The chemical composition of bait raw material and the use of algae as an antidote in bait were examined, as well as fishing experiments were carried out. In connection with the project, an application machine was designed and built, and experiments carried out with it in the spring of 2007 ended with application of 97%. The use of algae as an antioxidant in baits was not very successful. The bait was quite stringy at the very beginning of the storage experiment, so most likely the algae did not work properly. Ice packs with vitamin C seemed to offer some protection, although vacuum packaging was the most important. A number of experiments that were carried out on the bait were aimed at comparing the bait with conventional baits made of the same material. In general, less power was obtained with the bag bait, which can be attributed in part to storage, but storage of bag bait requires more effort than conventional bait. These experiments are aimed at checking whether the bag bait has a repulsive effect on fish that approach it. When interpreting the results, however, it must be kept in mind that raw materials can be used in bag bait that cannot be used in traditional bait, better utilization of bait raw materials is achieved and it is probably best that the bag bait goes frozen into the sea. Towards the end of the project, fishing trials indicated that bag baits produced similar catches to conventional baits. In the last fishing trip that took place in November 2006, a better haddock catch was obtained with bag bait than with regular bait, but a flaw in the setup of the experiment somewhat diminishes the veracity of the result. In addition, bag bait supplemented with vitamin C gave a slightly higher catch than bag bait without vitamin C.
