Squids on bedrock cannot spawn in any type of river biome, only in oceans. This is different from every other version of Minecraft, where squid have always been able to spawn in rivers (parity issue).
Bedrock should be able to spawn squid in rivers for several reasons:
1. Parity, all other platforms allow this.
2. This forces players to attempt and farm squids in ocean biomes, which is an extreme amount of work, for very very little payoff.
3. Squids already spawn very rarely, and a river already has a natural perimeter around it. Allowing players to farm ink much better than in oceans.
4. Salmon overpopulation in rivers due to lack of top predators in the form of squid.
The Minecraft Wiki states this info as if it where intended, but, we all know how reliable the wiki is at times. Creating a bug report is the best way to figure out if something is intended or not haha:]

This is Working as Intended, see MCPE-13568.
As stated by the developers in MCPE-8280, this is working as intended. In Bedrock, squid only spawn in ocean biomes.
If you'd like to suggest a change, you can do so on the Feedback site.
Also on the Nintendo switch version
