A method and apparatus for separating the organic membrane portion of waste egg shells from the hard inorganic mineral portion thereof, so that each can be used or further processed as desired, thereby addressing the environmental and economic issues associated with disposing of waste egg shells. The membrane and shell are separated by first processing waste eggshells so as to yield small waste eggshell particles. During this processing, the waste eggshell particles are at least slightly abraded, whereby the linking structure between the membrane and shell is at least partially disrupted. Thereafter, the waste eggshell particles are conveyed to a device, which isolates the two components based on their size and weight differences. The methods listed above can provide products from the eggshell waste including precipitated calcium carbonate, membrane, protein, amino acids, collagen and other important components.

A system for reducing trawl bycatch through the use of a “flying”, “steerable” element of a towable or trawlerable fishing net, consisting of one or more hydrofoils at the mouth of the net, which maintains either a consistent height over the seabed or a pre-determined depth in the water, semi-autonomously. This negates the need, per the prior art in trawling and fishing technology, for heavy rollers on the bottom of the net, or heavy side “doors”. The present-day use of prior art ruins the ecosystem directly through physical damage to coral, sea bed hatcheries, etc., and indirectly by requiring increased fuel use on the trawling vessel and thus creating more emissions. This invention addresses those problems providing a better, cleaner and less destructive technology for fishing.

The invention discloses a smelt artificial propagation method. From the early June, the fodder containing more fish meal protein is used for the feeding of female parent fishes. While from the middle of September, the female parent fishes are fed on the fodder containing spirulina powder and aluzyme. After the parent fishes enter the gonad mature period, the better mature female parent fishes are selected and cultivated after the estrualization, and the sexually mature male parent fishes are selected and cultivated after the estrualization. After the cultivated parent fishes reach more than 60 % gonad maturity, the water temperature of a decorporation pool is dropped continuously for 2 days with the decline of 2 degree each day. Afterwards the constant temperature is kept for 4 to 6 days. During the ovulatory period of parent fish, the ovums and the sperms are artificially collected every two days. The dry artificial insemination method is used to obtain a germ cell, and the germ cell is put in a hatchery pond for breeding. With the invention, the smelt sverage absolute fecundity and the fertility rate can be enhanced, and a great number of fry can be obtained in each breeding. The scale of artificial propagation is increased, and the labour intensity of the artificial propagation is reduced. Thus a foundation for the large scale artificial culture of smelt is established.

A method for establishing a clam bed includes raising clam larvae in a captive environment in which they are provided with adequate food and habitat requirements, and kept isolated from predation by natural predators. The clam larvae are maintained in this environment during the first larval stage, referred to as the trochophore stage of development, when the larvae are particularly vulnerable to mortality. During the next stage of development, the larvae are called veligers. The developing larval clams are released, preferably in large numbers (saturation spawning) at any time during the veliger stage of development, i.e., the generic stage following the trochophore larval stage and which includes the sub-stages of straight-hinge veliger, umbonate veliger, and pediveliger. Preferably, the entire process prior to release in accordance with the invention is carried out in a closed system, to significantly reduce possible exposure to contaminants and/or harmful predator larvae/parasites, in addition to larger animal predators. A mobile floating hatchery/nursery facilitates implementation of the method by providing the captive environment, and allowing transfer of the veliger clams to a seeding site containing the prospective clam bed.
