 

 species numbers varied little between stations. Faunal counts showed some 

 variation between corresponding stations. However, the largest variations 

 were usually due to a greater or lesser abundance of a dominant species. 

 The overall pattern of faunal composition is dominance by several species 

 over all corresponding stations with "rare" species distributed rather 

 uniformly over all stations. 



(2) Species Richness . The number of species found at each station 

 is presented in Tables 16 and 17 for November-December and May, respectively. 

 Species richness ranged from 6 to 39 species (stations 7-1 and CB) for 

 November-December and 4 to 43 species (stations 9-1 and CB) for May. 

 Generally, the number of species increased with increasing distance from 

 shore for both sampling periods. Control stations CA and CB exhibited 

 the greatest number of species for both sampling periods. The borrow sites 

 generally had species numbers comparable to stations 2 or 3 of the transects. 

 Overall, there was relatively little variation in species numbers between 

 comparable stations of the nine transects (see Tables 16 and 17) . 



(3) Faunal Density . For the November-December sampling period faunal 

 density ranged from 192 organisms per square meter at station 1 on transect 

 4 to 4,912 organisms per square meter at station 4 on transect 8. For May 

 the density ranged from 336 organisms per square meter at station 1 on 

 transect 8 to 6,064 organisms per square meter at station 1 on transect 1. 

 Faunal density estimates for all stations are listed in Tables 18 and 19, 

 Faunal densities for stations 1, 2, 3, CA and CB were generally greatest in 

 May with the exceptions of stations 2-1, 8-1, 9-1, 1-2, 6-3 and 7-3, which 

 exhibited the greatest densities in November -Dec ember. Stations 4, 5 and 

 the borrow sites Bl, B2 had the highest faunal densities in November- 

 December with the exceptions of stations 2-4, 3-4, 9-4, 2-5, 3-5, and 4-5 

 having greater numbers in May. Overall, the nearshore stations and CA and 

 CB exhibited greater faunal densities in May than November-December with 

 the offshore stations and borrow sites having greatest densities in 

 November-December. Variation among corresponding stations over the nine 

 transects was largest when the faunal densities were greatest (e.g., varia- 

 tions in faunal density for stations 1, 2 and 3 were largest in May, 

 corresponding to greatest faunal densities) .
