Fishery management
: The Ministry of Primary Industry (MPI) manages New Zealand’s fisheries by applying a variety of management measures to ensure that fishing is sustainable. The cornerstone of New Zealand’s fisheries management regime is the quota management system (QMS), which was introduced in 1986 and sets a yearly catch limit (or total allowable catch – TAC) for every fish stock. New Zealand law requires TAC limits for every fish stock to be set at levels that will ensure their long-term sustainability. The QMS manages 100 species in 638 stock areas. Other management controls imposed are closed areas, closed seasons, size limits, gear restrictions and prohibited species.
The QMS has delivered significant benefits – most of the stocks that were overfished before the introduction of the QMS now have sustainable catch limits in place. New Zealand is one of the few countries in the world that has an internationally competitive fishing industry that makes use of a natural resource on a sustainable basis.
Each year there is considerable investment in research and fisheries assessment, a significant portion of which is supported by the commercial fishing industry (2% of annual revenue). All research and assessment is reviewed by expert scientists, with participation by fisheries managers and representatives of environmental and commercial fishing interests.
The MPI invests heavily in monitoring fishing activity and in encouraging and enforcing compliance with the law. Fishery Officers patrol New Zealand’s coastline to ensure all fishers comply with the rules. In addition, Ministry Observers are periodically placed on fishing boats to monitor and record what fishers catch, and any interactions with seabirds, marine mammals or protected corals.

Stock status
: The MPI carries out regular stock assessments in collaboration with the Industry members and Universities. The latest stock assessment was published by MPI in February 2016 and it is based on data from 2015. The biomasses of all clam species fished in Cloudy Bay are well above the lower limit of the maximum constant yield.

Habitat impact:
The fleet uses hydraulic dredges and their effects on the seabed are continually monitored. A survey conducted in collaboration with the University concluded that the plume resulting from dredging completely disappears after less than thirty minutes. All the dredging activities are carried out on sand and mud seabed with no impact on kelp meadows nor nursery areas.

Discards
: The hydraulic dredge allows selecting clams over a certain size so that the discards are low. Bycatch occasionally include sole, plaice and crab but these are either landed as catch or released live at sea.

Audit Report
Corrective Actions
Vietnam – Dredge – Paphia undulata – FAO 71 (Pacific, Western Central)

Fishery client: MINH DANG CO. LTD, Soc Trang province, Vietnam.
Fishing area: FAO 71, Ba Lua Island, Kien Giang province, Vietnam.
Fishing vessels: Soc Trang fleet.
Vessels audited on site as Soc Trang fleet samples: ST-90299-TS; ST-91449-TS; ST-90848-TS; ST-90747-TS; ST-92269-TS.
Fishing method: Dredge.
Certified species: Scientific name: Paphia undulata;
Common name: Yellow clam.

Management summary
The Ministry of Agriculture and Rural Development (MARD) is the government agency that manages fisheries in Vietnam. The audited species can be caught in Vietnam in compliance with Circle No. 02/2006/TT -BTS issued by MARD and with the Official announcement No. 3397/TS – KHCN of the National Agro-Forestry-Fisheries Quality Assurance Department (NAFIQAD). There is a limited fishing season and a minimum length of 30 mm to be respected.

Stock status summary
Public data states that yellow clam is not overexploited in the fishing area. According to FAO and MARD, stock status and fishing mortality are appropriate. In addition, the audited species is not on the IUCN Red list.

Bycatch / discards
According to the logbook, there is no occurrence of discards because of the mesh size (> 40 mm), which is bigger than the minimum size of the fish to be retained.

Habitat Impact
The harvest season of yellow clam is respected, as well as the catching area established by the Sub-Department of Capture Fisheries and Resource Protection of Kien Giang province, which is 10 nautical miles from the shore on the island of Ba Lua, Kien Luong. There are no records of captured live animals.

Social Accountability performance
The fleet complies with the human rights and Vietnamese regulations.

Conclusion with reasons for approval

The fleet complies with Friend of the Sea requirements, without any major non-conformities.

Certified species: Chamelea Venus gallina
Fishing Method: Hydraulic dredge
Fishing Area: FAO 37 Black Sea, Kefken and Sile Fishing Stations
Stock Status: The sedentary often gregarious behavior of shelled molluscs is a great advantage for direct assessment approaches through trawl, dredge, or grab surveys on sandy bottom beds.
These methods are very useful to forecast the recruitment abundance into the fishery and limit the fluctuation in annual landings. This methodology, described in detail by the auditor is applied to all clams fishing areas in Turkey and assures long term sustainability and fishing within the maximum sustainable yield.
Discard: Fishing method is highly selective. Only a negligible amount of finfish is caught. Bycatch consists mainly of undersized (smaller than 17 mm) clams (30%), which are thown back to the sea), Topshell (Rapana bezoar), Black Mussels (Mytilus galloprovincialis), Golden carpet shell (Tapes aureus) and crabs, which are dropped back in the sea. This is was confirmed by auditor and by several other impact studies worldwide.
The Auditor reports from onsite inspection that maximum level of discard is 8% with average 5%ù
Habitat Impact: While the impact of hydraulic dredges on the bottom at first glance seems severe, the mechanical restrictions that the gear imposes – hose length, pumping pressure, etc. – limits their use to shallow water. The sandy bottom environments in these areas are normally exposed to far greater perturbations during winter storms and take such disturbances in stride. Consequently several dredges impact related studies indicate that the impact is small-scale and short term. The Turkish government has furthermore implemented vast protected areas, limited and strictly regulated fishing seasons and discard reduction measures.
Posidonia oceanica is spread mainly in Mediterranian and Egean coast but a small amount of Posidonia is seen in Blacksea coasts. In the north coast Egean sea, P. oceanica lives in 8m deep and in Blacksea coasts, in Sinop Cape area, P. oceanica lives between 0-6 m deep. Posidonia is a species under protection and this is determined in Turkish legislations of Ministry of Agriculture Department of Protection and Control Circular. It is known by the company that this species is under protection.
