Ok, so I get the usual responses out of the way, I have two master scientists, level 3 farming. The tribe has learned how to fish out of the ocean, but I haven't gotten anything out of the lagoon. I keep trying to put the two in the lagoon and it tells me they see something swimming, but they are "enjoying the lagoon". What am I doing wrong. (Obviously I haven't gotten the puzzle even though they can fish...)

How skilled are your villagers?

Sorry I didn't include the Spoiler....

All of them? or any one in particular....

The scientists (2) and one master doctor

If you want the spoiler... it has to be a Master Farmer to catch the strange fish.

DOH.

will a villager that fishes boost their farming skills or will they need to harvest the field?

Any "food getting" activity will increase farming skill
