To determine whether MPs are also present in the commercially important freshwater prawn Macrobrachium rosenbergii , gut, gills and muscles of farmed and wild prawns from key prawn-producing districts of southwestern Bangladesh w…

Abstract The red macroalgae Palmaria palmata is rich in protein and bioactive compounds and has been identified as a promising dietary ingredient for aquafeeds, with the potential to partially replace selected plant-based feed components. A digestibility trial and a growth trial were conducted to evaluate the potential of untreated and pretreated P. palmata as feed ingredients for juvenile Europe…

Abstract Understanding the underwater acoustic environment in Atlantic salmon ( Salmo salar ) farming is essential for evaluating potential impacts on fish welfare. This study presents a long-term characterisation of soundscapes in an open sea cage, distinguishing between baseline normal conditions, delousing and net cleaning operations. A hydrophone was deployed inside an open sea cage, with pas…

Abstract Tripneustes ventricosus (Lamarck 1816) is one of the largest and most commercially valuable sea urchins in the Caribbean. This study examined the effects of key water quality parameters on the energetic physiology of adult individuals under controlled conditions to establish the basis for their reproductive conditioning and culture. Three 30-day experiments independently assess the effec…
