southern fish given the elbow!

crowded_fishClimate change is expected to considerably change Australia’s marine environment with fish stocks moving further south as ocean temperatures rise, a new CSIRO report warns.

Report co-author Dr Alistair Hobday said that global warming could have positive and negative impacts on fish numbers around the country. “The southeast of Australia will experience ocean warming that will allow some fish species to move south into temperate waters,” he said.

“That could have, for example, a positive impact for recreational tuna fishermen. The negative impact would be that southern fish species are pushed too far south, meaning their numbers will decline because they will not have a suitable habitat to survive in.”
