Biologists now recording high numbers of tumours in fishes  

Dr. Jemimah Etornam Kassah, a Fisheries Scientist and lecturer at the University of Education, , has sounded the alarm on the adverse effects of climate change on Ghana's fisheries sector. Speaking at a media forum organized by the (GPHA), Dr. Kassah highlighted alarming trends such as increased incidents of tumours in fishes, signaling significant disruptions to the ecosystem.

According to Dr. Kassah, the rise in temperatures, a consequence of climate change, poses a threat to the reproduction and survival of juvenile fish and hatched eggs. She explained that coastal upwelling, vital for fishing in Ghana, could be compromised by high temperatures, leading to diminished reproduction rates and survival of juvenile fish.

Furthermore, Dr. Kassah pointed out that warmer temperatures cause fish to migrate to colder or deeper waters, creating challenges for artisanal fishermen who struggle to reach them. This migration pattern has led to conflicts between artisanal and industrial fishermen, exacerbating tensions in fishing communities.

Dr. Kassah also underscored the impact of climate change-induced sea level rise and storm surges, which have already resulted in the disappearance of fishing communities along the coast. She warned that more coastal communities, particularly along the eastern coast, are at risk of similar fate if urgent action is not taken.

Highlighting human activities as a significant contributor to environmental degradation, Dr. Kassah lamented the indiscriminate disposal of pollutants into water bodies and oceans. She emphasized the need for concerted efforts to curb such activities to safeguard the ecosystem and protect consumers at the top of the food chain.

In conclusion, Dr. Kassah urged stakeholders to prioritize sustainable practices and take proactive measures to mitigate the effects of climate change on Ghana's fisheries sector.
