Understanding Prespawn Activity of Fish and Anglers
By Mark Bilbrey
 


  A mild winter for much of North America could mean several things to anglers. The natural cold water shad kills did not happen in much of the cotenant. This has given bass an abundant forage base on which to feed in the warmer than usual winter lakes. The mild winter and warmer water could also affect the prespawn activity among bass as we approach February and spring gets closer every day. The activity of bass is primarily controlled by the temperature of the water.  


 As bass move toward the shallow areas in the prespawn it is important to read the temperature of the water. Anglers should realize that not all bass have the same urge to begin prespawn activity at the same time. Smallmouth will become active before largemouth and not all of these will become active simultaneously. Some will move shallow and back to deep as seasonal weather patterns change, while others will wait out for the perfect conditions. The prespawn activity can span a period of several weeks on any given lake as water temperatures rise from the exposure to longer periods of daylight warming and warmer temperatures and rain. The trick anglers must be looking for in the early prespawn area is the depth at which the concentrations of fish will be holding.


  It is impossible for an angler to predetermine whether or not he will catch one fish or fifty fish based solely on the surface temperature of the water.  Experience and education have taught many anglers that fifty degrees can be the magic number; however, this temperature can be good or it could be bad depending on which direction the temperature is moving.  Forty nine degrees or lower means it could be difficult to catch fish at any given time of the day. However as the temperature of the water reaches a sustainable fifty degree and the mercury trends to be moving upward the activity of fish will rapidly change. A bass’ metabolism changes when their cold blooded bodies warm up. Rapid digestion means more frequent feeding, and at a time when Mother Nature is telling them that it is nearing the time to reproduce, this activity is enhanced even more. A south wind and some sunny days when the water reaches the fifty degree range, tells many anglers to begin to fish in areas that are near known spawning areas with a hard bottom on the northwest side of the lake. The slightest variation in temperature will attract bait fish, and thus the bass.


  Wise anglers not only try to remember successful locations, but keep a fishing log each year as winter passes the torch to spring. The knowledge of air and water temperature, prolonged weather conditions, water clarity and the size and color of bait used on successful days will take hours of guesswork out of your fishing. This is what often separates the Joe's from the pros on the water. Record notes of structure from your electronics or topo map. Use your GPS to mark the location if possible. The prespawn migration routs hold important clues that will be useful throughout the year.



Prespawn anglers normally understand the importance of catch and release at this important time of the year. Sewing the seed for the future of your fishery is an important part of being a sportsman. As the bass make preparation for the spawn, please be responsible in your cull. Tournament anglers take steps to correctly maintain your live wells to protect the future of the fishery. Being both ethical and responsible is the responsibility of all sportsmen, please take the time to share catch and release habits, handling and measuring tips and live well health with new anglers.



Happy Fishing!
