TL;DR: Computer-based simulation provides a method to quantitatively analyze the environmental forces acting on fish cage systems and thereby provides valuable information necessary for designing an optimal structure.

TL;DR: In this paper, a physically based calculation model to simulate the flexible structures' behavior is presented in order to understand the movements and design an appropriate system, which is composed of a network of masses and springs, the behavior of which is calculated using the implicit integration method of the fundamental law of dynamics.

TL;DR: In this paper, an improved version of the numerical method used in a previous study on the dynamic simulation of purse seine gear in three dimensions is presented. The improvement is achieved by refining the mass-spring model to take into account both the drag coefficient as a function of the attack angle and Reynolds number as applied to the setting operation of the purse seiner gear.

TL;DR: A simulation tool was developed that can automatically generate a mathematical model from a gear-design drawing that was used to model the shape and movement of the fishing gear as it moved through space during the operations of shooting and pursing.

TL;DR: Investigation of the population biology and biomass of anchovy kilka Clupeonella engrauliformis in Iranian waters of the Caspian found that catches and abundance of all species have changed, but catch and sampling data are limited and stock assessments are inadequate.
