To satisfy the Australian Government requirements for a demonstrably ecologically sustainable fishery, the fishery or fisheries if a species is caught in more than one fishery, must operate under a management regime that meets Principles 1 and 2. The management regime must take into account arrangements in other jurisdictions, and adhere to arrangements established under Australian laws and international agreements.
The management regime does not have to be a formal statutory fishery management plan as such, and may include non-statutory management arrangements or management policies and programs. The regime should:
The management regime also must comply with any relevant international or regional management regime to which Australia is a party. Compliance with the international or regional regime does not mean Australia cannot place upon the management of the Australian component of the fishery management controls that are more stringent than those required through the international or regional regime.
A fishery must be conducted in a manner that does not lead to over-fishing, or for those stocks that are over-fished, the fishery must be conducted such that there is a high degree of probability the stock(s) will recover.
Objective 1. The fishery shall be conducted at catch levels that maintain ecologically viable stock levels at an agreed point or range, with acceptable levels of probability.
1.1.3 The distribution and spatial structure of the stock(s) has been established and factored into management responses.
1.1.4 There are reliable estimates of all removals, including commercial (landings and discards), recreational and indigenous, from the fished stock. These estimates have been factored into stock assessments and target species catch levels.
1.1.5 There is a sound estimate of the potential productivity of the fished stock/s and the proportion that could be harvested.
1.1.7 There are management strategies in place capable of controlling the level of take.
1.1.8 Fishing is conducted in a manner that does
not threaten stocks of by-product species.
1.1.9 The management response, considering uncertainties in the assessment and precautionary management actions, has a high chance of achieving the objective.
Objective 2. Where the fished stock(s) are below a defined reference point, the fishery will be managed to promote recovery to ecologically viable stock levels within nominated timeframes.
1.2.2 If the stock is estimated as being at or below the biological and / or effort bottom line, management responses such as a zero targeted catch, temporary fishery closure or a 'whole of fishery' effort or quota reduction are implemented.
Fishing operations should be managed to minimise their impact on the structure, productivity, function and biological diversity of the ecosystem.
Objective 1. The fishery is conducted in a manner that does not threaten bycatch species.
2.1.4 An indicator group of bycatch species is monitored.
2.1.5 There are decision rules that trigger additional management measures when there are significant perturbations in the indicator species numbers.
2.1.6 The management response, considering uncertainties in the assessment and precautionary management actions, has a high chance of achieving the objective.
2.2.3 There is an assessment of the impact of the fishery on threatened ecological communities.
2.2.5 There are measures in place to avoid impact on threatened ecological communities.
2.2.6 The management response, considering uncertainties in the assessment and precautionary management actions, has a high chance of achieving the objective.
Objective 3. The fishery is conducted, in a manner that minimises the impact of fishing operations on the ecosystem generally.
2. Impacts on food chains
3. Impacts on the physical environment
2.3.4 There are decision rules that trigger further management responses when monitoring detects impacts on selected ecosystem indicators beyond a predetermined level, or where action is indicated by application of the precautionary approach.
2.3.5 The management response, considering uncertainties in the assessment and precautionary management actions, has a high chance of achieving the objective
The following defines how certain terms will be interpreted in application of the guidelines.
Associated and/or dependent species - species associated with or dependent upon harvested species, for example species which are predator or prey of the harvested species.
Biological diversity, biodiversity - the variability among living organisms from all sources (including marine and other aquatic ecosystems and the ecological complexes of which they are part). Includes 1) diversity within species and between species; and 2) diversity of ecosystems.
Bycatch - species that are discarded from the catch or retained for scientific purposes, and that part of the "catch" that is not landed but is killed as a result of interaction with fishing gear. This includes discards of commercially valuable species.
By-product - species that are retained because they are
commercially valuable but are
Ecologically related species - species which, while not associated with or dependent upon a harvested species, nevertheless are affected by the fishing operation.
Ecologically sustainable - use of natural resources within their capacity to sustain natural processes while maintaining the life-support systems of nature and ensuring that the benefit of the use to the present generation does not diminish the potential to meet the needs and aspirations of future generations.
Ecologically viable stock - ecological viable stock has a general rather than a specific meaning. It refers to the maintenance of the exploited population at high levels of abundance designed to maintain productivity, provide margins of safety for error and uncertainty and maintain yields over the long term in a way that conserves the stocks role and function in the ecosystem.
Ecosystem - the biotic (living) community and its abiotic (non-living) environment.
Function - relationships between components of the ecosystem, without which individuals could not survive and/or reproduce. eg protection for juveniles provided by marine plants; trophic relationships.
Management regime - In this document, refers to the
policies, plans, action plans, strategic research plans, and all documentation
that relates to the operations and management of the fishery.
Precautionary approach - used to implement the precautionary principle. In the application of the precautionary principle, public and private decisions should be guided by: 1) careful evaluation to avoid, wherever practicable, serious or irreversible damage to the environment; and 2) an assessment of the risk-weighted consequences of the various options.
Precautionary principle - the lack of full scientific certainty should not be used as a reason for postponing a measure to prevent degradation of the environment where there are threats of serious or irreversible environmental damage.
Precautionary recovery strategy - Management and operational strategy, designed to increase numbers within the stock, that incorporates the precautionary approach and includes mechanisms to avoid or mitigate adverse ecosystem effects.
Productivity - when applied to fish stocks the term productivity gives an indication of the birth, growth and death rates of a stock.
Reference point - an indicator level of fishing (or stock size) to be used as a benchmark for assessment or decision making.
Stock - In the strict sense, a distinct, reproductively isolated population. In practice, a group of individuals of a species in a defined spatial range which is regarded as having a relatively low rate of exchange with others of the species.
