BASE BODY FOR OYSTER CULTURE AND AGGREGATE BASE BODY

摘要

PROBLEM TO BE SOLVED: To provide a base body for oyster culture and an aggregate base body for which the sticking property of oyster larvae, operability, of environmental contamination resistance and recycle easiness at the time of abandonment are excellent, weight is light, density is high, an underwater settling property and underwater stability are excellent and underwater resistance is small capable of improving a space factor and the operability by being in a multi-layer parallel hanging type at the time of caring oysters and changing it to a skewed shape through one action at the time of mounting and transfer. SOLUTION: This base body 1 for the oyster culture is provided with a pair of cableways S orthogonal in a diameter direction to the center C of an umbrella-shaped disk E and the umbrella-shaped disk E is a sticking bed composed of a dent part with the excellent sticking property of the oyster larvae and a peak part for both protecting and reinforcing the dent part and is at least provided with a locking part K mutually between center cableways. The set base body sticks and cares the oyster larvae in the state of piling up and locking them or can be in the skewed shape convenient for mounting and transfer by separating them, arranging the plural base bodies along a diameter direction cableway or parallelly locking them. Further, a calcium compound, Fe group metal powder and glass fibers, etc., are added to the raw material of the base bodies.
