DFFE: Limits South Africa Sardine Catch Amid Mass Die-Offs

• South Africa's Department of Forestry, Fisheries and the Environment (DFFE) has imposed temporary limits on sardine catches.
• The measure follows mass sardine die-offs along the South African and Namibian coasts, linked to the pilchard herpesvirus (PHV).
• Each fishing rights holder is restricted to landing no more than 25% of their outstanding 2026 total allowable catch until October 2.
• Conservationists warn that the die-offs severely threaten critically endangered African Penguins, for whom sardines are a primary food source.
• Beyond penguins, a decimated sardine population could negatively impact South Africa's ecotourism and other fisheries.

Without sufficient fat reserves, these critically endangered birds face starvation during their crucial moulting period.

South Africa's Department of Forestry, Fisheries and the Environment (DFFE) has implemented temporary restrictions on sardine catches following widespread reports of mass die-offs along the nation's coastline. These mortalities, first observed on July 28, subsequently spread to various locations across both the South African and Namibian coasts, raising significant ecological concerns.

Laboratory testing conducted by the DFFE confirmed the presence of genetic material from the pilchard herpesvirus (PHV) in sampled sardines. This marks the first recorded instance of PHV in South Africa, although a previous outbreak in Australia during the 1990s resulted in an estimated 70% reduction in that region's adult sardine biomass. While the DFFE identifies PHV as the primary explanation for the mortalities, investigations into other potential environmental factors remain ongoing.

However, Craig Smith, a senior technical marine specialist at WWF South Africa, suggests that if an additional environmental stressor were responsible, broader ecosystem impacts would likely be evident, which is not currently the case. Smith's assessment indicates that the observed patterns align with a highly virulent viral outbreak, reinforcing the pilchard herpesvirus impact as the leading cause for the unprecedented die-offs. In response to this critical situation, the DFFE limits South Africa sardine catch as a precautionary measure.

As a direct consequence of the sardine die-offs, the Department of Forestry, Fisheries and the Environment (DFFE) announced temporary sardine fishing regulations ZA, effective immediately. These regulations stipulate that each fishing rights holder is permitted to land no more than 25% of their remaining 2026 total allowable catch. This measure, announced on a Sunday, is slated to remain in effect until October 2.

The decision to implement these South Africa fishing quotas aligns with recommendations put forth by the department's Small Pelagic Scientific Working Group (SWG-PEL). This expert group convened on September 4 to assess the unfolding situation and advise on appropriate responses. According to DFFE spokesperson Zolile Nqayi, the department plans to intensify its observations of the sardine population. The SWG-PEL will then re-evaluate the situation comprehensively before the current restrictions are scheduled to conclude, ensuring an adaptive management approach to the crisis.

The mass sardine die-offs pose a severe threat to the critically endangered African Penguin population, for whom sardines serve as a vital food source. These penguins are already under considerable pressure, partly due to competition with the small pelagic fishing industry for essential prey like sardines and anchovies. Ronelle Friend, director of the Algoa Bay Conservation group, expressed particular concern over the timing of the die-offs, as they coincide with the penguins' crucial moulting season, which typically spans from late September to December.

During their moult, penguins shed their feathers and fast, requiring substantial fat reserves built up beforehand to survive this energy-intensive period. Without sufficient fat reserves, these critically endangered birds face starvation during their crucial moulting period, as highlighted by Friend. Dr. Alistair McInnes, seabird conservation programme manager for BirdLife South Africa, has noted concerning changes in penguin colonies on the south coast, including declining body mass in birds at Dyer Island and Stony Point (Betty's Bay), alongside fewer penguins recorded crossing weighbridges at the Stony Point colony. While West Coast colonies, such as Robben Island, have not exhibited similar trends, McInnes cautions that it is premature to draw definitive conclusions, although the rapid decline in numbers at Betty's Bay is unusual for this time of year.

The pilchard herpesvirus impact extends beyond African Penguins, threatening broader ecological and economic stability. Craig Smith of WWF South Africa warns that a decimated sardine population would significantly harm South Africa's economy, particularly ecotourism sectors like shark cage diving and whale watching. Furthermore, fisheries targeting predatory species that rely on sardines as a food source would likely face considerable challenges, as their populations would be under pressure from a reduced food supply.

Lawyers advising fishing rights holders in South Africa must ensure clients comply with the DFFE's temporary sardine catch limits and monitor future regulatory updates, particularly given the ongoing scientific assessment and conservationist calls for stricter measures.
