Developing increased survival techniques for shellfish enhancement of two species (Clinocardium nuttallii and Mya arenaria) through implementing predator protection in Southeast Alaska

Increased sea otter populations threaten shellfish populations throughout Southeast Alaska, and necessitate innovative solutions for “grow-out” techniques for shellfish on subsistence and personal use beaches. The primary purpose of this project is to develop and implement innovative grow-out and predator control techniques using predator control blankets to maximize growth and survival for cockles and soft-shell clams on subsistence beaches adjacent to the community of Kake, Alaska.

The objectives of this JIP supported project are to: (1) work with the shellfish hatchery as they refine techniques to maximize growth and survival for cockles and soft-shell clams; (2) determine optimum installation and tending techniques for predator control blankets after seeding; (3) complete 12 months of trial grow-out period, with 4 controlled scenarios.

Additionally, The Organized Village of Kake has been engaged in a pilot study to support this work over the past 12 months, including out-planting 2 rounds of cockles. Additionally, the project will include 4 community engagement events with community residents in Kake to facilitate community engagement in pre-survey of study areas, out-planting, monitoring, and post-study survey.
