A Significant Decline in Seal Captures
The recent statistics from the Sealord vessels indicate a notable decrease in the number of seals captured. This reduction is a positive sign for marine conservation efforts and reflects the effectiveness of measures taken to protect marine life. In the 2023/24 fishing year, only 49 seals were captured, compared to 68 in the previous year. This represents a decrease of approximately 30% in seal captures.
The Surge in New Zealand Fur Seal Population
The New Zealand fur seal, also known as the kekeno, has experienced a significant population surge in recent years. This remarkable increase has caught the attention of conservationists and researchers alike, prompting a closer examination of the factors contributing to this growth. * Historical Context
- The fur seal population was estimated at around 200,000 in Conservation efforts have been in place to protect these marine mammal* Current Population Estimates
- Recent studies indicate a substantial increase in number The Department of Conservation has not yet updated the population estimat## Factors Contributing to Population Growth
Several factors may be contributing to the burgeoning population of New Zealand fur seals.
The company has been monitoring the situation closely. ## The Rise of Kekeno Seals
The kekeno seal population has seen a significant increase in recent years, leading to a surge in seal captures by New Zealand fishing vessels.
Sealord has implemented a series of measures to mitigate this issue. ## Initiative 1: Net Modification
- Sealord has redesigned their nets to include larger mesh sizes, allowing smaller fish to escape while retaining the target catc* The modified nets have been tested in various fishing conditions, showing a significant reduction in seal entanglemen## Initiative 2: Timed Fishing Operations
- Fishing operations are now scheduled during times when seals are less active, typically during the da* This strategy reduces the likelihood of seals being caught in the nets, as they are less likely to be at the surface during these time## Initiative 3: Seal-Safe Fishing Zones
- Sealord has designated specific areas where fishing is restricted to minimize seal by-catc* These zones are based on seal population densities and migration patterns, ensuring that fishing activities do not overlap with critical seal habitat## Impact and Results
- The implementation of these initiatives has led to a noticeable decrease in fur seal by-catch incident Data collected from fishing operations show a reduction in seal entanglement by up to 40%.
The Hoki Season: A Feast for Fur Seals
Cook Strait, a narrow passage between the North and South Islands of New Zealand, becomes a bustling hub for fur seals during the hoki season. This period, marked by the abundance of hoki fish, attracts these marine mammals in large numbers. * Fur seals congregate around fishing vessels

The hoki season is a time of plenty for the fur seals, as they gather around fishing vessels to feast on the abundant supply of fish. This unique interaction between humans and wildlife has caught the attention of researchers and conservationists alike. ## Sealord’s Innovative Approach
Sealord vessel the Rehua has taken a proactive approach to studying these fascinating creatures.
Introduction to Seal Depredation Management
Seal depredation on fisheries has been a longstanding issue in New Zealand, prompting the need for innovative solutions. Sealord, a leading fisheries company, has recently taken a groundbreaking step by implementing Seal Exclusion Devices (SEDs) for the first time in the country. This initiative marks a significant shift in the approach to managing seal populations and protecting fish stocks. Innovative Approach: Sealord’s adoption of SEDs represents a novel strategy in the fight against seal depredation. First in New Zealand: This marks the first instance of SEDs being used in the country, setting a precedent for future conservation efforts. ## Understanding Seal Behavior
The choice to target male seals is rooted in scientific research on seal behavior. Studies have shown that male seals are more likely to venture into fishing areas, making them prime targets for SEDs. Male Seals and Fishing Areas: Research indicates that male seals are more prone to entering fishing zones, increasing the risk of depredation.
