occurred there. The OSI was lower and the apparent RPD was smaller there. The depth of 

 the apparent RPD was most shallow at SP and OA, indicative of sediment organic 

 enrichment and deepest at YB. However, contrary to expectation, the TOC and total organic 

 nitrogen (TON) concentrations were the lowest, or among the lowest, at YB. Both TOC and 

 TON were highest at OA. The density of Clostridium perfringens spores was over an order of 

 magnitude higher at OA than elsewhere. 



Biological Characteristics of Fish Samples: Results 



All of the individual data from the fish that were evaluated are listed in Appendix C. 

 They include data on the gender, size, weight, and measures of biological effects. 



Fish were located and captured at the BK, OK, VJ, SP, and RR sites in November- 

 December; and at the BK, OK, VJ, and SC sites in January-February. About 15 fish were 

 caught and used for evaluation at each of the five sampling sites in the first sampling 



(November-December). 



Females predominated at all sites, except SP where a nearly equal number of males was 

 obtained in November-December (Table 23). Mature fish were most commonly examined at 

 three of the sites; however, roughly equivalent numbers of immatures were found at the VJ 

 and SP sites. The lengths of the fish were similar at all sites, although SP fish were 

 slightly smaller and those at the RR were slightly larger than those at the other three 

 sites. The relatively high proportion of immature fish at SP was reflected in the small 

 mean length of the fish. The liver/body weight ratios and condition factors were similar 

 among all sites and there was relatively low variability in the data from within the sites. 

 The gonad/body weight ratios, however, showed greater differences among the sites, and 

 were highly variable within sites. Relative to the other sites, the gonads in SP fish, 

 where the most immatures were captured, were smaller. The RR fish which were the 

 largest also had the highest gonad/body weight ratios.
