Tanga Fisheries Analysis - IUCN

Although this profile is a useful one for fisheries data, there was typically a limited level of
supervision of monitors, and, equally crucial, the data management was poor to the extent that
these raw data, apart from summary profiles in Annual Reports, are no longer available to
researchers. Although an ACCESS database had been developed in 2002 under the RFIS Project
(SADC/DFID) to facilitate the entry, production analysis and reporting of data, the up-take of this
system and hence the opportunities for improved data management were limited.
4.1. First TCZCDP Fisheries Sampling Protocol (1995-2001)
With the inception of the TCZCDP there was an attempt to improve on the Fisheries Division data
collection system and to take some control over the data that was collected.
4.1.1. Description of the Sampling Method
The first protocol modified the Fisheries Division data collection form, and TCZCDP-seconded staff
collected the data. These were collected at the market place rather than at the actual landing-site.
A similar sampling protocol to that used by the Fisheries Division was employed (16-days per
month, 100% coverage of fishing trips on those days) but the data profile was adjusted and effort
was no longer recorded. The data profile is shown in Table 7.

The first village management plan was established under TCZCDP in Kigombe-Tongoni, off
Muheza District (see Table 1) and the 1 st sampling protocol was implemented at the Kigombe
landing site on the 30 th September, 1995. Further data collection activities were established at
Kipumbwi village, for the adjacent Ushongo-Sange village management plan from August 1996 to
September 1999 and at Ushongo village (Boza-Ushongo village management plan), from May to
September 1999. Figure 1 presents a short-version of the data collection form used under the 1 st
Protocol.

The database holding the 1995-2001 data has an additional category of fisheries-related data to
those collected on the form shown in Figure 1, namely size category and number of fish within
each category. There are three categories, A, B, and C (originally a fourth category was also used)
which relate respectively to the length of a hand, the length from fingertip to mid-forearm and the
length from fingertip to shoulder.
