Sarah and Andrew first met in Loveday Conquest’s QSCI 482 class. Statistics isn’t necessarily known for romance, so it’s not surprising that it wasn’t until the Fisheries Interdiscipinary Network of Students (FINS) transition meeting a couple of months later (Andrew was headed out, Sarah had just signed up) that they realized they liked each other. From that point on, Andy looked forward to class even more than usual (it was an excellent class) and thinks that his continued interest in statistics is a result. 

“How do a Japanese guy and a French girl end up in the US?” This might have been the question we were asked the most when we lived in Seattle. We actually met in grad school in France. Although Kotaro is Japanese, he grew up in Africa going to French schools. He then moved to France for higher education and that’s where we met. 

Oceanic discoveries of new species continue at pace, with a new species added to the 34,000 previously described: the Polkadot Dwarfgoby (Eviota maculosa). The new species occurs in New Guinea, Indonesia, and Pohnpei in the Federated States of Micronesia, and is distinguished by unique fin patterns, distinctive genetics, and multiple rows of trident-like teeth in both the upper and lower jaws. 

Bristol Bay in Alaska hosts one of the world’s largest salmon fisheries every year, targeting bountiful runs of sockeye salmon. The fishery is managed using escapement goals that ensure sufficient salmon escape the fishery every year to spawn upriver. Recently, increased escapement goals were proposed for Bristol Bay that were intended to allow more salmon to spawn upriver, because of calculations suggesting this would lead to larger average catches. 

Forage fish are small, densely schooling fish at the heart of many marine ecosystems. These fish, including sardines, anchovies, menhaden and their kin, consume tremendous quantities of plankton and also provide abundant food for top marine predators such as larger fish and whales. A key characteristic of these species is their dramatic fluctuation in numbers between high “bonanza” periods and low “collapse” periods, which make them hard to manage. 

Tom Quinn and colleagues have found that two decades of carcasses — nearly 600,000 pounds of fish — tossed to the left side of Hansen Creek did have a noticeable effect: White spruce trees on that side of the stream grew faster than their counterparts on the other side.

Captive breeding programs are intended to rebuild highly endangered populations, but a major problem is how to reintroduce captive-bred individuals back to their native habitat. Often, there is low survival of reintroduced individuals compared to wild-born individuals. Such is the case for the critically endangered Vancouver Island marmot, which had shrunk to just 30 individuals in 2003. A new experiment compares survival to breeding age for three strategies: transferring wild-born individuals, translocating captive-born individuals to wild habitat, and a new stepping stone strategy that involved first transplanting captive born individuals to a safe wild area with high survival before transferring them in their second year to the lower-survival final destination. 

A new study led by the University of Washington found that although dead whales are still valuable sources of fat and protein for some polar bears, this resource will likely not be enough to sustain most bear populations in the future when the Arctic becomes ice-free in summers, which is likely to occur by 2040 due to climate change. The results were published online Oct. 9 in the journal Frontiers in Ecology and the Environment.

In recent years there has been a growing debate about what proportion of the oceans is fished, with estimates ranging from well above 50% to just 4%. A new paper now looks at one of the most widespread and damaging fishing types, trawling, where a net is dragged over the sea bottom to capture fish. The new method focuses on shallower continental shelves that are less than 1000 m in depth, finding that the trawling footprint varies hugely across regions from 0.4% of the area to more than 80%, with an average of 14% for all regions examined. 

A new analysis that uses high-resolution data for 24 ocean regions in Africa, Europe, North and South America and Australasia shows that 14 percent of the overall seafloor shallower than 1,000 meters (3,280 feet) is trawled. Most trawl fishing happens in this depth range along continental shelves and slopes in the world’s oceans. The study focused on this depth range, covering an area of about 7.8 million square kilometers of ocean.
