Abstract: The length-weight relationship and condition factor of whiteleg shrimp Litopenaeus vannamei were described in present paper. For proposed research work the length and weight of the shrimp was measured from earthen pond of Moriraj Aqua Firm, Rohini, Khambhat taluka of Gujarat state during October 2020. The result shows that mean length, weight and condition factor were signify 11.644±0.040 cm, 18.355±0.249 gm, 1.165±0.009 for length group A, 13.466±0.025 cm, 30.510±0.233 gm, 1.246±0.006 for length group B and 14.480±0.035 cm, 38.550±0.246 gm, 1.268±0.005 for length group C while it was 13.741±0.051 cm, 32.829±0.388 gm and 1.249±0.004 for pooled population. The squire value correlation coefficient (r) depicted a strong linier relationship between the variables, it was ranged 0.674 and 0.828 for different length groups and 0.941 for pooled data. The regression coefficient or growth constant (b) was noted 3.536, 3.462, 3.239 and 3.322 for respective length groups and pooled population which is > 3.0 that indicating positive allometry growth of studied shrimp in earthen ponds.
