Projected changes to freshwater fish stocks. Presented by Peter Gehrke. Key messages. Freshwater fisheries are important in Fiji!!! Increased rainfall will increase freshwater habitats in tropical regions, less in subtropics Freshwater fish production increase by 5 – 20%
Freshwater fish catches typically correlated to river flows
Barriers (waterfalls, weirs, culverts) may block retreat of freshwater fish and clams
The outcomes of climate change for Fiji’s freshwater fisheries will be determined by the effectiveness of strategies to minimise human impacts at the catchment scale.
