      A growing trend of interest for the cultivation of kelp is driven by predictions for high global demands of important commodities, which require the development of alternative supplies of natural resources. In this study ...

    • Escape, discard and landing probability of Nephrops norvegicus in the Mediterranean Sea creel fishery 

      Mašanović, Marina; Herrmann, Bent; Brčić, Jure (Peer reviewed; Journal article, 2022)
      Size selection in creel fishery consists of two processes: the first taking place in the creel on the seabed and the second made by the fisher on the vessel. However, no study has ever considered both processes when assessing ...

      Commercial bycatch species and their exploitation pattern in the Mediterranean trawl fishery are little studied. The present work examines the overall size-selection pattern, both regarding the trawl in the sea and the ...

    • EspyInsideFunction.jl-extracting intermediate results from numerical functions 

      Maincon, Philippe Emmanuel (Peer reviewed; Journal article, 2022)
      EspyInsideFunction allows to write software in the Julia programming language Julia (2017) [1] to make the value of variables within a function’s local scope — variables that are neither arguments nor return values, available ...
