<br />TIle "dealer" would be dclined .1S () firm or person whose
<br />income derives {rom live .ornamental aquarium fIShes.
<br />~. Urge that the importation ol fishes lor purposes of
<br />research nOI involving introduction inlaa n3turalecosystcm. or
<br />(or display in public aquaria by individuals or organizations. be
<br />made under agreement with responsible government agencies.
<br />Such importers will be subject 10 investigatory procedures
<br />currently existing and/or to be developed, and species so
<br />imported shall be kept under condilions_pr.~ting esca~ or
<br />accidental introduction. Aquarium hobbyists should be en.
<br />couraged to purcha:;e rare ornamental fIShes through such
<br />importers. No fIShes shall be released into any natural ecosys.
<br />tern upon termination of research or display.
<br />5. Urge that all species considered lor release be prohibited
<br />and considered undesirable (or any purposes of introduction
<br />into any ecosystem unless that species shall have been evalu-
<br />ated upon the lollowing bases and lound to be desirable:
<br />a. RATIONALE. Reasons for seeking an import should be
<br />clearly stated and demonstrated. It should be clearly noted
<br />what qualities are sought that would make the import more
<br />desirable than native (arms.
<br />b. SEARCH. Within the qualifICations set forth under RA 11.
<br />ONAlE, a search of {X>SSlble contenders should be made,
<br />with a list prepared of those that appear most likely to
<br />succeed, and the lavorable and unfavorable aspects of
<br />each species noted.
<br />c. PREUMINARY ASSESSMENT OF THE IMPACT. This
<br />should go beyond the area of RA 110NAlE to consider
<br />impact on larget aQualic ecosystems, general e((ect on
<br />game and (ood fishes or walerfowl, on aQualic plants and
<br />public health. The published information on the species
<br />should be reviewed and the speci~s :;hould be studied in
<br />preli:1'\:r.ary fashion ~n it$ bimope.
<br />d. PUBLICiTY AND REVIEW. The subject shauld be en.
<br />tirel}' open and expert advice should be sought I: is althis
<br />pain:. that thoroughness is In order. No imporlotlon is so
<br />urgent that it should not be ~ub;ect to !:areful evaluation.
<br />e. EXPERIMENTAL RESEARCH. If a prospective impact
<br />passes the rirst lour steps. a research program ~hould be
<br />initiated by an appropriate agency or organization 10 lest
<br />the import in cO!lfined waters (ex.perimcnial ponds. elc.)
<br />I. EVALUA liON OR RECOMMENDA TION. Again pubJ;c.
<br />it>' is in order and complele reports -should be circulated
<br />~mon9st lnteresled !.cientists ~nd presented for pub.
<br />lic,)tion.
<br />g. INTRODUCTION. \Alilh favorable evaluation, the reo
<br />leases should be effected and monitored, 'AAth results pub.
<br />lished or circulaled.
<br />Because animals do nOt respect pol1l1cal boundaries, il wouid
<br />seem thai an international. national. and regional agency should
<br />be involved at the starl and have Ihe veto power at the end.
<br />Under this procedure there is no doubl (hat fewer introductions
<br />would b:e accomplished, but Quality and. not Quantity is desirp:d
<br />and many mistakes might be aVOIded.
<br />
<br />B. The SOCiely encourages inlCfndtional. national, and reo
<br />gional nalural re~ource agencies 10 endorse and follow the
<br />intent of 1 he above position.
<br />C. The Sociefy encourages IOternallona! .harmonlzation of
<br />guidelines. protocols, codes or praCl1ce. etc.. as they apply to
<br />inlrodUCllon of 3Qualic specIes
<br />
<br />O. Fishcries professionals and olher aQu3lic specialists are
<br />urged 10 become more aware of issues relating 10 introduced
<br />species.
