The But as the sportfishing industry began to lag, due to the distractions of technology and regulations, Bartosh has looked to diversify. Output restrictions require farms to have settling areas to remove solid wastes, though soluble phosphorous in the effluent cannot be removed economically - hence reductions in feed are needed to address the problem.

Some steelhead trout may spend several years in the ocean before returning to spawn, while others may only spend a few months in salt water before returning. The feed pellets, made of fish meal (80 percent), fish oils and grains, provide nutritional balance, encouraging growth and product quality, and are formulated to contain approximately 50 percent protein, 12-15 percent fat, vitamins (A, D and E), minerals (calcium, phosphorus and sodium) and a pigment to achieve pink flesh (where desirable).

Raceways provide well-oxygenated water and water quality can be improved by increasing flow rates; however, the stock is vulnerable to external water quality, and ambient water temperatures significantly influence growth rates. Gutting can be done by hand or by machine, and it is preferable Since 1874 it has been introduced to waters on all continents except Antarctica, for recreational angling and aquaculture purposes.
