Lekbeståndsbiomassa

Lekbeståndsbiomassa refers to the total weight of fish biomass that is capable of reproducing within a specific body of water. This term is crucial in fisheries management as it represents the reproductive potential of a fish stock. A healthy lekbeståndsbiomassa is essential for maintaining sustainable fish populations. When the lekbeståndsbiomassa is sufficient, it ensures that there are enough adult fish to produce the offspring needed to replenish the population in subsequent years.

Factors influencing lekbeståndsbiomassa include environmental conditions, such as water quality and habitat availability, as well as fishing pressure. Overfishing can significantly deplete lekbeståndsbiomassa, leading to a decline in recruitment and, consequently, smaller future populations. Conversely, effective management strategies that protect spawning grounds and regulate fishing can help maintain or increase lekbeståndsbiomassa. Monitoring and estimating lekbeståndsbiomassa are therefore key components of stock assessment, providing valuable data for setting quotas and implementing conservation measures to ensure the long-term viability of fish populations. The concept is directly linked to the concept of spawning stock biomass (SSB) commonly used in international fisheries science.
