LSU AgCenter scientists have invented a new bait to help catch blue crabs. The bait works particularly well on the Louisiana blue crab but shows promise for other varieties. The crab is typically caught with menhaden fish, which can have a higher price and lower supply due to their usefulness as bait, a fish oil source, and food. The new bait uses materials such as shrimp waste, a byproduct of shrimp production, to create a low-cost alternative with recycled materials.
LSU AgCenter scientists have developed a system containing fish-attracting materials that are released over time into water through a pail container. The materials contain biochemical and natural substances effective for attracting fish but can be modified to incorporate other chemical fish attractants to further enhance the effectiveness or tune fish species specificity. The release rate can also be changed to suit a fisherman’s needs and potentially make a better catch.
LSU AgCenter scientists have developed a novel fishing lure material that can enhance fish attractants. The material is biodegradable and water soluble, so it will not cause environmental harm if lost or ingested by fish. The material is also uniquely designed to contain and slowly release fish attractants, meaning that a small amount of attractant will last longer in a given area and potentially lure a larger number of fish.
This invention is a new method and device to oxygenate water for use in ponds and waste treatment plants. A very simple and energy-efficient device is inserted into water. It distributes oxygen evenly and creates ammonia-destroying films. It does not requires commercial pressure systems to operate, thus leading to energy and equipment savings.
