Discoveries in Goa & Karnataka. Part 2 - Heiko BleherIn the vicinity of the great water dam Haligri (known as Kelageri as well) a road crosses a tiny creek that apparently flows into the reservoir. It was my fifteenth netting location. When I was walking upstream in the slowly flowing, cloudy water with a rocky substrate two boys approached me and insisted on catching some fish for me. They caught several specimen of Devario aequipinnatus, Nemacheilus denisonii, Rasbora aff. daniconius (I’m positive that more than one, so far not described, species are being classified under this name). Later on, by the stream banks, I managed to net several species I haven’t met before during this journey – for example Puntius melanostigma (for some it’s a synonym for Puntius mahecola, despite the fact that they are two separate barb species. In 1876 Day described P. melanostigma found in the region of Wynaad Hills in Kerala and this fish has nothing to do with P. mahecola from Mahé described by Valenciennes in 1844). I found P. pookodensis for the first time. I came across P. bimaculatus there as well.

The article published in the previous issue of the magazine acquainted us with a probable evolution of parental care in fish. This text describes various types of vivipary in rays, sharks and several families of bone fishes in a greater detail. We will find out that there are significant differences between vivipary in cartilaginous fishes and bony fishes with regard to spawning and development of the embryo.
