Question:
"When DFG releases trout from one of your hatcheries, canthese trout be considered farm raised or are they treated muchdifferently than farm raised (e.g. fed antibiotics, growth hormones orother “unnatural” stuff)? Do the same mercury warnings apply to themas is advertised for the wild caught fish from some lakes/reservoirs?"
(Sigrid T.)

Answer:

"The fish raised and released from DFG hatcheries can beconsidered "farm raised," although hatchery rather than farm is a moreappropriate term. According to retired DFG Senior Fisheries BiologistDennis Lee, the fish are fed commercially prepared diets, typically apellet-type fish feed. Fish meal is the principal ingredient althoughfish feed usually contains some supplements such as vitamins or shrimpmeal, but no hormones. Feeds are analyzed for content and may notcontain adulterants such as pesticides. *All DFG hatcheries are routinely monitored by a staff of fishpathologists. If fish become sick, a therapeutic treatment may beprescribed using therapeutic drugs or chemicals approved by FDA for useon food fish. These are either applied to hatchery water or in the caseof antibiotics, milled into feed by the manufacturer. As far as your concerns about mercury warnings, according to Dr.William Cox, DFG Fish Production and Distribution Program Manager,mercury is acquired by fish in waters having high levels of mercury.Fish accumulate mercury by eating small invertebrates, crustaceans andbaitfish from those local waters. Larger fish that have livedexclusively in those waters may have elevated levels of mercury. Fishraised in hatcheries are fed diets free of mercury or other contaminantsand therefore are free of those chemicals at the time of planting.Health advisory warnings for affected waters are listed in our sportfish regulation booklets, according to California Department of HealthServices."

Thanks for the post, great info.

Some guy told me one time that work DFG, and said that the pellets that they feed the hatchery trout have some of the same ingredients that Berkley Powerbait has in it. Anyone know or heard of anything like this?

When I visited Moccasin creek hatchery they have a machine where you can buy fish pellets to feed the fish and those pellets smelled just like powerbait, it would make sense that they would use similar ingredients.
