It can be used to obtain complete enumeration through a legal requirement. Registers are implemented when there is a need for accurate knowledge of the size and type of the fishing fleet and for closer monitoring of fishing activities to ensure compliance with fishery regulations. They may also incorporate information related to fiscal purposes e.

Data Collection Techniques

Although registers are usually implemented for purposes 6 methods of data collection than to collect data, they can be very useful in the design and implementation of a statistical system, provided that the data they contain are reliable, timely and complete 6.

Data on vessel type, size, gear type, country of origin, fish holding capacity, number of fishers and engine horsepower should be made available for the registry. Companies dealing with fisheries agencies are registered for various purposes. These companies may not only include fishing companies, but also other type of companies involved in processing and marketing fishery products.

Data, such as the number of vessels, gear type and vessel size of registered fishing companies, should be recorded during such registration. Processing companies should provide basic data on the type of processing, type of raw material, capacity of processing, and even the source of material.

Fishing vessels and fishing gears may often be required to hold a valid fishing licence. Unlike vessel registers, licences tend to be issued for access to specific fisheries over a set period of time.

Because licences may have to be periodically renewed, they can be a useful way to update information on vessel and gear characteristics. If licences must be renewed each year, data collected from licensing is particularly useful, as records are updated on an annual basis.

Registry data also contain criteria for the classification of fishing units into strata. These classifications are usually based on assumptions and a priori knowledge regarding differences on catch rates, species composition and species selectively.

In general, vessel registers are complex systems requiring well-established administrative procedures supported by effective data communications, data storage and processing components.

As such, they predominantly deal with only certain types and size of fishing units, most often belonging to industrial and semi-industrial fleets. Small-scale and subsistence fisheries involving large numbers of fishing units are often not part of a register system or, if registered, are not easily traced so as to allow validation or updating.

Questionnaires can be handed out or sent by mail and later collected or returned by stamped addressed envelope. This method can be adopted for the entire population or sampled sectors.

Questionnaires may be used to collect regular or infrequent routine data, and data for specialised studies. While the information in this section applies to questionnaires for all these uses, examples will concern only routine data, whether regular or infrequent.

Some of the data often obtained through questionnaires include demographic characteristics, fishing practices, opinions of stakeholders on fisheries issues or management, general information on fishers and household food budgets.

A questionnaire requires respondents to fill out the form themselves, and so requires a high level of literacy. Where multiple languages are common, questionnaires should be prepared using the major languages of the target group.

Quantitative and Qualitative Data collection methods

Special care needs to be taken in these cases to ensure accurate translations. In order to maximise return rates, questionnaires should be designed to be as simple and clear as possible, with targeted sections and questions. Most importantly, questionnaires should also be as short as possible.6 - 2 Introduction to Methods of Data Collection By now, it should be abundantly clear that behavioral research involves the collection of data and.

Data Collection is an important aspect of any type of research study. Inaccurate data collection can impact the results of a study and ultimately lead to invalid results.
