"Grow and protect your fishery with the Mossback Fish Habitat Spawning Bundle. Perfect for ponds where spawning substrate is lacking, this set of 3 artificial structures provides a simple solution: simply place them 5'-10' apart along a likely stretch of near-shore contour to attract spawners. Each Spawning Bed has nine 46""L adjustable limbs that can be arranged as needed to provide cover; the V-shaped arms are textured to collect sediment and promote algal growth. Plus, the system's flexible design reduces snags when it's time to hit the water with your rod in hand. Each unit features a 20""H pipestand and round base pan that can be filled with gravel (not included) to anchor in place. Also provides fishable structure all year long.
