Fish landing Reeords at Ports in BelgiumA deseription of methods of eolleetingstatistieal data in Belgium

by

K. Miehielsen x) and P. Hovart xx)

.~ INTRODUCTION.============

i\

In 1972 the Couneil passed the following resolution : "membercountries are urged to submit at the next meeting of the StatistiesCommittee documents deseribing the systems eurrently in use for eompilingof eateh and effort statisties from fishing vessels and the working-upof the data for submittanee to ICES on STATLANT forms, and further toinelude in the doeument speeimens of all forms used" (C. Res. 1972/4:5).

This eontribution aims at meeting the resolution of the Couneil.

1. Fish landing statisties in Belgium are designed to meet q-uitevarious requirements. On the one hand they supply thc basic data forseientifie study of the stocks and fishing effort, either in the framework of I.C.E.S. or, on a narrower national plan, in the eontext ofspecial or regional problems ; on the other hand they have to servepurposes of marketing or socio-economic politics, either 1n the framework of the E.E.C. or on national level. In this connection they areused in costs- and earnings studies.

2. All data oonccrning each landing are entered on "TABLE I" forms(Appendix Doo 1 - white form and 1a - red form).

"TABLE I" White form is civided into three seotions :Seotion I identifies the vessel (homeport, registration number, name,engine output, tonnage, registered length), desoribes thc fishing

activity (fishing method, fishing ground, statistical rectangle of± 30 miles square, number of days at sea, numbcr of days on the fishingground, number of hours at sea, number of hours actual fishing, numberof hauls) and gives port and date of landing.

Section II takes all data concerning landings of species covered bythe common market policy of the E.E.C.

The entries are for each of those specics quantity and value offish either sold on - or withdrawn from the market, both divided intoquality and size categories as they are defined by E.E.C. i Regulationnr. 2455/70 dd. 30th november 1970.

Section III takes the other spccies, grouped into bot tom fishes, pelagicfishes and crustuceans und molluscs. Again quantities und values areentered seperutely for fish sold on the market and those withdrawn whenthey did not fetch the minimum prices freely established by the producersorganisations.

In the last part of this section are entered quantities and valuesof cond~mned fish (per species).

"TABLE I" - Red form is a simplified form designed to take data concerningherring, sprut or shrimp catches, of which other spccies mentionned aresimply to be considered as by-catches.

With the exception of data concerning the fishing activity insection I, the "Table I" forms are completed by the fish-market operators,to whom is paid a small renumeration for this service.

3. Appendix Doc 2 is a form on which are entered some informationrecorded in thcir logbooks by the skippers. This form is completedby the Fisheries Inspector. The information is used to determine thenumber of days und hours at sea, thc nurnbcr of days on thc fishing ground,the number of hours actual fishing und thc statistical rcctangle whcrefishing, or the main part of it, took place.

4. Appendix Doc 3 (white fo~ the port of Ostend, yellow forZeebruges and green for Nieuport) gives daily the hour of sailingor of entering port of each fishing vessel.. These records are mainlyused to compute the length of the trip of inshore vessels, but canalso help to control the information given on Appendix Dic 2•

·- .~..'

•

5. Onee "TABLE I" form is eompleted, the information it eontainsis entered on a punch-card (Appendix Doe 4).

Those punch-cards are sent to the central statistics office inBrussels, where the information is stored on magnetic tape, to be usedto prepare national statistics and to complete Statlant forms.

The punch-cards however are sent back to the local office at Ostendwhere they are used as basic d~ta for detailed biological and eeonomicresearch work, investigations concerning productivity of fisheriestechniques etcoo. For such work the use of these cards, in combinationwitha simple equipment of a eard sorter (IBM 82), an accounting machine(IBM 424) and a small desk computer has proven to be more efficientand faster than that of large computers where programming or alterationof existing programs takes too much timeo
