Rapidly Fishing Download

New research is shedding light on how the history of fish stocking has impacted alpine lake ecosystems in the Wind Rivers. In many cases, the genetics of trout have evolved rapidly, allowing them to survive in harsh mountain environments.

In the first few decades, people would carry milk cans full of fish on their backs or strap them to horses. In the Wind Rivers, this was largely done by one man who ran a fishing outfit in the area. Nowadays, game and fish departments across the Mountain West usually use trucks or aircraft to dump fish into lakes.

Local ecological knowledge can provide a unique source of data for conservation, especially in efforts to investigate the status of rare or possibly extinct species, but it is unlikely to remain constant over time. Loss of perspective about past ecological conditions caused by lack of communication between generations may create "shifting baseline syndrome," in which younger generations are less aware of local species diversity or abundance in the recent past. This phenomenon has been widely discussed, but has rarely been examined quantitatively. We present new evidence of shifting baselines in local perception of regional species declines and on the duration of "community memory" of extinct species on the basis of extensive interviews with fishers in communities across the middle-lower Yangtze basin. Many Yangtze species have experienced major declines in recent decades, and the Yangtze River dolphin or baiji (Lipotes vexillifer) and Yangtze paddlefish (Psephurus gladius) may have become extinct during the 21(st) century. Although informants across all age classes were strongly aware of the Yangtze ecosystem's escalating resource depletion and environmental degradation, older informants were more likely to recognize declines in two commercially important fish species, Reeves' shad (Tenualosa reevesii) and Yangtze pufferfish (Takifugu fasciatus), and to have encountered baiji and paddlefish in the past. Age was also a strong predictor of whether informants had even heard of baiji or paddlefish, with younger informants being substantially less likely to recognize either species. A marked decrease in local knowledge about the Yangtze freshwater megafauna matched the time of major population declines of these species from the 1970s onwards, and paddlefish were already unknown to over 70% of all informants below the age of 40 and to those who first started fishing after 1995. This rapid rate of cultural baseline shift suggests that once even megafaunal species cease to be encountered on a fairly regular basis, they are rapidly forgotten by local communities.

However, major challenges remain. The latest industry estimates suggest 22% of tuna stocks are experiencing overfishing and 13% are overfished. ISSF data indicates Atlantic Ocean bigeye, Indian Ocean yellowfin and Pacific bluefin tuna stocks continue to be overfished and subject to overfishing; Indian Ocean albacore and bigeye continue to be subject to overfishing but all skipjack stocks remain healthy.

The MSC recently granted awards via its Ocean Stewardship Fund that will benefit tuna fisheries long term, including 50,000 awarded to Tuna Australia and Australian Eastern Tuna and Billfish Fishery. The fishery was recertified in August 2020 and will use the funds to investigate potential sources of sustainable bait. This will help understand how factors including price, availability, target species and characteristics influence the choice of bait. Once alternate sources of bait have been identified, they will be tested on real fishing trips to check how effective they are.

The implications of this improvement are far reaching. Effective management of tuna fisheries is not only helping stocks and ecosystems to recover, but also support fishing communities and local economies. The global tuna market is worth more than US$42 billion a year and more than 6 million people are employed within the tuna industry in the Asia-Pacific region alone.

Fishing the Rapid is better at the end of May- beginning of June. I have done well starting at Middle Dam and fishing down steam. On the gazetteer it shows a campsite just down from Middle Dam. Do you know how to get to it? Rangley is where I have fished for the last 27 years. I know the area very well. Upper dam is alright, make sure you chech on the flows. Kennebago is good, start with the Rangley River and make your way up to Steep Bank pool on the Kennebago.Go up the Morton Cut-off road to the Lincon Pond Road, at the end of the MCOR you can turn right to go to Little Kennebago and pick up the Kennebago River there. Fish the river down to Big Kennebago. There is a gated road that you can walk down to the gravel bank pool. If you go left at the end of the MCOR it will take you to Aziscohos. Fish the #10 bridge and above it at Clarks Crossing. It's a snowmobile bridge. The game warden is a good guy. His name is Reggie Hammond, he also has the Kennebago River Camps up at Little Kennebago. If you stay there, you will get keys to the gate that follows the Kennebago River all the way up to Little Kennebago. I will say this about Reggie, He is strict, but fair. He very protective of the fishing in that area. I hope my info is helpful. If you need more I'm sure you can find me.

