A shipping container for sea worms contains a fibrous bed of vegetable matter which is degraded by fermentation. The bed is both wetted and seeded with a microorganism in order to insure the fermentation.
This invention aims to provide a method for transport and/or storage of live baits adapted to alleviate a lose occurring in the course of transport and/or storage and to maintain a freshness of the live baits for a long period. The method according to the invention comprises making artificial muddy sand used to transport and/or store live baits. The method comprises the steps of: immersing paper products in artificial seawater to fibrillate the paper products; preparing a mixture of plants cellulose fiber of the paper product fibrillated in the artificial seawater and muddy sand of the live baits' native seashore; and forming granular artificial muddy sand containing an amount of seawater from the mixture.
The present invention provides a method for inducing gamete maturation in marine worms of the family arenicolidae and which exhibit epidemic spawning. In the method, male and/or female worms in a housing substrate (such as sand) in sea water are maintained at a temperature of 4 to 8.degree. C. for 14 to 24 days, preferably 5 to 7.degree. C. for 20 to 22 days. Spawning of the worms can them be induced either by exposure to suitable spawning promoting hormones or by raising the temperature of the sea water to 12 to 14.degree. C.
A degradable container is disclosed as containing 60 wt % to 70 wt % of a plant fiber, from 10 wt % to 30 wt % of an adhesive and from 0.1 wt % to 5 wt % of a demoulding agent, in which the adhesive is a modified urea-formaldehyde resin. A method of forming a degradable container is also disclosed as including the steps of (a) grinding a plant fiber to a size smaller than a pre-determined size; (b) nixing grounded plant fiber obtained under step (a) with a demoulding agent to form a premixed material; (c) mixing said premixed material with an adhesive into a powder form; (d) press-moulding said powder obtained under step (c) a first time under a pressure of 5-80 MPa; and (e) press-moulding said powder a second time under a pressure of 1.5-16 MPa into said container.

The present invention provides a method for the aquaculture of marine deposit feeders, such as Arenicola marina and Arenicola defodiens. The method comprises providing a foodstuff such as brewery yeast or waste from fish farms within the substrate housing the worms. The foodstuff is conveniently particulate or microparticulate to aid intimate admixture with a substrate, which is typically sand.
