“Threats
The biggest threat to Northern Abalone in Canada is illegal harvest. The species is vulnerable to over-harvest because it has a short dispersal period, slow growth, long lifespan, late maturity, and sporadic or low recruitment. The species is also vulnerable because mature individuals are sedentary and tend to gather in shallow waters that are easily accessible to illegal harvesters. The abundance of Northern Abalone has been significantly reduced due to illegal harvest, which also reduces the species’ reproductive potential by removing large mature abalone and leaving remaining mates too far apart to successfully spawn.
Other threats to Northern Abalone include low recruitment, predation by Sea Otters where the two species co-exist, and habitat loss and degradation in localized areas resulting from development.“ Posted 5 years ago
