Otter's Soft Milking Eggs are the most realistic eggs available, and the trout, steelhead, and salmon agree. These eggs have the same consistency and texture as real eggs. While there are many other egg patterns on the market, none are "soft and milking." Others are made of hard plastic or epoxy, and do not exhibit the milking characteristic of real fish eggs. The Otter's "Soft Milking Egg"® patterns duplicate real fish eggs when drifting in the water current. Due to numerous species in the rivers, Blue River Designs, developed and created various color and size combinations to duplicate realistic colors for the different species of trout, salmon, and sucker spawn eggs. When fish eat these, they just don't want to let go. You will out-fish everyone on the river with these soft, chewy, realistic eggs. They are available in 6mm size (salmon egg size) in Apricot/Silver.
