Assessing growth performance and survival of wild shad Tenualosa ilisha fry in two earthen ponds with different feeding regime: A new insight for conservation

The present study describes the rearing and growth performance of Hilsa (Tenualosa ilisha) fry in experimental trial performed earthen pond ecosystem located adjacent to river Rupnarayan for developing in-situ protocol collected from wild sources. seed was during May, 2020 stocked two different ponds. One ponds provided with artificial feed another fed chicken offal raise production zooplankton. Routine monitoring water soil quality parameters as well other biotic communities like plankton understand dynamics ecological conditions relation changes length weight. results PCA between sediment specific fish indicated strong positive loading available nitrogen, phosphate free calcium carbonate, while moderate observed percentage silt. Interestingly, it is that survivability rate approximately 80% both natural considerably However, higher juveniles were 2 phytoplankton density (9120cells/L) than 1 having lower (920cells/L) at end experiments. comparable Based on this evident (especially zooplankton) has induced better possible incorporation live along formulated might trigger Hilsa. provides new insight field based approaches successful conservation threatened Indian waters.
