A notion of positivity, called Seshadri ampleness, is introduced for a smooth curve \( C \) in a polarized smooth projective \( 3 \)-fold \( (X,A) \), whose motivation stems from some recent results concerning the gonality of space curves and the behaviour of stable bundles on \( \mathbb{P}^{3} \) under restriction to \( C \). This condition is stronger than the normality of the normal bundle and more general than \( C \) being defined by a regular section of an ample rank-\( 2 \) vector bundle. We then explore some of the properties of Seshadri-ample curves.
