Yes, blue fins plus dorsal profile says T.khudree
, the image of the dead fish also resembles this species. However, I wouldn't be able to comment on whether these are hybrids or not, its almost impossible IMHO.
I find the dorsal profile of T.malabricus
to be quite different, I will mail you pics of what I see/think the difference is.
Some information on Indian Tor
Species of Tor known from southern India.
Tor remadevii (Humpback Mahseer)
- Upper Cauvery in Tamil Nadu, Kerala and Karnataka. Critically Endangered. Unlikely to be ever encountered in the trade.
Tor khudree (Blue-finned Mahseer)
– Originally from the Krishna river in Maharashtra & Karnataka. It has since been introduced into dozens of rivers all over India and a few locations outside of the country as well (Papa New Guinea, Laos etc). This act, IMO, has only created more confusion.
Additionally, there are many claims (accusations?) that the introduced fish are khudree*putitora/tor hybrids which obviously makes it worse. I have seen a few of these alleged hybrids in fish markets here and they look nothing like Tor
, almost discus shaped and terribly malformed fish. I also got a few pics of the broodstock used in the breeding program and they looked no better, I lean towards believing the hybrid accusations based on this. Bycatches are exported on and off.
Tor malabaricus (Malabar Mahseer)
– Middle reaches of westflowing Rivers in Karnataka, Tamilnadu and Kerala. Collected very often and exported. There is a breeding program in place for this species as well.
There is also T. kulkarnii
from the Godavari River Drainage (Maharashtra) which was described as a dwarf mahseer. Validity is unknown at the moment, I made a few attempts to collect the fish from the type locality but was told it hasn’t been seen in many years.
Tor from the northern regions
Tor tor (Red-fin Mahseer)
– Commonly collected from West Bengal (especially between the months of November and February) for the trade. It has a large distribution extending down to central India. I’ve encountered multiple 'types' (deep body, slender body, red fins, yellow fins etc) of this species including a golden one that I got from central India recently.
Tor putitora (Golden Mahseer)
– Need I say more?
– A dwarfish species, maxes out at around a foot. Found in the Ganges and Indus drainages (north-northwest India). Never been in the trade but a cool fish for the hobby IMO. Considered to belong to the genus Naziritor
- I have what I think could be T.mosal
, one 'type' from Arunachal Pradesh and another from Assam (with minute differences). I believe this is a species with a slender body, an elongate snout and a very prominent mid lateral stripe.
There are three other nominal species, T.barake,T.mahanadicus
that I have no experience collecting or keeping.
