Thanks - nice post!
Could you direct me to some of these "many many posts" that mention growth rate ? I did ask a specific question; that one
New England is glorious - and very historical - as is Old England, I am sure!
i think your best bet is to decide which type of ray you want to research and go from there. the sticky says different types of rays grow to different sizes and therfore the growth rate will be different for rays that ultimately grow to a different size as im sure you are aware from other species of fish.
if you pick one type you will get more specific and more relevant reply's.
the sticky is a good place to start if your looking for a small ray too but hystrix, scobina and small marbles are a godo start for small rays and since they dont grow as large as others the growth
rate might look like its slower depending on your point of view. ie inches versus percentage. growth rate is probably the same but it will seem less because the adult size is smaller.
a larger adult size ray might grow 2 inches per xxxx
a smaller adult size ray might only grow 1 incc per xxxx
growth rate is acutally the same as they are growing towards the adult size at the same rate but most people would probably say the growth rate of the smaller adult is slower because it doesnt grow as large as the other.
there are several posts in the last few pages regarding breeing size, claspers and such but a search might bring up more info. but again if you can specify a particular type of ray people will be able to help more.
pic a type and let us know what you find out
