A passive hydrodynamic apparatus and method for harvesting marine biomass from ambient currents. The apparatus includes a non-sieving retention object comprising a porous 3D network of fibres having a fibre volume fraction (solidity) of less than 5% relative to an envelope volume defined by outer boundaries of the network inside the current. The fibres comprise surface functionalisation and have a fibre diameter of between about 1 micron and about 3000 microns, defining effective void spaces significantly larger than the target biomass particles.
