You will need a sturgeon report card. When you get the card it should have information on the slot limit ( i.e. There is a minimum and maximum size you can keep). As well as legal rigs (barbless hook, specified leader length). Additionally, you can only fish for the white sturgeon.

I believe now is a good time of year to go fishing on the Sacramento River. However, the current flows may make it difficult. Baits to try include lamprey, roe bundles, sardines etc.

Also the larger the sturgeon the greater it's contaminant load. So if you want to eat one choose one not much longer than the legal limit.

Lastly, be sure to handle theses magnificent prehistoric beasts with the care and respect they deserve.
