National Census of Maritime Artisanal Fisheries - Peru

Abstract
---------------------------

Since the 1980s, the Peruvian government has conducted significant data-collection efforts to characterize the country’s artisanal fisheries sector. In 1982, the Fisheries Ministry identified 181 disembarkment sites along the 3,000 kilometres of coastlines. The Ocean’s Institute conducted two surveys of artisanal fisheries in 1996 and 2005 to obtain information on fishing activities, socioeconomic and cultural levels, and track changes over time. Between 2002 and 2003, the Ministry of Production launched a system to collect data on the disembarkment of artisanal fishing from the coast. These studies were carried out mainly in coastal zones, an area that explains more than 90% of the landings of hydrobiological resources, which have filled a great gap in the need to characterize Peruvian artisanal fishing. However, it is still an essential need to carry out a census that allows accurate and updated data to be obtained from a population that shows high rates of variation, dispersion and mobilization.

The I National Census of Artisanal Fisheries in the Maritime Sphere 2012, was conducted in the coast of Tumbes, Piura, Lambayeque, La Libertad, Ancash, Lima, Ica, Arequipa, Moquegua, Tacna and the Constitutional Province of Callao, registering fishermen and craft shipowners at the place where they were at the time of the census, regardless of their habitual residence. The general objective of the census is to collect, process and present basic, economic, up-to-date and reliable statistical information about fishermen, shipowners, vessels, landing points and shipyards for the construction of artisanal fishing vessels on the Peruvian coast.

PROCESSING

To ensure the dissemination or reliable and timely information, data processing is centralized at INEI headquarters and processes are systemized. The process begins with the development of data entry and consistency software, digitization of information, the respective processing, and finally ensuring a consistent, coherent, reliable, and timely database is achieved.

I. Development of the Software

This step refers to preparing the necessary software for data entry, form processing, and to check the consistency of the datasets and collected in I CENPAR.
Software is also used to support other activities such as hiring of personnel, monitoring and follow-up activities and processes, document control, repository of questions and answers, and administration of look-up tables

II. Data processing

The information on the completed forms is entered manually into the database. An intelligent data entry program was designed that contemplates all the variables of the census forms.

DATA CONSISTENCY

It comprises the implementation of a set of tasks that aim to ensure that the census information collected is coherent and consistent.
The task also includes coding, which consists of assigning numerical keys or codes to the information in open questions, which allows the information to be processed electronically.
Consistency checks will be carried out by electronic means. There are a set of rules and relationships that the data collected must comply with. In the event that such relationships do not hold, the corresponding amendments to the data must be made.

GENERATION OF THE DATABASE

the information is organized in a relational model. This model allows basic information to be retrieved from the microdata at the level of the statistical units by geographic location, category of the landing point, among others.

摘要
---------------------------
自20世纪80年代以来，秘鲁政府开展了显著的数据收集工作，以描绘国家手工艺渔业部门的特征。1982年，渔业部在长达3,000公里的海岸线上确定了181个卸货点。海洋研究所于1996年和2005年对手工艺渔业进行了两次调查，以获取有关捕鱼活动、社会经济和文化水平的信息，并追踪时间上的变化。在2002年至2003年间，生产部启动了一个系统，用于收集沿海手工艺渔业卸货的数据。这些研究主要在沿海地区进行，该地区解释了超过90%的水生生物资源上岸，这极大地填补了描绘秘鲁手工艺渔业所需信息的需求。然而，仍需进行一项普查，以便从表现出高变异率、分散性和流动性的群体中获得准确且更新的数据。
2012年第一次海洋领域手工艺渔业全国普查，在图姆贝斯、皮乌拉、拉马亚克、拉利贝塔德、安卡什、利马、伊卡、阿雷基帕、莫克瓜、塔克纳以及卡亚俄宪法省的海岸线进行，记录了在普查时身处其地的渔民和手工艺船主，无论其惯常居住地。普查的总体目标是收集、处理和展示关于渔民、船主、船只、卸货点和沿海手工艺渔业船厂的基本、经济、最新和可靠的统计信息。

处理
I. 软件开发
此步骤指的是为数据输入、表单处理以及检查I CENPAR收集的数据集的一致性而准备必要的软件。
软件还用于支持其他活动，如人员招聘、监控和跟进活动及流程、文件控制、问题与答案存储库以及查找表的行政管理。
II. 数据处理
将填写完整的表格上的信息手动输入数据库。设计了一个智能数据输入程序，考虑了普查表格的所有变量。
数据一致性
包括实施一系列旨在确保普查收集的信息协调一致的任务。
该任务还包括编码，即对开放式问题中的信息分配数字键或代码，以便信息能够电子处理。
将使用电子手段进行一致性检查。收集的数据必须遵守一系列规则和关系。如果这些关系不成立，必须对数据进行相应的修改。
数据库生成
信息以关系模型组织。该模型允许从微观数据中检索基本信息，无论是在统计单位的地理位置、卸货点类别等。
