Overall, trip limits were found to decrease vessel efficiency, increase high-grading, and increase discards [6]. These race for fish conditions under

traditional management led to the problems described in the remainder of this section. The time pressures and poor conservation incentives of the “race for fish” negatively affect the environment. Efforts to catch as many fish as selleck products possible in as short a period as possible led to unselective fishing practices and fleet overcapacity. Discards increased by 65% in the five years prior to catch share implementation [3], [7], [36], [37], [38], [39], [40], [41], [42], [43], [44], [45], [46], [47], [48], [49], [50], [51], [52], [53], [54], [55] and [56]. In addition, TACs were significantly exceeded (defined as exceeded by greater than 2%) 54% of the time, with the fleet landing 15% more than the TAC on average when the TAC is exceeded [3], [7], [17], [19], [27], [29], [30], [41], [42], [57], [58], [59], [60], [61], [62], [63], [64], [65], [66], [67], [68], [69], [70], [71], [72], [73], [74] and [75]. Thus, traditional approaches have difficulty sustainably harvesting fish stocks and create poor conservation incentives for fishermen, leading to high discards. The short seasons caused by the race for fish reduce fishery profitability. Per-vessel

yields declined slightly by 6%, as did per-vessel revenues [3], [17], [19], [29], [41], [48], [52], [53], [67], [68], [74], [75] and [76]. There are numerous reasons for the decline in revenues beyond decreasing Apitolisib stocks. Ex-vessel prices decreased as supply ‘gluts’ placed too much product on the market in a short period of time [personal communication].5 Furthermore, time pressure led to poor handling, declining

product quality, and more frozen fish [personal communication]. In addition, fishermen’s financial conditions declined as they redesigned their vessels to meet increasingly limited fishing constraints without landing additional fish [personal communication]. Social problems such as declining safety and unstable employment also accompanied traditional management’s negative economic and environmental impacts. Clomifene A safety index based on a combination of injuries, search and rescue missions, vessels lost, and lives lost (depending on data availability for each fishery) demonstrates that fisheries under traditional management were, on average, only 26% to 38% as safe as the same fisheries under catch shares [77], [78] and [79]. For example, search and rescue missions in Alaska halibut and sablefish fisheries rose from 25 to 33 per year in the years before catch shares [77]. At the same time, employment became unstable in many fisheries as seasons lasted only a few days or weeks.
