Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain trout as fish and food, relay species, aquaculture, angling rules, nutrition and cooking safety from fisheries and food sources, describe the named forms including the char alias, and distinguish trout from salmon, chars, steelhead as a rainbow trout form and trout-like fish in other families.

Trout as fish and food, several species of the salmon family, mainly in the genera Oncorhynchus, such as rainbow trout, and Salmo, such as brown trout and its sea-run form called sea trout or salmon trout, and some chars, raised widely in aquaculture and caught in recreational fishing, eaten fresh, smoked or as fillets; young trout and salmon at the stream stage are called parr. The registry alias Amemasu names the white-spotted char Salvelinus leucomaenis of Japan, a related char. Farmed trout should be cooked properly, and anglers need licences and should follow local rules on catch and release.

What it is for: Food, aquaculture and recreational fishing.

It can be explain species and life stages; relay aquaculture and angling rules; describe named forms; relay food safety and nutrition.

Distinguishing features

Salmonid

Freshwater and sea-run forms

Major aquaculture species

Popular sport fish

What it looks like

Streamlined fish with small scales, spots and often pink or orange flesh.

Physical character

rainbow trout: Oncorhynchus mykiss taxon

brown trout: Salmo trutta taxon

omega-3 content: moderate to high note - varies with diet

How it is recognised

Salmonid fish used as food

Parr, Amemasu, salmon trout, salmon trout fillet

Salmon are larger ocean-going salmonids; chars belong to Salvelinus; steelhead are sea-run rainbow trout; other trout-named fish belong to other families

What the second pass must settle

  • The registry alias Amemasu should be moved to white-spotted char
  • Should sea trout be a separate entry?
  • How should fisheries sources be linked?
