As soon as we see any defects in the, we start culling (I live with him and we share the same fish room). We first do a count down to make sure they have two eyes, two ventreals, a caudal, dorsal, and anal. Then we see if they are having any swim bladder problems, those with the most severe go first, and those we think might grow out of it we try and see what they do. As they get bigger, if they are crooked (especially in DT), and we immediatly toss those that are really bent out of shape. Those with messed up caudal branching (I've had a couple where the first ray was short, but stuck out of the caudal at a funky angle). The age? There is no specific aget5hat we start, it really does depend on the spawn. A smaller spawn that grows fast we could start at 2-4 weeks if we see anything funky looking. Larger spawns that take a while to grow end up being older before we can really see details of individual fish.
