DFO Roles and Responsibilities
This Integrated Fisheries Management plan is a five-year management plan, which covers the 2000-2004 Silverside fishery for the coastal and inland waters of Prince Edward Island.
Note: This plan is intended to operate in conjunction with an annual Silverside harvesting plan in which specific harvesting guidelines such as fishing areas, seasons, bag limits, etc. may be adjusted according to conservation requirements.
The commercial Silverside fishery on Prince Edward Island dates back to the early 1970's and is the only commercial Silverside fishery in Canada. Silversides are fished in the tidal ponds, rivers, bays and estuaries all around the Island. Trap/box net is the only authorized gear type used to fish silversides and fishers normally use dories 12 to 14 feet in length to fish these nets. The following is a brief description of a trap/box net:
Box/Trap Net: is a net set so as to enclose an area of water into which fish are guided through an opening or openings by one or more leaders. These nets are usually set perpendicular to the shoreline and as the smelt arrive at the leader they follow it and swim though the open doors into a box shaped trap. Once inside the trap, the Silversides swim in circles trying to avoid the leader and fail to locate the open doors. Fishers close the doors and remove the silversides from the box shaped enclosure.
There is 98 licenced Silverside fishers on Prince Edward Island. The majority of these fishers reside in Prince County in the Alberton and Tignish areas.
There is no aboriginal participation in the Silverside fishery and there is also no recreational fishery.
The Silverside fishery in Prince Edward Island is undertaken in the tidal ponds, rivers, bays and estuaries throughout the province. The highest concentration of fishing occurs in the Eastern part of the Island in Kings County.
The open season for Silversides is from October 1 to December 31 and the main concentration of fishing effort occurs from October 1 to mid November.

*Note that 1999 is preliminary and subject to change.
The majority of Silversides caught on Prince Edward Island are sold in a frozen state and shipped to markets in the U.S.A. There are three processing plants that freeze and ship Silversides on Prince Edward Island.
Consultations with clients are carried out in a number of ways using both formal and informal processes. The silverside fishery is covered under the Prince Edward Island Estuarine Advisory Committee. The PEI Estuarine Committee is chaired by Dept. of Fisheries and Oceans and only meets as issues come up which needs industry feed-back (at least once per year). Representation is listed below:
Prince Edward Island Estuarine Advisory Committee
- Commercial Silverside fishers
- Members of Aboriginal Communities
- Provincial Fisheries
- PEI Processors Association
- DFO Resource Management, Conservation and Protection and Science Branch
The Silverside fishery on Prince Edward Island is managed by effort controls. The most significant of these are the following;
- Limiting the number of licences
- Limiting the number of nets per fisher
The Atlantic Silverside is a small schooling fish that ranges from the southern Gulf of St. Lawrence to Florida. Silversides spawn in the early summer and fish from each summer's spawning form the bulk of the catch in the following fall. The life cycle is brief and only a very small proportion of silversides reach the age of two years. The species is encountered mostly near shorelines, especially in estuaries and coastal ponds, but it may also undergo offshore migrations in winter.
Silversides are consumed by a wide variety of predators, including birds, seals, and groundfish. Seals commonly prey on silversides near or in traps, which affects commercial catches. Silversides frequently school with three-spined sticklebacks (pinfish), and undesired stickleback bycatch may make Silversides catches un-sellable.
Silversides are not subject to formal scientific assessment. Because of the species' short life cycle, stock size fluctuates greatly among years. Landings are taken as a reflection of stock status, although landings are also influenced by market demand.
No research on Silversides is presently being conducted, nor is any planned.
Silverside landings, presumed to reflect stock size, have fluctuated with no overall trend since the 1970s. It is presumed that they will continue to do so. Available biological data on PEI Silversides are presented in:
Cairns, D.K. 1996. An update on the Atlantic Silverside fishery of Prince Edward Island, 1995. DFO Atl. Fish. Res. Doc. 96/116. 9 pp.
Cairns, D.K. 1997. A biological review of commercial diadromous fishes of Prince Edward Island. Can. Stock Assess. Sec. Res. Doc. 97/74. 53 pp.
Long term objectives for the Prince Edward Island silverside fishery include the following:
- To ensure the conservation of Silverside stocks;
- To ensure basic needs of aboriginal peoples for food, social and ceremonial purposes are met as a priority after conservation requirements through the development of AFS agreements;
- Match fishing effort with available resources in the commercial fishery;
- Improve scientific information base on Silversides;
- Improve statistical data collection on Silverside landings and fishing effort.
The management objectives for the smelt fisheries in Prince Edward Island are as follows:
- To promote and ensure the conservation and protection of Silversides and their habitat;
- To ensure optimal use by commercial interests both now and for the future generations;
- To improve data collection on fishing effort and landings.
There are no international considerations with respect to the management of Silverside stocks in the Prince Edward Island area, as they do not migrate outside of our local coastal region.
