To support an ecosystem-based approach for fisheries management, EO images with global and daily systematic coverage with high-resolution images can help in identifying potential fishing zones and to assess fish stocks. They help assessing and understanding changing abundancy and spatial distribution of exploited fish stocks. Therefore, they analyse various key environmental parameters that can be detected with satellite remote sensing. This includes sea surface temperatures (SSTs), sea surface height anomalies, and sea surface colour revealing the abundance of chlorophyll a. This relates to phytoplacton production that is directly related to total fish landings. Additionally, EO can detect harmful algal bloom. A further threat to sustainable fish stocks management are illegal fishing. Where localization of licensed fishing vessels and fleet management services are supported by EO to avoid overexplotation and enable recovery of fish stocks. EO complements identification, detection and tracking of vessels with SAR and optical remote sensing.
