Identifying Fish

Hi Guys

I see in the members gallery that there is some confusion about the different shark species.  I am willing to help. As I've been the records officer for my angling club for the past three years I had to learn to identify fish for our record purposes.

Any one who is battling to identify please posty a pic of the fish and i will try my level best to identify it.

Small young sharks are hard to identify as the juveniles all look quite similar, most with black tipped fins/tails etc. When somebody says they caught a small Grey, I think Dusky, whereas the name seems to be used for any grey shark whether its a dusky,blacktip,milkshark,spinner and the rest. Any help here to easily identify them would be a help!

Thx

Howzit Dup.

I fish for REQUIN in Central Gauteng and one of the problems we have is the weight to lenght ratios. I personal use the western province shore angling ass (WPSAA) conversion tables and this differs considerably to other conversion tables for the same species.

How can this be rectified.

Hi There Guy's

I also have found that diferent provinces tables differ slightly.

I have used ORI website calculater is this the most accurate source of reference for us to use.Your advise and comments will be helpfull for me on where and what sources to use..

Cheers Riymos

Even ORI can't answer this, I've tried.

Fishbase have several algorythms for each species. I suppose its because the growth rates and condition of species can vastly differ from habitat to habitat.

(I'm a Homo Sapiens species, I am 6ft tall.....how much do I weigh!)

Maybe we should forget weights and just go with length! I just wish there was one length to worry about...

Standard, fork, total, precaudal, disk width.....

I don't have a problem with the different lengths. There should be one standard table throughout all the provinces.

The point is, a 1metre yellowtail caught off Cape Point will likely not weigh the same as one caught off Durban!
