Welcome aboard MW!

I have two ideas for you to try.  Both use a corn Meal based fish coating.  I assume since you will be traveling with an experienced fisherman, you will have no trouble catching fish. 8-)

Breading
1/2 - cup of organic corn meal
1 t - sea salt
1/2 t organic garlic
1/4 t kelp powder
Makes enough to cover 6 small catfish fillets

In a medium pan cover the bottom with about 1/8 olive oil, do not burn.

Method 1 - Coat fillets in breading then into egg wash (made from whole eggs fromt eh egg store) and then back into the breading.  Place in pan and cover

Method 2 - Coat damp fillets in breading and put into pan.

Let me know which one you like you will find them in the oven to test.  ;)

Love fb
