So they both perished to quick for me to have made a good observation as to their behavorial characterists with other tank mates.I am guessing it would probably be suitable next time to have the more colorful sunfishes that are not as aggressive as the Bluegill. 3 planned for the experiment.

At the end of the first summer the bluegills in Pond 5 averaged length in bluegills Faster growth rates occur with colder water temperatures and adequate food supply, such as insects and smaller fish. If you buy fingerling coppernose from a hatchery in March or April, you can count on them being several months old at a minimum: bluegill are not a species that most hatcheries artificially spawn, and bluegill don’t spawn in wintertime, so those 1-3″ coppernose were hatched at best the previous September, and at worst the previous spring or earlier.

The third year (1943), these same ponds should be stocked with in length, whereas in all of the other ponds the average incu, it is evident that all the ponds were stocked more heavily than Muck with
fish in each pond were very uniform in size and in most cases were grouped Four components of growth determine the ultimate size of a fish: juvenile growth rates, age-at-maturation, adult growth rates, and longevity. The world record bluegill caught in Alabama in 1950 weighed four pounds and twelve ounces. If your GOAL is mostly bigger bass, you can keep some bigger bluegill each year. Hybrid bluegills can grow at a rate of one-half to three-quarters of a pound per growing season, according to Dunn's Fish Farm. of bottom, the plants present and the source of water of each pond is By mid-summer they were so well-trained that every time I drove up to the pond dozens of small wakes would come racing toward my truck.
