his paper provides a comparative study of different hydrodynamic models used to predict forces on aquaculture nets. Accurate prediction of these forces is critical for ensuring fish welfare, preventing escapes, and properly dimensioning mooring systems. The review focuses on two main model types: Morison models (treating nets as collections of individual twines) and Screen models (treating nets as panels). The paper explores the strengths and weaknesses of various models within these types, considers the influence of factors like current velocity, inflow angle, solidity, and wake effects, and offers suggestions for model selection based on specific application contexts. The study also incorporates a new formula related to net-to-net wake effect, improving accuracy of simulations.
