The study examines the long-term impact of different smolt production strategies on Atlantic salmon.   Researchers investigated how varying freshwater photoperiods and diets, combined with different post-smolt rearing environments, affected mortality, growth, maturation, and the occurrence of melanized focal changes (MFC).   The findings suggest that rearing post-smolts on land might compromise fi...

This research article examines the current state of artificial intelligence (AI) within the aquaculture industry, highlighting its transformative potential and various applications.  It identifies challenges currently facing aquaculture, including disease, feed costs, and environmental concerns, and explores how AI can address these issues through monitoring, disease detection, feed optimization,...

The DNV Marine Aquaculture Forecast report provides projections for the marine aquaculture industry through 2050, examining trends in production, demand, and technology. It forecasts a substantial increase in marine aquaculture production to meet rising global food demand, driven by population growth and changing dietary preferences. The report anticipates shifts in production technologies, with i...

This research explores the impact of mooring line failures on the structural integrity of Norwegian fish farms, a critical concern as aquaculture expands into more exposed locations.  Utilizing numerical simulations with the FhSim program, the study analyzes how breakages in mooring lines affect tension distribution and buoy displacement in both single-cage and multi-cage systems under various cur...

The FAO's "Guidelines for Sustainable Aquaculture" (GSA) is a comprehensive framework to promote responsible development within the aquaculture industry. It addresses the need to balance economic growth with environmental stewardship and social responsibility. Developed through extensive consultation, the GSA provides guidance for policymakers and stakeholders to create sustainable aquaculture pra...

Xu et al.'s 2022 paper investigates the wake and turbulence properties of aquaculture nets using numerical methods.  The research compares nets constructed with twisted twines to those approximated as smooth cylinders, examining the impact of twine helixes on flow characteristics.  The study uses unsteady Reynolds-averaged Navier-Stokes (URANS) and Reynolds stress model (RSM) simulations to assess...

This document presents a numerical investigation into the wake effect on multi-cage fish farms, a critical aspect of aquaculture structure design.  The study uses the FhSim numerical program to analyze the impact of flow interactions between cages in a 4x2 array, considering factors like anchor line tension and cultivation volume.  The research compares scenarios with and without wake effects, dem...

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...

This research paper presents a new coupling algorithm for fluid-structure interaction (FSI) analysis of submerged aquaculture nets, addressing the need for precise and reliable design of novel offshore aquaculture structures. The algorithm combines two open-source numerical toolboxes: OpenFOAM (for computational fluid dynamics) and Code_Aster (for structural analysis). The core aim is to accuratel...
