Did you forget the anus injection? We wont let you go lazy.
Yup.........good point. For heavy body fish you gotta inject 40% formalin through the anal opening. If you feel that was not enough you can make a small slit between pelvic fins and the anal fin. For Large fish like Masheer or Labeos measuring more than two feet you will need to make a deep slit on the right side of the fish before you soak the fish.
After its dead pin down the fish on a thermocol sheet with fins spread and take clear photographs of the below:
-Dorsal view, lateral view & anterior view
-Clear pictures of snout & mouth parts showing barbels (if any).
-Fin count; Dorsal, Pectoral, Pelvic, Anal and Caudal.
Please avoid pinning the fins open as it badly damages the membrane between the rays and makes fin measurements wrong. Use formalin to dab the open fin and keep it open.
Photographs can be used for reference but never use them to confirm the id of a fish. You are more prone to make mistakes with the morphometrics and meristics counting from a photo than the real fish.
is it mandatory to deposited any specimen (Indian) requiring an ID with ZSI, can anyone register their specimens abroad with other institutes?
Not mandatory, some foreign authors do deposit in ZSIs India so that students and other people who cannot go abroad can access their material. It is more a goodwill gesture than a rule
In addition to Marc's, it all boils down to one simple fact. Do you want to work on it to understand them better or for bragging rights? Generally people who do it for the former get a reputation and the ones who get desperate for the later are considered clowns.
The problem with our native is, most of what we know for now is either highly approximate or way too old. Taxonomy is no different from other branches of science. What seems accurate today might be rubbished tomorrow. So its all upto the individual either to rot and die blowing his own trumpet or make a base on which later generations can work on so that they don't have to waste time working from ground zero.
Well said Madhu. Marc, thanks a lot for your inputs. Thanks also to the other members for adding their views here.
Marc, expect lotsa specimens from this part of S. India . Will keep an eye out for P. filamentosus complex for you.
