Developing Commercial-Scale Low-Salinity Culture Protocols For Gulf Killifish, Fundulus Grandis, Brittany Morgan Chesser

Theses and Dissertations

Gulf Killifish Fundulus grandis is an estuarine species used as a live bait for marine sport fishes, native from Veracruz, Mexico, along the Northern Gulf of Mexico coast, to the eastern coast of Florida. Culture protocols are established, but Gulf Killifish have not been fully adopted as a commercially produced species by producers, possibly due to economic efficiency and needs for advances related to inland production. Therefore, production methods from spawning in recirculating aquaculture systems (RAS) to grow-out to market size in earthen ponds were examined. Increasing broodstock density or spawning substrate surface area did not increase egg production in …
