OK, lets talk with the weight part. Lets do it as in a comp. Weight all the fish as for the heaviest bag, then weight the biggest carp, the biggest barble, and the biggest yellowfish.
So we take the heaviest bag with the no. of fish, that is the (weight x 10)+(No. of fish x10)=total points of comp. That is the first overall winner with the highest points. Any fish less than 150g don't count as a 10 point fish, just add it to the weight.
e.g. 20 carps kg43.500g 1 yellow kg3.250g = (20x10) + (43.5x10)
= 200 + 435
= 635 points
The yellowfish must be a largemouth, and must be over 400mm before it's weighed. All smallmouth be placed back in the dam.
Place all fish in a keepnet.
