Rotting Carp Could Become Fertiliser


A Port Lincoln business who uses the fish waste from local tuna and kingfish farms, could have the answer to SA’s potentially millions of tons of rotting carp corpses.

SAMPI use fish waste to make organic fertilizer and have recently undertaken a trial alongside researchers from Curtin University, to use carp as an alternative.

The project will investigate the logistical and economic feasibility of a range of possible outcomes for the large volumes of carp biomass expected from the possible release of Cyprinid herpesvirus 3 (CyHV-3) for carp biocontrol in Australia. Initially, laboratory based processing trials will be conducted on carp at varying stages of deterioration. Processing data and efficiencies will be documented, compositional and other analyses conducted on the final products and preliminary market information/feedback collected. Commercial-scale trials of any processes that produce usable products from dead carp will then proceed. The project will finish with a detailed cost-benefit analysis of possible processes including attention to harvest strategies and logistics at various locations.

There are currently 12 research projects underway, which will inform the final list of recommendations made to the Australian Government later this year.

The coordinator of the National Carp Control Program is calling on anyone who has alternative ideas on how to economically and productively use the carp biomass to get in touch.

Operating through the Fisheries Research and Development Corporation (FRDC), the $15 million NCCP will provide a detailed recommendation to Australian governments on the suitability of biocontrol measures in December 2018.
