A marine conservation tool for culling kina - a native sea urchin that grazes on kelp. The overfishing of lobsters and snapper in the Hauraki gulf - kina's only natural predators - has caused a catastrophic boom in the kina population, and resulting decimation of coastal habitats. While healthy kina must be collected, malnourished kina found in barrens (ecological dead-zones left behind by kina herds) must be culled as part of population control. Because conservation divers often use snorkels, they are limited to depths of 5 meters, beyond which repeated dives are exceedingly taxing. The kina lance aimed to extend this effective range down to 8m depths, and allow kina to be culled without diving at shallowed depths, thereby reducing the workload for frontline conservationists.
