Simple and inexpensive techniques were used, to reproduce Iberochondrostoma almacai, Iberochondorostoma lusitanicum and Achondrostoma occidentale species, focusing on maintaining a realistic environment and wild behaviours. The work was built upon 10 years of research and tried to improve upon the existing conditions. Here we describe the daily maintenance protocols and the methodologies adopted to improve fish maintenance conditions and animal welfare. Fish were fed three times per week, and daily observations in fish mortality and organic build-up were performed to act accordingly. Feeding was adjusted according to weekly ammonia readings and daily measurements of dissolved oxygen, temperature and water flow. It was also observed that below 11ºC±1ºC, a complete cessation of feeding occurred in the A. occidentale stock from the Sizandro river, something particular to this population and not the species itself. The maintenance of genetically distinct populations of the same species in contiguous captive breeding tanks requires extra care, so we discuss the importance of physical barriers (due to the jumping behaviour of some species) and movement of plants/objects along with fish, to prevent the mixing of captive stocks, as well as the important role that vegetation plays as a species-specific spawning substrate, larvae refugee and protection from the elements and renewal of each population every three consecutive generations to minimize the risk of consanguinity, as key-factors for the success of the captive breeding program.
