Containment boom apparatus and methods for use in harvesting brine shrimp eggs
First Claim
1. An apparatus for harvesting brine shrimp eggs from a body of water, comprising:
- an elongated member comprising buoyant material which enables said elongated member to float at or near the surface of the body of water;
a water-permeable member attached to and positioned downwardly from said elongated member so as to enable said water-permeable member to be positioned below the surface of the body of water, said water-permeable member being configured so as to be substantially impermeable to brine shrimp eggs; and
a first reinforcement member positioned adjacent said water-permeable member, said first reinforcement member having substantially greater strength than said water-permeable member, wherein said first reinforcement member further comprises a plurality of reinforcing strips to provide additional strength to said first reinforcement member.

Abstract
Apparatus and methods for harvesting brine shrimp eggs from a body of water involving the use of an elongated member comprising buoyant material which enables the elongated member to float at or near the surface of the body of water and a water-permeable member positioned downwardly from the elongated member so as to enable the water-permeable member to be positioned below the surface of the body of water. The water-permeable member is configured so as to be substantially impermeable to brine shrimp eggs and substantially prevents brine shrimp eggs from escaping harvest as the apparatus is moved through the body of water to collect the brine shrimp eggs. In one presently preferred embodiment, the water-permeable member comprises a porous screen. One or more reinforcement members may also be included to protect the porous screen from tearing, puncture, or other damage.

43. An apparatus for harvesting brine shrimp eggs from a body of water, comprising:
-
a containment boom which is capable of encircling a plurality of brine shrimp eggs, said containment boom comprising buoyant material which enables said containment boom to float on the surface of the body of water; a porous screen which is water-permeable, said porous screen being mounted to said containment boom so as to hang downwardly therefrom and so as to be capable of being positioned below the surface of the body of water, said porous screen having a mesh size which renders said porous screen substantially impermeable to brine shrimp eggs; and a plurality of reinforcing strips applied to said porous screen so as to provide additional strength to said porous screen, said reinforcing strips being constructed of a substantially stronger material than said porous screen. - View Dependent Claims (44, 45, 46, 47, 48, 49)

50. A method of harvesting brine shrimp eggs from a body of water, comprising the steps of:
-
positioning at or near the surface of the body of water an elongated member comprising buoyant material which enables said elongated member to float; positioning downwardly from said elongated member and below the surface of the body of water a water-permeable member which is configured so as to be substantially impermeable to brine shrimp eggs; providing a first reinforcement member adjacent said water-permeable member, said first reinforcement member having substantially greater strength than said water-permeable member; providing a second reinforcement member adjacent said water-permeable member, said second reinforcement member having substantially greater strength than said water-permeable member, said water-permeable member being positioned between said first reinforcement member and said second reinforcement member; and moving said elongated member and said water-permeable member with respect to the body of water so as to collect brine shrimp eggs. - View Dependent Claims (51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64)
