Definitions

  • the present invention relates to biodegradable artificial baits obtained from biodegradable compositions substantially insoluble in an aqueous environment, and capable of releasing attractive substances that are able to attract aquatic organisms of interest in the same aqueous environment.
  • biodegradable artificial baits obtained by biodegradable compositions substantially insoluble in an aqueous environment and capable of releasing attractive substances that are able to attract aquatic organisms in such aqueous environment.
  • the biodegradable artificial bait according to the present invention comprises a composition comprising at least one biodegradable substance of renewable origin, at least one biodegradable (co)polymer of synthetic origin, and at least one attractive biodegradable substance that is able to attract aquatic organisms.
  • the biodegradable substance of renewable origin is present in an amount of from 10 to 90 wt%, preferably from 20 to 80 wt%, and still more preferably from 30 to 70 wt%.
  • the substance of renewable origin comprises natural polymers that are able to become thermoplastic in suitable conditions of temperature and in the presence of plastif ⁇ ers.
  • Said natural polymers comprise, for example, starches, modified starches, alginates, lignins, celluloses, modified celluloses, etc.
  • the substance of renewable origin is starch.
  • the starch can derive from potato, rice, tapioca, maize, peas, wheat, and the like. Potato starch or maize starch is preferred.
  • the starch can be also modified either chemically or physically.
  • composition moreover contains at least one biodegradable thermoplastic (co)polymer of synthetic origin.
  • biodegradable thermoplastic (co)polymers that can be used as components of the artificial baits according to the invention are chosen among the following classes: a) biodegradable polymers of synthetic origin or obtained by fermentation, in particular polyesters such as homopolymers or copolymers of aliphatic hydroxyacids having from 2 to 24 carbon atoms, or of the corresponding lactones or lactides, such as, for example: - poly(epsilon) caprolactone, its grafted or block copolymers, the products of reaction of caprolactone oligomers or polymers with aromatic or aliphatic isocyanates, copolymers with lactic acid, with glycolic acid, with poly-hydroxybutyrate and poly- hydroxybutyrate-valerate; polymers of lactic acid or of lactide, polymers of glycolic acid or of polyglycolide, copolymers of lactic acid or of glycolic acid; long-chain, medium-chain, and short-chain polyhydroxyalkanoates such as,
  • polyesters derived from bifunctional acids and aliphatic diols such as, for example: aliphatic or aliphatic-aromatic polyesters such as polyalkylene adipates, polyalkylene succinates, polyalkylene azelates, polyalkylene sebacates, and polyalkylene brassilates, possibly copolymerized with aliphatic or aromatic isocyanates possibly increased in weight by means of chain extenders; such as, for example, polyethylene adipate, polybutylene adipate, polyethylene adipate-co-terephthalate, polybutylene adipate-co-terephthalate, polyethylene succinate, polybutylene succinate, polybutylene succinate-co-adipate, polyethylene azelate, polybutylene azelate, poly
  • aliphatic polyamides 6-6, 6-9 or 12 aliphatic polyamides, aliphatic polyurethanes, random or block polyurethane-polyamide, polyurethane-polyether, polyurethane-polyester, polyamide-polyester, polyamide-polyether, polyester-polyether copolymers; polycaprolactone-urethane, where the size block of polycaprolactone is between 300 and 3000 units of molecular weight and where the isocyanates used are MDI
  • gelling agents such as boric acid, borates or phosphates, copolymers of vinyl acetate in the various degrees of hydrolysis with vinyl pyrrolidone or styrene, polyethyloxazoline, polyvinyl pyridine; or polymers capable to form hydrogen bonds with starch.
  • an alkenolic homopolymer and/or alkenolic copolymer in an amount of from 10 to 90 wt% with respect to the composition, preferably from 10 to 40 wt%.
  • the preferred alkenolic homopolymer is polyvinyl alcohol, in particular with a degree of hydrolysis of between 80 and 99 mol%, preferably between 90 and 99 mol%, and still more preferably between 96 and 99 mol%.
  • the composition moreover contains attractive biodegradable substances of natural or synthetic origin that are able to attract aquatic organisms of interest in an amount of from 1 to 30 wt%, advantageously from 1 to 15 wt%.
  • attractive substances of natural origin particularly preferred are extracts of yeast, oligopeptides, mixtures of oligopeptides, amino acids, mixtures of amino acids or combinations thereof. Extracts of yeasts are particularly preferred.
  • the preferred yeast is Saccharomyces Cerevisiae.
  • the attractive substances of natural origin mentioned above may be used as such to attract aquatic organisms, even if not in the form of baits. Also in this case extracts of yeasts are particularly preferred.
  • the preferred yeast is Saccharomyces Cerevisiae.
  • the artificial bait according to the present invention has the form of a meshlike container containing extruded granules.
  • Said embodiment is particularly advantageous in fishing techniques where traps are used where the aim is to catch the fish alive without the use of hooks.
  • particularly advantageous are instead injection-moulded articles with shapes suitable for controlling release.
  • the granules obtained were then tested as regards their solubility in water and release of aroma in an aqueous environment.
