LPB Frozen Shellfish Diet®

For Larva, Post-Larva & Broodstock Bivalves, Shrimp, Sea Cucumbers & More

LPB Frozen Shellfish Diet® is a highly concentrated, nutritious mix of Tetraselmis sp, Thalassiosira weissflogii and Thalassiosira pseudonana - species that have all demonstrated success with a variety of shellfish including oysters, clams, mussels, scallops, shrimp, and sea cucumbers.

These larger cells are ideal for larger larvae but are not optimal for first feeding bivalves and are recommended only after day 7 post hatch. For first feeding bivalve larvae use small cell Shellfish Diet 1800 (80% Isochrysis, Pavlova & Thalassiosira pseudonana).
