A word cloud poster of Illinois-Indiana Sea Grant’s 2017 impacts and accomplishments.

The brochure is an overview of what a fish producer thinking about small-scale fish processing needs to know. The overview includes training requirements, available facilities and highlights of select farmers who have gone through the process.

Aquaponics: Farming Fish, Growing Greens teaches STEM through aquaponics, a water-based agricultural system that combines aquaculture and hydroponics. This 9-12 grade curriculum was designed to be used along with an onsite aquaponics system. Curriculum topics include an Introduction to aquaculture, fundamental parts of an aquaponics system, the nitrogen cycle, water quality, population dynamics, our modern food system and more. Lessons were developed to build on each other and be delivered in sequence but can also be used individually.

We use research, outreach, and education to bring the latest science to Great Lakes communities and their residents. Here is a quick summary of IISG impacts in the region for educating interested parties about what Sea Grant does.

Small- to medium-scale aquaculture businesses in the USDA North Central region face marketing challenges. In this publication, Purdue and Illinois researchers use a step-by-step approach to advise farmers how direct marketing can shorten the supply chain and help them find new customers willing to pay premium prices.

This overview introduces a novel method for producing high-quality protein for larval fish diets, targeting feed and ingredient manufacturers. It outlines the challenges of indoor fish rearing using recirculating aquaculture systems (RAS), particularly the difficulty larvae have digesting traditional dry feeds. The proposed solution uses protein hydrolysates—pre-digested proteins made more accessible through hydrolysis with species-specific digestive enzymes. This approach improves nutrient absorption and growth performance. Notably, the method uses invasive fish species as a sustainable protein source and applies enzymes from the target species for precise, efficient hydrolysis.
