I try to create a new river with upstream of Browntrouts, rainbowtrouts and downstream with pikes, crappies, perchs but in "call guide" there is no Rainbow and no Browntrout ?

Finally, it is possible to choose the place where one put fish ?
In France a river is classified in 2 categories, the dates opening of fishing are different :
- Towards the source, first categorie, with trouts, minnows etc
- to the bottom, second categorie, with pikes, crappies etc
