Fish and plant research in Spain-Greece for future food security

Tridge summary

The Institute of Agrifood Research and Technology (IRTA) has successfully grown glasswort, a salinity-tolerant plant, and flathead gray mullet together in an aquaponics system, as part of the EU-funded NewTechAqua project. The system was initially tested with lettuce, but 250 kg of glasswort was harvested in the second phase. Meanwhile, a study led by the Hellenic Center for Marine Research has found that the growth of greater amberjack in captivity is similar for both sexes, and that the sex ratio is 1:1, indicating that early rearing in captivity does not affect sex differentiation. The NewTechAqua project aims to diversify European aquaculture production.

The field of aquaponics has recently yielded a new plant-fish combination. For the first time, a salinity-tolerant plant commonly known as glasswort, or sea asparagus, has been grown together with flathead gray mullet (Mugil cephalus), an important food fish species found in coastal waters worldwide. The experiment was carried out by the Institute of Agrifood Research and Technology (IRTA) at its center in Sant Carles de la Ràpita, Spain, as part of the EU-funded NewTechAqua project. The system was initially tested with lettuce instead of Salicornia, as the glasswort is also known. "In January 2021, in less than three months, we harvested 90 kg of lettuce. After ensuring the system's smooth operation, in the second phase, we have already grown Salicornia, of which we ...
