How to build a sustainable seaweed industry is important in Europe’s quest to produce 8 million tons of seaweed by 2030. Based on interviews with industry representatives and an expert-workshop, we developed an interdisciplinary roadmap that addresses sustainable development holistically. We argue that sustainable practices must leverage synergies with existing industries (e.g. IMTA systems, offshore wind farms), as the industry develops beyond experimental cultivation towards economic viability.

Aim: This study sets out to understand the variability in larval traits of dispersive life stages of a famous invader, the European shore crab Carcinus maenas, in its native distribution range. Location: North East Atlantic coast from the Norwegian Arctic to the southern European distribution limit of C. maenas in Southern Spain. Taxon: European shore crab Carcinus maenas (Crustacea, Decapoda). Methods: We quantified latitudinal patterns in larval body mass, elemental composition (C and N content), and thermal tolerance of the first larval stage. We collected crabs from four populations spanning 25° of latitude (Vigo in Northern Spain; Bergen, Trondheim, and Bodø in Norway) and reanalysed published and unpublished data of body mass and elemental composition of additional populations from Germany, Wales, France, and Southern Spain. Furthermore, we used two laboratory experiments to test the thermal tolerance limits of the first larval stage from Vigo and the Norwegian populations. In the first experiment, we reared larvae from hatching to Zoea II at seven temperatures (9°C–27°C) and from hatching to LT50 at 6°C. In the second experiment, we exposed freshly hatched larvae acutely to increasing or decreasing temperatures (up to 40°C and down to 3°C). Results: Across the entire European range, we found a substantial increase in dry mass and carbon and nitrogen content of freshly hatched larvae with latitude. Norwegian populations exhibited higher survival at 9°C than the Vigo population. Furthermore, LT50 at 6°C increased from South to North. All populations showed high survival in the range 12°C–24°C but low survival at 27°C.

European fruit research institute network (EUFRIN) has started coordinated apple rootstock trials across the Europe in 2017. Until now, nineteen research institutions from 14 countries established 6 apple rootstock trials where 33 apple rootstocks of different vigour are in tests. Introduction of new apple orchard designs, multileader canopies usually require more vigorous rootstocks. Investigations of semi-dwarfing apple rootstocks ‘PFR1’ and ‘PFR3’ (New Zealand), ‘G.935’ and ‘G.202’ (US), ‘EM_01’ (UK) and ‘G.11’ as control were performed with apple ‘Galaval’ in Spain, France, and Lithuania during 2017-2023. On the average of five trial sites, the most vigorous trees were on ‘EM_01’, ‘PFR1’ and ‘PFR3’, exceeding vigour of trees on ‘G.11’ by 61 – 84%. Apple trees on rootstocks ‘PFR1’, ‘PFR3’ and ‘G.935’ produced higher cumulative yields, ‘G.202’ similar and ‘EM_01’ significantly lower yield comparing with ‘G.11’. Fertility index of ‘G.935’ equalled fertility of dwarfing ‘G.11’. Fertility index of ‘PFR3’ was similar to ‘G.202’, and the lowest was recorded for ‘EM_01’. Average fruit size did not depend on rootstocks. Rootstock – site interaction was not significant for tree vigour, fruit size, however significant interactions were recorded for cumulative yield and fertility index.

European fruit research institute network (EUFRIN) has started coordinated apple and pear rootstock trials across the Europe in 2017. First pear rootstock trial was established in 2019 where quince rootstocks from NIAB (UK) breeding program ‘QR196-9’ and ‘QR530-11’ were compared with rootstocks ‘Adams’ and ‘Sydo’. Investigations were conducted with pear cultivar ‘Conference’ in Spain, Romania, Poland and Norway during 2019-2023. In all sites the most vigorous pear trees grew on ‘QR196-9’ rootstock. On the average of four trial sites, the weakest growth was recorded on ‘QR530-11’, except the Spanish site. Pear trees on rootstock ‘Adams’ produced the highest cumulative yields. Cumulative yields on other rootstocks were significantly lower by 16-23% without significant differences between them. However, site geographical position, climate and soil properties had a significant effect on rootstock performance. Similar to trees on ‘Adams’ high pear yield in Spain was harvested from trees on ‘QR196-9’; on ‘QR530-11’ rootstock in Poland, but ‘Sydo’ and ‘QR530-11’ rootstocks gave the highest yield in Romania. On the average of all sites, the least cumulative fertility index was recorded on ‘QR196-9’. Significant rootstock site interactions were revealed: rootstock ‘Adams’ had the highest cumulative fertility index in Spain and Norway, while rootstock ‘QR530-11’ in Poland and Romania.
