The productivity of the Eastern Baltic cod (EBC) has been severely reduced over the last 25 years, for reasons that remain unclear. The size distribution of EBC has become increasingly truncated, condition and health status have deteriorated, and sexual maturation has started to occur at increasingly smaller sizes. Despite an increasing trend in recruitment during this period, reduced growth or increased mortality rates after the recruitment phase have resulted in decreasing landing levels and low profitability in the cod fishery, whereas the scientific community has difficulties in disentangling the causes of the decline of EBC. We studied changes in metabolic status in EBC between the capture years of 1995 and 2015, by investigating two aspects of fish metabolism that can be extracted retrospectively from otolith (earstone) morphometry and nitrogen content. Changes in relative otolith size to fish size are related to the metabolic history of the individual fish, and the otolith nitrogen content reveals the level of protein synthesis and feeding rate. Because otoliths accrue continuously on their surface and are biological stable (inert), the chemical content of the otolith trajectory reflects the timeline of the fish. We measured the N/Ca ratio as a proxy for protein content in EBC otolith along distal radius traverses from the core to the edge of the otolith by using secondary ion mass spectrometry (SIMS). Here we show that the otoliths have become smaller at a given fish size, and the ratio of N/Ca has increased over the studied period. These proxies reveal significant metabolic changes during the same period as the condition, and stock productivity has declined. We discuss potential mechanisms behind the metabolic changes, including elevated temperature and compensatory feeding due to nutrient deficiencies. Such changes in food quality may, in turn, relate to still unrecognized but on-going ecosystem shifts, where climate change could be the ultimate driver.

The Swedish colony St Barthélemy, established in 1785 and under Swedish rule until 1878, was an attractive island for neutral transit trade and for a large number of free people of color, many of whom became naturalized Swedish subjects. As subjects under the Swedish crown, they sought political rights through petitions, stressing their place within the colonial system. Free people of color were also connected to the Greater Caribbean and the mobility of the free port allowed for inter-colonial networks. The Swedish Governor Johan Norderling compared the activity of free people of color in the Swedish colony with other colonies, as well as Haiti and the USA. For him, free people of color throughout the Caribbean were grouped as belonging to the same community. Thus, the examples of activity in other colonies exemplified the dangers of further political rights in the Swedish colony. He also used the Caribbean network to communicate with other French, Spanish, and Dutch governors about a revolutionary plot planned by free people of color. Yet despite being nodal points within a network for planning subversive plots, St Barthélemy was not a particularly radical space in terms of independence or antislavery, but rather a space facilitating subversive actions between empires.

The small island of St Barthélemy was a Swedish colony 1784–1878 and saw its greatest population growth and trade during the turn of the nineteenth century. This was because of Gustavia, the Swedish founded free port, which attracted mariners from the Caribbean, North America and Europe. Their goal was to become Swedish subjects, as Swedish neutrality provided a benefit during the various wars at this time between France, Great Britain and the United States. As these mariners changed their national allegiance from their country of origin to Sweden, questions about their political rights emerged. The makeup, as well as the role, of the local council became a contested issue between native and naturalized Swedes. This conflict, as well as many other local and global issues, was discussed in various mediums. I have examined petitions, the newspaper The Report of Saint Bartholomew and discussions within the council, to create an understanding of how political expression was formed by the population, as well as controlled by Swedish administrators. This analysis has been performed through an intersectional framework considering gender, race and ethnicity. My study shows that while most native and naturalized Swedes believed in input from the population, they had different perceptions of what the purpose of this input was. The Swedish administration saw the political participation of the naturalized population as purely advisory, without any obligation to perform its wishes, which the population resented and protested. Gender played a significant role in the formation of political expression, as masculinity was essential to the identity of white men and free men of colour as political subjects. Yet ethnicity, in terms of place of birth, had no significant impact among the free population’s political identity, although it did render them politically unreliable in the eye of native Swedish administration.

The Swedish colony of St. Barthelemy was a meeting place in the early nineteenth century for merchants and mariners from across the Atlantic World, seeking to take advantage of Swedish neutrality. Yet not just goods, capital and people transited through the free port of Gustavia, but also information, culture and political discourse. This flow influenced the political culture of the island and its inhabitants' relation to the Swedish colonial power and their new Swedish citizenship.
