Optimising sealed transports of small ornamental fish
Silva, Rui E.; Morais, Hugo A.; Rodrigues, Nuno V.; Reis, Tiago; Correia, João P.This paper reports on simulated long-term transports of small ornamental fish inside sealed containers. The species involved were Diplodus sargus, Gobius paganellus, Gobiusculus flavescens, Lepadogaster lepadogaster, and Lipophrys pholis. The objective of such simulations was to determine the maximum bioload that it is possible to move inside a sealed container, while ensuring 100% survivorship, ultimately resu...
New geographic distribution records for Northeastern Atlantic species from Peni...
