Native Fish Species Restoration with Remote Incubators Team

Native Fish Species Restoration with Remote Incubators Team Leader: Parker Burton Team Members: Cailin Penberthy, Ruth Reeber, Nora Sedgwick, and Ujjwal Shrestha Client: Dr. Ed Galindo of the Aquaculture Research Institute

Rethinking Fish Restoration • Project Definition: Increase native fish survival with hatchery like success rates, while maintaining wild fish, using incubators. • Problem Statement: Optimize the current incubator design for three areas of implementation and ensure that the designs can be easily and inexpensively reproduced.

Weir Whitlock-Vibert Box Filter Inlet Outlet Divider

Fulfilling our Client’s Needs • • • Models for different situations Easy to replicate and repeat High mobility and low weight Environmentally friendly Transportable to multiple locations

Simulating the Flow • Common denominator: divider configuration ▫ Divider length ▫ Number of channels ▫ Width of channels • Modeled in Solid. Works ▫ Same base geometry ▫ Same flow rate at inlet

Designing the Flow Path

Selected Design • Uniform flow through main section • Slower flow near exit

In-Stream Design • Low profile • Non-intrusive design • Collapsible

Streamside Design • Inconspicuous • Large capacity • Semi-permanent

Demonstration Model • Representative of real models • Self-contained • Teaching model

Validating our Models • • • Initial flow testing Formaldehyde testing Destructive testing Cargo space constraint Live test: Paradise Challenge incubator
