The State-Fish Art Contest is open worldwide to all youth in grades K -12 in public, private or home-school, any youth group, after-school program, youth camp, scout troop, art class, or just an individual youth that wants to enter! Essentially any youth of K-12 age is eligible as long as a responsible adult reads, agrees to and signs their entry form. Read more about the State-Fish Art Contest... Survival Rate of Angler Caught and Released Largemouth Bass
Author: Brad Wiegmann, Gene R. Wilde and Kevin L. Pope
Every angler that catches a fish has to make a decision to either keep or release it. There is no harm in practicing selective harvesting when within the state or federal regulations: in fact selective harvesting can improve the quality of fish in some reservoirs. Nevertheless, if an angler releases it what are the odds of it living? One abstract that covers the survival of angler caught and released is A Simple Model for Predicting Survival of Angler-Caught and Released Largemouth Bass, Transactions of the American Fisheries Society (Volume 137, Issue 3, 2008, Pages 834 -840. Authors: Gene R. Wilde, Kevin L. Pope). Read more on survival of angler caught and released bass... Recycledfish.org The trouble with plastics: Transgender Bass!
Author: Mark Olson & Teeg Stouffer
Many soft plastic lures are made of polyvinyl chloride (PVC). Manufacturers use plasticizers, often compounds called phthalates (1), to keep lures soft and pliable. Phthalates leach out rapidly because they do not chemically bind to the PVC resin. The problem is this. Several research studies have identified phthalates as endocrine disrupters. In studies, rodents exposed to high doses of certain phthalates have exhibited changes in hormone levels. Succeeding generations of the test population have also had birth defects. The extent to which they disrupt the endocrine system is disputed and some researchers have stated that the existing research needs to be conducted on a larger sample.

Author: Brad Wiegmann
What we do today will reflect on how our children see things tomorrow. We are all stewards of our planet. We are responsible for overseeing how well it is taken care of and to lessening the negative impact on the environment. Recycled Fish takes this to heart and is looking to the future by engaging other anglers to defend our waters and make a positive impact by buying or sponsoring a Stewardship kit.

Education is the key to understanding why and what should be done for fish obviously in the state of hyperbuoyant. Dr. Hal Schramm is leader of the U.S. Geological Survey Mississippi Cooperative Fish and Wildlife Research Unit and professor in the Department of Wildlife and Fisheries at Mississippi State University. Dr. Schramm explains, “When bass and other sport fish, like crappie and walleye, are rapidly brought from deep water to the surface, atmospheric pressure is quickly reduced, the air in the swim bladder expands, and the fish is unable to maintain an upright position and swim back to deep water. This condition is called hyperbuoyant and excess pressure can be relieved by depressurizing or repressurizing.” Riparian Conservation:Benifits Land Owners and Wildlife

Author: Dan Ashe
The state of Texas began stocking largemouth bass in 1941 back when TPWD was known as Texas Game, Fish, and Oyster Commission. From 1941 through 1971 only northern strain largemouth bass were stocked into Texas public waters. In 1972, TPWD began stocking lakes with Florida largemouth bass and since then has stocked 325 public lakes. TPWD stocks Toledo Bend and Sam Rayburn almost every year with Florida largemouth bass. Florida largemouth bass are stocked to either increase the allele frequency (number of Florida largemouth bass genes) of the existing population, to supplement limited recruitment, or help recover from a catastrophic loss of fish. Florida largemouth bass are capable of growing more rapidly and reaching larger sizes than northern largemouth bass. TPWD has been successful in altering the genetic composition of bass populations through its stocking program. TPWD stocks most of its Florida largemouth bass not to increase the overall number of fish in a lake but to increase the Florida allele frequency in order to provide a population of bass capable of growing to larger sizes. In 2006 there was nearly 15 million bass requested by the TPWD management districts, with just 6 million fish actually produced and stocked. Having shortfalls between what is requested and what TPWD hatcheries can realistically produce is typical for most years. It is because of these shortfalls and total cost, that TPWD must become more efficient with its bass stockings and still obtain our objectives. Read more about stocking bass on Toledo Bend... |
