Weighing a net of fish is just like weighing a single fish. The first step is to tare the weight of the net on the scale so it doesn't interfere with the weight of your total. Next, add the fish into the net and you will get an accurate total weight. Another great option is fish bags, similar to a net it is a soft bag with loops to attach directly to the scale. Use the same process to tare the bag and you are ready to weigh your fish.
