Abstract
The significance of large siluroids in dynamics of riverine fish catch
composition pinpointed the need to appraise that i) fisheries; ii) status in
riverine fisheries; and iii) factors influencing their fisheries with special
reference toAorichthys seenghala (Sykes). The investigations were carried out
in the middle stretch of Ganga river system around Allahabad. The study
concluded that, although, catch of large siluroids had declined but their share
in riverine catch increased. The same was true for A seenghala. The increase
in fishing intensity in A seenghala breeding grounds was one of the evident
indicators of fishing stress on the fish. Strong seasonality was observed in its
catch over the year. The wanton killing of breeding population during premonsoon
and juveniles during post monsoon may be attributed for this
seasonality and decline in its catch. The fishing stress needs to be diverted
through some more lucrative option to save its fisheries. Collection of young
ones from the nest, during breeding months and their subsequent culture may
be one of the conservation measures. It would also generate additional
employment for fishers and defer wanton killing of brood stock.
