What percentage of sharks and rays landed in Sabah were juveniles?

Question

Accepted Answer

About 80% of sharks and 93% of rays landed in Sabah were juveniles
Early analyses of shark and ray catch landings in Sabah found that approximately 80% of the sharks recorded had not yet reached reproductive age, meaning they were juveniles. For rays, approximately 93% of those landed had not yet reached reproductive age, also indicating juvenile catches.
Catch landing surveys recorded thousands of sharks and rays
Researchers conducted catch landing surveys at fish markets and landing sites in Kota Kinabalu and Sandakan between November 2023 and December 2024. They recorded 1,748 sharks and 2,890 rays across 79 species, including 34 shark species and 45 ray species.
Juvenile sharks made up about 80% of sharks landed
In the early analysis of the landing data, approximately 80% of sharks landed in Sabah had not yet reached reproductive age. This points to juveniles being a large share of what was captured and landed.
Juvenile rays made up about 93% of rays landed
The same early analysis found that approximately 93% of rays landed in Sabah had not yet reached reproductive age. That means most rays in the landings were also juveniles.
Maturity timelines were used to frame the juvenile finding
The research notes that many shark and ray species require between 12 and 15 years to mature. With such long maturation periods, the capture of juveniles is highlighted as a major concern for long-term population recovery.
