339 Bull Shark life history assignment 339 Wildlife Techniques gt Marking animals I Permanent semipermanent tags collars some radio telemetry collars tattoos bands toe clipping PIT tags Bird banding Small tag in ear O Try to make the same color PIT tag O Passive integrated transponder gt Think a microchip like in dogs I Nonpermanent Dyes hair clipping toenail clipping drop off collars I Low tech tracking Mark and recapture of individuals O Small mammal trapping on a grid O Recapture or harvest of a banded bird O Allow tracking of movement I High tech radio telemetry Collars backpacks O Hiking with reception GPS collars O Allow location frequencies all the time Q Physiological information from the animal as well Doppler Radar non invasive O look at population size as a whole O not for individual based study CLICKER QUESTION GPS collars can be used to A Track movements of individual animals B Monitor heart rates C Monitor body temps D All of the above 0 v Fisheries gt An exploited population of aquatic animals I Notjust fish gt Broader view I Aquatic biota interacting with the environment gt Three interacting components I Biota Aquatic plants amp animals I Habitat On land amp in water Humans Recreation amp commercial gt Important 29 billion people rely solely on fish for protein 200 billion pounds per year jobs recreation other industries Aquaponics Aquarium Research gt The worlds largest fishery is the Peruvian Anchovies Anchoveta gt Goal of Fishery Management Gather information amp apply knowledge to Sustainable use O Commercial harvestuse O Recreational opportunity gt Fishing is one of the first activity children can do at a young age O Aquarium trade Conservation of biodiversity O Big picture so much unknown Human health O Mercury loads in fish O Over 1 part per million O Much of mercury poising comes from china and India air pollution gt Data collection Passive capture Gill nets Fish come to the trap Trap fyke nets O Calm water O Like a maze Long lines pot or catfish traps O Like tuna or mackerel O Careful about by catchsomething you don t want is caught Active capture Seining O Beach seine gt Likecorrallingfish O Purseseine gt Lake gt Commercial gt Weighted bottoms that are closed off gt Dolphins used as indicators as location for tunacausing much of dolphin by catches O Stream seines gt Go through a pool O Trawl gt Big and small gt Net behind a boat gt SSS gt lots of damage to ecosystems O electrofishing gt boat gt barge gt backpack ANG LING is what type of capture a ac ve b passive c both d nehher Passive methods for fish capture include a electrofishing b seining c gill net d all of the above Can body mass be used to age a fish false I Non capture Hydroacoustics O SONAR Creel survey O Ask anglers what they got

gt 2012 West of Fort Collins I burned down to Pourder River I huge slope that rain poured silt into the river surprisingly no harm on the fish I pH changes in water caused selective harm gt 2013 100 year flood I seriously damaged fish relative to 20009 Test questions gt Hybrid vigor I Generally don t reproduce or reproduce successfully I Less energy going to repro and more energy towards flesh Increased growth gt Wildfires are the primary reason why bighorn sheep populations in northern C0 are declining F gt Population size decreases by both deaths and immigration F gt T One of the common errors in wildlife management is failure to evaluate the results of the management action gt F Native Americans drove bison off cliffs to hunt them and made them go extinct as a result gt T Elephants are listed as vulnerable on the UNIC International Union for Conservation of Nature redlist F A bear is more r selected than a rabbit A Big game includes mountain lion and black bear in CO B
