This presentation focuses on the technical details adopted to collect Naucrates ductor using hook & line off the central Azorean archipelago, Sphyraena barracuda using barrier nets in Horta island, Silurus glanis with barrier nets in the Ebro river and Epinephelus marginatus using traps in Horta Island. Details are additionally provided on husbandry techniques adopted for each species, with emphasis on prophilactic and post-traumatic treatments that have proved very successful over the years, such as the use of Betadine baths. Results on both simulated transports and de-facto transports are also presented, including essays conducted with the use of pH buffering and ammonia quenching agents, thus ensuring water quality remained optimal throughout transport. These essays, and subsequent transports, revealed that a formula of 25 / 100 / 100 grams of Amquel / sodium bicarbonate / sodium carbonate (respectively) yield ideal results. Additional techniques adopted for the very particular transport of a large 2,6 meter long teleost (Silurus glanis) by both road and air are also given, such as how to balance the need for degassing, while keeping a fully sealed environment, through the use of one-way valves. Further notes on the occurrence of species specific parasites on Epinephelus marginatus are also given.