- Aboriginal Fishery
To work together to ensure that aboriginal communities have first access to the Silverside fishery after conservation requirements are met. Prince Edward Island hosts two Aboriginal First Nations; Lennox Island First Nation on Lennox Island and Abegweit First Nation located in Rocky Point, Scotchfort and Morell Rear and one Aboriginal umbrella organization the Native Council of PEI located in Charlottetown.
- Recreational Fishery
There is no recreational Silverside fishery on Prince Edward Island.
The following are the objectives for commercial fisheries:
- To optimize the use of a limited resource while achieving profitability and sustainability;
- Ensure fishing effort is evenly distributed;
- Maintain the cap on the number of licences and reduce through attrition;
- Improve data collection on fishing effort and landings throughout the area.
There is no exploratory/experimental Silverside fishery on Prince Edward Island.
Issue: Aboriginal Access to the Commercial Fishery The aboriginal community does not have any commercial Silverside licences.
Utilize existing programs under the Aboriginal Fisheries Strategy to obtain commercial licences for the aboriginal community.
Issue: Berths for Silverside Trap/box Nets
Fishers in the Eastern part of Prince Edward Island have traditionally been assigned berths for their Silverside nets while fishers in the Western part of Prince Edward Island have operated on a first come basis for net berths. This causes gear conflict issues when fishers from the Western part of the province decide to fish in the Eastern part of the province in areas where berths have already been assigned.
Develop a uniform approach to berths for the entire province by meeting with fishers and Conservation and Protection personnel to decide if a total berthage system or a first come, first serve access to berths would be the best approach.
The fishing season for Silversides using trap/box nets is from October 1 to December 31.
This fishery is controlled and monitored by fishery officers in vehicles, small launches, ATV's and on foot patrols. Fishing gear and licences are checked to ensure that only licensed fishers partake in the fishery.
There is no quota assigned to the Silverside fishery as it is managed by effort controls (i.e. season, #of licences, etc.)
All individuals participating in the Silverside fishery must be registered as commercial fishers. Silverside fishing licences must be renewed on an annual basis. Fishers can combine licences up to the maximum allowable amount per gear type. The maximum amount for trap/box nets is 2 nets.
Fisheries Act, Fishery (General) Regulations, Maritime Provinces Fishery Regulations and the Aboriginal Communal Fishing Licences Regulations.
Conservation and Protection are tasked with ensuring compliance of numerous Silverside fishers in a commercial fishery on Prince Edward Island.
The commercial fishery is limited to trap/box nets set in tidal waters.
Market conditions seem to dictate activity in this fishery.
The main activity in this fishery involves fishery officers conducting patrols on land and at sea to monitor license compliance, seasonal closures, and other regulatory compliance's, such as net distances, channel obstruction, and net identification.
Fishery Officers conduct patrols using small launches, ATV's, motor vehicles and on foot to ensure compliance of above activities.
No directed flights dedicated to Silverside fishery but any opportunity to monitor this fishery in conjunction with other directed flights is an asset.

Atlantic silverside (Menidia menidia)
Common names: silverside, capelin.
- The Atlantic silverside is found along the Atlantic coast from Florida to the southern Gulf of St. Lawrence. Its habitat includes river estuaries, barachois ponds, and open salt water.
1.2 Physical Characteristics
- The Atlantic silverside is a small shiny fish with a silver stripe running along its flanks.
- Silverside is smaller than capelin, which only occasionally occur in the southern Gulf of St. Lawrence. The silverside's habit of forming dense schools in shallow water may be the reason that some erroneously call it "capelin."
- Silversides in the fall of their first year of life measure about 9.5 - 10 cm fork lengths. Silversides in the fall of their second year of life measure about 10 - 10.5 cm fork length.
1.3 Facts on silversides
- Silversides have the shortest lifespan of any commercial fish species on PEI.
- The great majority of silversides taken in the commercial fishery are only about five months old.
1.4 Fishing Facts
- Silversides are commonly used as food for exotic birds in zoos.
- Prince Edward Island is the only province in Canada where there is a commercial silverside fishery.
- PEI accounts for two thirds of the world landings of silversides.
- Silverside catches often include sticklebacks (pinfish), which are not acceptable in the marketplace. The presence of stickleback bycatch has a dampening effect on silverside fishing effort.
- The silverside fishery on PEI is concentrated in the eastern end of the province, where the modern commercial fishery began in the 1970s.
1.5 Natural History
- Silversides enter estuaries, marshes, and creeks in spring to spawn. In PEI, spawning occurs in June.
- Eggs are about 1 mm in diameter. They stick to vegetation for about 10 days, whereupon they hatch.
- At least in southern areas, determination of sex is influenced by water temperature. Silversides thus differ from most other fish, whose sex is determined by genetics.
- Because they are small and locally abundant, silversides are a food source for many species of fish, birds, and marine mammals.
