Abstract:
PURPOSE: An artificial ground reef equipping with a reinforcing plate is provided to prevent the artificial ground reef from sinking by dispersing landing weight of a bottom portion and to be installed to a soft ground. CONSTITUTION: A hemispheric or rectangular artificial ground reef(10) forms a reinforcing plate(12) integrally on a bottom portion. Holes(13) are formed to the reinforcing plate within twenty five to thirty five percent in whole size of the reinforcing plate. From two to eight section shape steel posts are fixed to a lower portion of the hemispheric artificial ground reef along an outer edge of the reinforcing plate. Thereby, the artificial ground reef is prevented from sinking by dispersing landing weight of the bottom portion and installed to a soft ground.

PURPOSE: Provided is an edible and biodegradable film containing fish protein, which is excellent in mechanical properties, such as tensile strength and elongation, and vapor-permeation screening property and can be used for packing various foods. CONSTITUTION: The edible and biodegradable film contains the fish protein, wherein the fish is Theragra chalcogramma or Scomber japonicus. And the film is produced by a process comprising the steps of: extracting the protein from the fish and recovering; adding distilled water and a plasticizer to the obtained protein concentrate to produce a solution for producing the film, wherein the plasticizer is selected from the group consisting of glycerol, sorbitol, propylene glycol, polyethylene glycol, and a mixture thereof; adjusting pH of the solution to be 7.0-11.0 by using an alkali water solution and heating at 70-90deg.C to gelate the solution; antifoaming the gelated solution and molding.

Abstract:
PURPOSE: A bag net using a unit type duck as a buoyancy material is provided to promote the convenience of a work of unwinding or winding a bag net from a net hauler and a work using a bag net. CONSTITUTION: A ceiling net(11) and a bottom net are provided at upper and lower parts and have a wing net(12) integrally connected at both sides, thereby the nets forming a cod end(13) at the rear end. A buoyance material disposed on float line is formed from small-sized ducks(20) divided by units across the end of the ceiling net(11). Each of the ducks(20) is disposed between a duck connecting line connected with an upper net pendent(5) of the front end of the wing net(12) and the float line by a shackle and a hook.
