Figure 5 



Comparison of total length (TL) and body weight (WT) growth rates of smooth dogfish by sampling year 

 and sex. Linear regression parameter estimates and statistics are given in Table 2. 



Table 2 



Growth rates of young-of-the-year smooth dogfish collected from the Little Egg Harbor-Great Bay estuary of southern New 

 Jersey between 1988 and 1990, estimated by linear regression of total length and body weights on dates of capture. All parameter 

 statistics are significant at P<0.0001. 



' Growth rates are highly significantly different among years ( ANCOVA, /*<(). 0001 ) for length and weight. 



2 Samples sizes are lower because sex was not determined for some individuals during 1988. Growth rates are not significantly different between 

 sexes.
