Introduce alternative sources of bait to replace the use of marine and freshwater mammals
Overall effectiveness category No evidence found (no assessment)
Number of studies: 0
Background information and definitions
The practice of using marine and freshwater mammals as bait is widespread and affects a range of species (Mintzer et al. 2018). Introducing alternative sources of bait (that do not negatively impact other species) may reduce hunting pressure. For example, fish scraps and oil and bovine viscera were found to be effective alternatives to dolphin products for attracting fish (Sinha 2002, Beltrão et al. 2017).
