The invention relates to a composition for attracting and retaining fish in an area of an aquatic medium. This composition comprises an active mixture constituted by at least one active element chosen from among monoalkylamines, dialkylamines, trialkylamines, polyamines and the oxides thereof, e.g. monomethylamines, dimethylamines and trimethylamines; at least one active element chosen from among the amino acids and amides, e.g. lysine and/or urea; optionally ammonia; and optionally an active element chosen from among hydrochloric, hydrobromic, hydroiodic, sulphuric, phosphoric, formic, myristic, lactic, butyric, acetic and caproic acids, provided that the mixture contains ammonia when the element of the first group is a trialkylamine. These compositions can be used in the form of solutions, dispersions, granules, powders, etc in different fishing techniques. It is also possible to include these compositions on appropriate adsorbing or absorbing supports. |
