Fisheries

Within FishSource, the term "fishery" is used to indicate each unique combination of a flag country with a fishing gear, operating within a particular management unit, upon a resource. That resource may have a known biological stock structure and/or may be assessed at another level for practical or jurisdictional reasons. A fishery is the finest scale of resolution captured in FishSource profiles, as it is generally the scale at which sustainability can most fairly and practically be evaluated.

MANAGEMENT QUALITY

As calculated for 2012 data.

The score is 7.0.

There is an escapement goal with a lower bound of one million sockeye salmon currently in place for passage by a counting weir placed 5km downstream from Kuril Lake. The goal was established on the basis of stock-recruit data, and was established in 1994, lowering the previous goal (which was in place in 1970-1994) by 1.5 million fish. Although the goal has not been lowered in the recent past (i.e. the last 10 years), the magnitude of the 1994 lowering places into question whether or not the current goal is representative of Smsy. Furthermore, the escapement goal may not protect all sub-components of the Ozernaya sockeye stock, and fishing pressure is sometimes weighted unevenly to the beginning or to the end of the spawning run. This was reflected in the MSC assessment report for the fishery, in which a score of "70" was given for relevant performance indicator 1.1.2 (Reference points). A relevant draft condition (#1) of the fishery's certificate requires the fishery to demonstrate the suitability of the target reference points for maintaining the productivity and diversity of the stock (MRAG 2012). The fishery receives a "7" under the FishSource methodology because publicly available, verifiable information suggests that sub-stock diversity is not adequately accounted for by the escapement goal currently in place.

Management Responsiveness Subscores

As calculated for 2012 data.

The score is 10.0.

Fishery closures have been employed in the recent past when escapement was low (Bugaev et al. 2009). Recently, "pass-days" (temporal fishery closures), which were applied only to the in-river fishery in the past, were also applied to the coastal trap nets as well (a four-day closure was applied in 2010) (MRAG 2012). This is reflected in the MSC assessment report for the fishery, which rated relevant performance indicators 1.2.1 (Harvest strategy) and 1.2.2 (Harvest control rules and tools) "95" and "90," respectively. "The harvest strategy is responsive to the state of the wild stock and is designed to achieve stock management objectives reflected in wild escapement goals" (MRAG 2012).

As calculated for 2012 data.

The score is 10.0.

There are no depleted stocks that require management recovery actions.

Adequacy of Data Subscores

As calculated for 2012 data.

The score is 6.0.

Illegal, unreported and undocumented (IUU) fishing is a threat to the sustainability of salmon fisheries in Russia, and is a particularly acute problem on Kamchatka. The upper part of the Ozernaya River system is located in the Yuzhno-Kamchatskiy Federal Sanctuary, which has implemented strong anti-poaching enforcement policies since 2007 (World Wildlife Fund Russia 2010). In the lower part of the river, fishing companies have organized independent anti-poaching efforts. However, the fishery received a score of "75" on relevant performance indicator 1.2.3 (Information and Monitoring) of the draft MSC assessment. According to the assessors, "illegal harvest of Ozernaya sockeye in freshwater has not been estimated for the current or historical period. All accounts suggest that illegal harvest has been reduced to low levels within the last 5 years, but illegal harvests were clearly much greater [historically] and the level of this harvest has substantial implications for interpretation of historical data on status and productivity and application to the fishery strategy." A relevant condition (#2) of the fishery's certificate requires compiling of historical data regarding illegal fishing and continuation of an independent observer program initiated in 2011 (MRAG 2012). The fishery receives a "6" for this sub-criterion in FishSource due to the current, reportedly small proportion of unquantified, illegal harvest within the Ozernaya basin.

As calculated for 2012 data.

The score is 9.0.

Besides the impact of illegal harvest in skewing current and historic harvest data, commercial harvest information is considered to be of good quality for the commercial fishing plots within and nearby the Ozernaya River, but there are questions regarding the quality of data from coastal plots located to the north of the Ozernaya and from the open-ocean driftnet fishery, which accounts for a sizable portion of the total exploitation rate on the Ozernaya stock (18% of the 87% exploitation rate in 2010-2011, expressed as an average of the two seasons) (MRAG 2012).

As calculated for 2012 data.

The score is 10.0.

Escapement monitoring here is some of the highest quality in Russia, with weir counts, sonar (recently put into place at the weir), and aerial overflights contributing to overall results (Bugaev et al. 2009).

Stock Status Subscores

As calculated for 2012 data.

The score is 10.0.

There is no evidence of stock decline in recent years in the Ozernaya River, contrary to many other areas in Kamchatka, where declines have been attributed to poaching (Dubinin 2011). In the past 15 years, the escapement goal lower bound has only been missed twice, with the misses occurring at the beginning of the time series (1997-8) rather than the end. The MSC assessment report for the fishery reflected this with its score of "90" for relevant performance indicator 1.1.1. "There is a high degree of certainty that the wild stock has been fluctuating around its target reference point" (MRAG 2012).

As calculated for 2012 data.

The score is 10.0.

Wild yield trends have increased in the past 15 years, as they also have in neighboring regions (see graphs on the Summary page of the profile).
