igure 1. (A, B) Size-frequency distribution of male Dungeness crabs captured from Coos Bay and Brookings waters (A) and corrected for catch per uniteffort at the Coos Bay site only (B). The dotted line shows the size of a legal male crab
1 - The legal size reported for harvest is 160mm in width and the sex of these harvests are male as of 2012. As of 2024, ODFW regulations show that harvests must be only a minimum of 146mm and still must only be male. Harvesters must measure this width using calipers. There is no difference for recreational or commercial dungeons crab harvesting.

Full wolf pack removal can reduce futurelivestock depredation events in a local area
Original Question - This may not be something we learn about, but why do so many people think that shooting obstacles is an option? The wolves were here before us, we took their land, why should we be killing them, we are their oppressor already.

Fig. 3. Large carnivore incidents by species and type (grizzlybear, Ursus arctos; black bear, Ursus americanus; wolf, Canislupus; and cougar, Puma concolor). Percentages are cumulativeover 1999 through 2014
2 How are the diets of wolves different from bears? How are cougars different from wolves in terms of what they eat and how they hunt? How does this knowledge inform about threats to livestock?
According to the graph in figure 3 of the paper, wolves primarily cause damage to agriculture through eating livestock while grizzly bears split between livestock eating and attractant and Black Bears primarily being attractant. Cougars and wolves both primarily cause damage through eating livestock, but wolves hunt in packs where cougars hunt alone, so wolves tend to do more costly eating of livestock all at once. Additionally cougars also tend to eat smaller animals where a wolf pack or pair will eat larger animals. This knowledge shows us that although both wolves and cougars primarily cause damage through eating livestock, and the differences in diet and choice of prey can help farmers better adapt their defenses and mitigation strategies based on the animal threat they face most often.
