How is overfishing still a problem? Why hasn't farming solved this issue?
Overfishing remains a problem despite aquaculture, also known as fish farming, due to various factors.
Limited space: Aquaculture faces spatial constraints, as suitable coastal areas for fish farming are limited. This restricts the scale of production and the ability to meet the increasing demand for fish protein.
Environmental concerns: Fish farming can have environmental impacts, such as nutrient pollution from feed and waste, disease outbreaks, and habitat degradation. These concerns limit the expansion of aquaculture and may reduce its sustainability.
High costs: Aquaculture can be an expensive industry, requiring significant investments in infrastructure, feed, and labor. This makes it difficult for small-scale farmers to enter the market and compete with larger commercial operations.
Illegal fishing: Illegal, unreported, and unregulated (IUU) fishing continues to contribute to overfishing, undermining conservation efforts and reducing the effectiveness of aquaculture in replenishing fish stocks.
Consumer preferences: Consumers often prefer wild-caught fish over farmed fish due to perceived differences in taste and quality. This preference can limit the demand for farmed fish and make it difficult for the industry to fully alleviate the pressure on wild fish populations.
