Modeling volume deformation in gravity-type cages with distributed bottom weights or a rigid tube-sinker

Suitability of artisanal fishery discards as feed for juvenile tub gurnard (Chelidonichthys lucerna L.) reared in sea bottom cages in the mid Adriatic Sea

“…In the current study, water quality remained stable and appeared to be sufficient to maintain fish health. To generate suitable environments for fish growth, the correct design, mooring system, hydrodynamics, and volume are required (Huang et al, 2007;Shainee et al, 2013). The present study ensured that a high concentration of dissolved oxygen was present in the fish cages because this parameter influences the growth and survival rate of cultured fish (Roncarati et al, 2013;Hwang et al, 2014).…”

Modeling the Long-Term Deformation of a Geodesic Spherical Frame Structure Made from Wood Plastic Composite Lumber

“…The reason to select these levels of stress was mentioned elsewhere [13]. The determination of E of the WPC specimens was performed in accordance with ASTM D6109 [39], by computing the slope of the line obtained from the linear regression to the linear portion in the load-midspan deflection curve. Since the span to depth ratio (L/h) of the tested WPC specimens meet the recommended L/h in the ASTM standards, the shear deformation was ignored in the computation of the apparent elastic modulus.…”

“…The investigation included a short-term (30-and 250-min) hygrothermal creep investigation, long-term (180-day) creep investigation, and the structural performance of triangular panels (components) of the aquacultural geodesic spherical rigid structure, respectively [10,11,13]. Even though numerous structural studies (static and dynamic type of analyses) were conducted on different types of aquacultural cage structures and their mooring systems [34][35][36][37][38][39][40], the time-dependent deformation of the aquacultural rigid structures has not yet been studied. Moreover, the time-dependent deformation analysis for an aquacultural structure made from viscoelastic material in general, and wood plastic composites in particular has not yet been studied [13,41].…”

An integrated approach for monitoring structural deformation of aquaculture net cages

“…The deformation of net cages in current and waves has been extensively studied by means of numerical modelling (e.g. Aarsnes et al, 1990;Lader et al, 2003;Tsukrov et al, 2003;Fredheim, 2005;Huang et al, 2007;Zhao et al, 2007;Berstad et al, 2014;Endresen et al, 2014;Moe-Føre et al, 2016;Shen, 2018) and model testing (e.g. Lader and Enerhaug, 2005;Huang et al, 2006;Kristiansen and Faltinsen, 2015).…”
