Salmon Variety

Silver Salmon in the Oceans, Red Salmon in Rivers

In real life Salmon spend most of their lives in ocean and only swim up rivers to lay their eggs and then die on the way back. When they're out at sea they look very different from when they're spawning in freshwater:In Minecraft the salmon in rivers should continue to resemble spawning sockeye salmon with their red bodies and green heads, but the salmon mobs that are in ocean biomes should resemble ocean-going sockeye. The salmon item should also have two functionally identical variants for each of the mob variants, with the texture for the ocean-going item having silver colouring and without the hump and hooked jaw that real male sockeyes have when spawning.
