azteca that is a fabulous slide deck you posted. I wish we could hear the audio that went along with these slides. I bet it is a treasure trove of real life knowledge and experience. I wonder if anyone in WI is still growing SFS for the bait industry on a larger scale using the lessons learned here?
Bill Cody, do you understand how they are making these cedar spawning structure? Where are the crevices, just the space in between the cedar planks? They indicate a certain size square was preferred but didn't mention a preferred gap size. If the cedar squares are 2-5mm apart, how do the eggs get so far in between the squares? The fish can't swim in that crack!!? Maybe the current floats the eggs that far in?
I note current was helpful and I see that as a missing thing in my pond as well. SFS orient immediately to any moving water in my pond as well.
It could be that my black plastic cardboard squares were not accepted as egg laying structure due how smooth the surfaces were and not due to gap as gap size was similar and orientation very similar to what was in the pictures in that slide show. Probably (guessing) the cedar (wood) squares gave some added texture/roughness for depositing eggs.
I will experiment with rough sawn cedar vs smooth cedar and other crevice structure. I had added pallets and put a car tire with plenty of tread left under the deep end of the pallet to help keep it level on my sloped banks. I assumed the SFS may have used the crevices in the tires as spawning sites but have not pulled the tires yet to see for sure if eggs were laid there.
