IMPORTANCE Our research group previously identified specific endogenous platinum-induced fatty acids (PIFAs) that, in picomolar quantities, activate splenic macrophages leading to resistance to chemotherapy in mouse models. Fish oil was shown to contain the PIFA 16:4(n-3) (hexadeca-4,7,10,13-tetraenoic acid) and when administered to mice neutralized chemotherapy activity. OBJECTIVE Because pa...

Abstract Northern sand lance (Ammodytes dubius) and Atlantic herring (Clupea harengus) represent the dominant lipid-rich forage fish species throughout Northeast US shelf are critical prey for numerous top predators. However, unlike herring, there is little research on or information about drivers of their abundance. We use intra-annual measurements diet, growth, condition to explain annual var...

disrupt their society and destabilise their packs. Packs may split into smaller packs made up of younger animals, with a greater influx of unrelated individuals. And younger, less-complex packs may kill cattle or approach humans for food,” Eisenberg writes. Wolves were reintroduced to Yellowstone National Park in the 1990s and are protected within its boundaries. Using the example of a pack res...

—Taurine has been demonstrated to be conditionally indispensable for several carnivorous fish species. Current trends in trout production include decreasing levels of fish-meal content in feeds, along with faster growing strains of fish. Taurine may be a limiting nutrient in support of elevated planes of growth for rainbow trout. A 9-wk feeding trial was conducted using a factorial treatment de...

C over the production of highly fecund species such as Pacific herring (Clupea pallasii) has been attributed historically to bottom-up effects such as ocean conditions or food availability. In contrast, top-down control exists when predation limits population production. Recent observations of humpback whales (Megaptera novaeangliae) foraging on depressed herring populations suggests top-down c...

Apparent digestibility coefficients (ADCs) of dry matter, crude protein, crude lipid, energy, essential amino acids, and fatty acids in extruded pellets containing various fish meals were determined for olive flounder (Paralichthys olivaceus). Eight extruded pellet diets were prepared to contain different fish meals (herring fish meal, anchovy fish meal, mackerel fish meal, sardine fish meal-A,...

During late winter, the Norwegian spring-pawning (NSS) herring migrate southward along the Norwegian coast to spawn in March-April . The larvae drif t northwards in the Norwegian coastal current during their f irst months and eventually most of the larvae and juveniles end up in the Barents Sea. Here, we have compiled measurements of temperature alon, 0 the coast back to 1936 and analyse these ...

Artificial light can change the behaviour of aquatic organisms, although the direction of response can be species and life-stage specific. Open net-pen salmon farms in British Columbia, Canada, routinely illuminate their net-pens during the winter and spring, with unknown consequences on the abundance and distribution of marine fish and invertebrates. Paired lit and control samples consisting o...
