Summer Feeding

Juvenile striped bass (age-1) of distinct genetic ancestry were re-discovered in the Saint John River, New Brunswick in 2014 after a 35 yr hiatus of recognition. These juveniles were determined to be highly genetically divergent from all possible source populations, hypothesized to be of Saint John River ancestry, and thus considered evidence of the continued existence of the native stock. Successful recruitment of strong year classes of striped bass within the Saint John River, however, appears to be infrequent. We acoustically tagged and tracked juvenile and sub-adult striped bass (n = 37; age 2-4) in the Saint John River in both 2015 and 2016, and identified summer feeding and overwintering habitats that established an in-river residency. Following decades of poor or no recruitment of the native striped bass stock, it is now imperative that managers quickly include monitoring of juvenile and sub-adult striped bass and protection of their habitats in the conservation and recovery efforts for Saint John River striped bass.

Ichthyoplankton surveys between 14 May and 15 July 1992 in the tidal fresh waters of the Northwest Miramichi River, New Brunswick, provide the first description of spawning by striped bass, Morone saxatilis, in any Gulf of St. Lawrence river. Surveys showed that striped bass spawned between late May and mid-June. Most eggs were produced in a single brief peak of abundance between 31 May and 2 June at daily average surface water temperatures of 15.6–16.6 °C. Spawning occurred largely within the first 12 km of tidal fresh water above the edge of the salt wedge. Peak spawning was centred along a 2-km stretch of river directly upriver of the salt wedge. Peak densities of larval stages were found near or upstream of the area of peak egg density. Larval densities were highest near the salt wedge.

Parasitic Burden

An unusually high mortality rate due to verminous (Philometra rubra) coelomitis was documented in wild-hatched striped bass Morone saxatilis raised in a fish hatchery as part of a stock restoration program. To decrease the parasitic burden and therefore potentially minimize mortality, the effectiveness of 2 different anthelmintics was evaluated. Two trials were conducted on wild-collected fingerlings naturally infected by P. rubra. In 2006, 144 yearling fish were randomly assigned to 4 experimental groups: (1) levamisole (Levasol®) at 2 mg l-1 via immersion for 8 h once weekly for 3 wk; (2) levamisole at a dose of 2.5 mg kg-1 biomass via feed once daily for 7 d; (3) emamectin benzoate (Slice®) at a dose of 0.05 mg kg-1 biomass via feed once daily for 7 d; and (4) control. Emamectin successfully eliminated live nematodes in 84.9% of the fish, whereas the administration of levamisole, either via immersion or feed, was not successful in significantly reducing the number of live P. rubra. In 2007, the administration of the same dosage of emamectin to approximately 1000 naturally infected yearling striped bass was associated with a 100% mortality rate of P. rubra in the 30 fish randomly examined 5 wk after the beginning of the treatment. Results of these trials indicate that, at the dosage used, the administration of emamectin at the end of the summer is safe for striped bass yearlings and considerably reduces the prevalence and intensity of the infection by this parasite.

The Relationship

This essay explores the evolving international relationship of the two national park agencies that in 1968 began to offer joint training classes for protected-area managers from around the world. Within the British settler societies that dominated nineteenth century park-making, the United States’ National Park Service (NPS) and Canada’s National Parks Branch were the most closely linked and most frequently cooperative. Contrary to campfire myths and nationalist narratives, however, the relationship was not a one-way flow of information and motivation from the US to Canada. Indeed, the latter boasted a park bureaucracy before the NPS was established. The relationship of the two nations’ park leaders in the half century leading up to 1968 demonstrates the complexity of defining the influences on park management and its diffusion from one country to another.

Into Russian Nature examines the history of the Russian national park movement. Russian biologists and geographers had been intrigued with the idea of establishing national parks before the Great October Revolution but pushed the Soviet government successfully to establish nature reserves (zapovedniki) during the USSR’s first decades. However, as the state pushed scientists to make zapovedniki more “useful” during the 1930s, some of the system’s staunchest defenders started supporting tourism in them. In the decades after World War II, the USSR experienced a tourism boom and faced a chronic shortage of tourism facilities. Also during these years, Soviet scientists took active part in Western-dominated international environmental protection organizations, where they became more familiar with national parks. In turn, they enthusiastically promoted parks for the USSR as a means to reconcile environmental protection and economic development goals, bring international respect to Soviet nature protection efforts, and help instill a love for the country’s nature and a desire to protect it in Russian/Soviet citizens. By the late 1980s, their supporters pushed transformative, and in some cases quixotic, park proposals. At the same time, national park opponents presented them as an unaffordable luxury during a time of economic struggle, especially after the USSR’s collapse. Despite unprecedented collaboration with international organizations, Russian national parks received little governmental support as they became mired in land-use conflicts with local populations. While the history of Russia’s national parks illustrates a bold attempt at reform, the state’s failure’s to support them has left Russian park supporters deeply disillusioned.
