Recreational fishing is an uncommercial activity which means hunting a full mature fish with a hooks and auxiliary tools in order to satisfy the humans need for recreation.

Restocking is a planed release of fish and fertilized eggs in the fishing  water according to the program of  fishing area management.

Statistical unit is а user of fishing area.
 

Аll users of fishing areas (35) are covered by the survey.

For information on Quality Reports see section Quality assurance.

General framework for quality assurance is defined by the Declaration on the quality or the Quality Policy, which can be accessed via the following link: http://www.stat.gov.rs/media/2334/quality-policy.pdf

Control of the data quality is carried out in all phases of survey conducting. In the preparatory phase the list of users of fishing areas is update with the evidention of Ministry of environmental protection. During the survey conducting a coverage control, control of completeness and accuracy of filled questionnaires are carried out. Further, data are controled during data entry in IST program according to the defined criteria of logical and computy control.

Quality of data can be estimated as satisfactory.

Users of these data are the Ministry of Agriculture, Forestry and Water Management, Ministry of environmental protection, Agency for environmental protection, Institute of biology, other institutions and institutes, journalists, students and other individuals.

In order to define appropriate content of the questionnaire for this survey representatives of the relevant ministries and other experts in this field were consulted to get data that would satisfy national and international needs.

As the Republic of Serbia has neither access to the sea nor fishing vessels flying its flag in the seas, and the waters of the Republic of Serbia are not a natural habitat for European eel and salmon, EU regulations relating fish catch are not relevant for the Republic of Serbia.

Data are obtained by full coverage of the reporting units. Accuracy can be assessed as medium.

Not applicable.

Reported  units on the unique list are all users of the fishing areas on the teritory of the Republic of Serbia, according to the low. Measure taken forminimising the unit non-response is follow-up interwiewing.  Brief explanation for the  filling questionnaire is given below each table in the questionnaire. In order to avoid item - non response, contact person from the SORS is assigned to contact the reporting units and provide additional explanation regarding filling in the questionnaires. In the event that, despite all the action taken, questionnaire is incorrectly filled out, this person is  obliged to make correction along with reporting unit.  There is no record on the number of these errors ie record on the number of implemented correction.

For the national purposes data are published four months after the reference period.

Conducting, processing and publishing data are done in a timely manner, according with defined deadlines.

The data are comparable at the territorial level.

Comparable and complete time series is available  from 2006.

There are no other relevant statistical data, except data on the total number of employees in the fisheries and aquaculture activity  that are the result of survey based on combining the data of the Central Registry of Compulsory Social Insurance of the Republic of Serbia and the Statistical Business Register.

Statistical data within the data set are consistent.

Funds for the production of relevant statistical data are provided from the budget of the Republic of Serbia. As this is in annual periodicity and there are small number of reporting units, the production costs of these data are insignificant. Estimated burden of reporting unit is 100 minutes per year (burden in total in the last reference year was 3500 minutes ie. 58h). There is no significant burden reduction in the last 12 months.

General policy revision was adopted by the institution, it is available on the SORS website and can be accessed via the following link:

Data revision was not applied.

Data are based on evidention and estimation of users of fishing ares and obtained by comprehensive regular statistical survey Annual report on fish catches in rivers, lakes and canals.

Data are collected on annual basis, in the period 10 February - 1 March of the current for the previous year.

Conducting of the survey Annual report on fish catches in rivers, lakes and canals is centralised.  Data are collected by reporting method, or via e-mail.

The process of data collection is envisaged to start on 10th February, when the questionnaire and the notice on the survey implementation and the deadlines are forwarded by email to the reporting units. The deadline for submitting the filled questionnaires by the reporting units is 1st March. In order to carry out additional interviews this deadline is extended until 1st April. The processing and compilation of data for the national needs shall last until the end of April. The deadline for publishing the results is 3rd May of the current year for the previous year.

Automatic and manual validation  of the dataset completness are implemented. Data validation is mostly performed on the basis of the previous year results.

Controlled data entry and data processing are done in program IST (developed by SORS). Non response of reporting units is 0%. Non response  on certain questions for key variables are solved by imputation data from the last year report of the same response unit  or from reports of other units from the current year, if it is relevant and possible. There are no items with a significant (high) non-response rate.