If you're going to stay at a hotel/b-n-b type place I would suggest Oquossucs Own b-n-b. Joanne Koob is the woman that runs the place and she is about the nicest woman you will ever meet! The inn is on the road behind the 4 Seasons Pub (stumbling distance after a few apres fishing cocktails:D[}: )]) and maybe 1 mile from the ramp on Rangeley AND the ramp on Mooselook. The location couldn't be any better. Trolling would be good because, if you have one of her breakfasts, you won't fit in your waders:P:P!

For every forcing scenario, particles were identically and continuously released in time from 1993 to 2012 following spatial distributions and amplitudes of significant ocean plastic sources on land (coastal population hotspots23 and major rivers24) as well as at sea (fishing26,41, aquaculture42 and shipping industries43). Source scenarios were combined using relative source contribution as well as geographical distribution presented in Supplementary Methods 4. We advected global particles in time using the forcing scenarios described above and successfully reproduced the formation of oceanic garbage patches, with the shape and gradient of particle concentrations in these areas differing amongst forcing scenarios. We computed daily particle visits over 0.2 resolution grids corresponding to our observation domain and extending from 160W to 120W in longitude and 20N to 45N in latitude. The number of daily particle visits was uniformized over the total number of particles present in the global model at a given time. The model-predicted non-dimensional concentration tag_hash_109 i of cell i, was calculated as follows:

Ocean plastic size spectrum in the GPGP. (a) Plastic mass distribution within the GPGP between size (bars) and type (colours) classes. Plastic type H include pieces of hard plastic, plastic sheet and film, type N encompasses plastic lines, ropes and fishing nets, type P are pre-production plastic pellets, and type F are pieces made of foamed plastics. Whiskers extend from lower to upper estimates per size class, accounting for uncertainties in both monitoring and modelling methods. (b) Measured mass and numerical concentrations of GPGP ocean plastics. Dots represent the mean concentrations, the whiskers and darker shades represent our confidence intervals, and the lighter shades extend from the 5th and 95th percentile of measured concentrations.

Our global model simulated the release of Lagrangian particles from significant sources of ocean plastic. It predicted that the relative contribution of marine sources (fishing, shipping and aquaculture industries) to the GPGP plastic load was above global average (Fig. 5a).

The specific characteristics of the GPGP debris suggest that only certain types of plastic have the capacity to persist at the sea surface for extended periods of time and accumulate in oceanic plastic pollution hotspots. Firstly, the vast majority of the collected GPGP objects were made of PE and PP rigid plastics and bundled fishing nets and ropes. Plastic films however, representing around 37% of PE and PP waste generation34,60, were rarely found. We hypothesize that most buoyant plastic with insufficient volume-to-surface ratios such as films may never reach the surface waters of the GPGP as they may rapidly sink to the seafloor due to biofouling58 and/or fragment into microscopic pieces that are removed from surface layers61.

Secondly, at least half of the collected GPGP plastics was composed of objects from marine based sources, while the relative source amplitudes considered in our model predicted that mass contributions from land-based plastics, even though lower than global average, would still dominate in these offshore environments. This discrepancy could be due to differences in the magnitude of certain removal processes between land-based and marine-based plastics that were not accounted for in our models. We trust that beaching is one of these processes as it may primarily remove plastics that are discarded in coastal environments through wave, tidal and onshore winds transport. Nonetheless, the GPGP dominance of marine-sourced plastics could also be attributed to their purposely engineered durability in the marine environment (e.g. strong and thick-walled nets, traps, ropes, and floats used by marine industries) as well as overestimations of land-based sources and/or underestimations of marine-based sources. In this study, we considered fishing, aquaculture and shipping to be responsible for 28.1% of the global plastic inputs into the oceans, based on coastal clean-up data62; however, observations at sea may lead to much higher estimates of plastic loads being lost or discarded at sea. As fishing, shipping and aquaculture intensify globally42, it is crucial to better quantify and mitigate this significant source of highly persistent ocean plastic. 17dc91bb1f
