Ukuvalelwa emapulazini efekthri kuveza enye yamaqiniso anzima kakhulu kwezolimo lwezilwane zezimboni. Ngaphakathi kwalezi zikhungo, izigidigidi zezilwane ziphila impilo yazo yonke ezindaweni ezinemingcele kangangokuthi ngisho nokunyakaza okuyisisekelo akunakwenzeka. Izinkomo zingaboshelwa ezitebeleni, izingulube zivalelwe emakhreyithi okumitha angemikhulu kunemizimba yazo, nezinkukhu ziphoqwe emakhejini ebhethri apakishwe izinkulungwane. Lezi zindlela zokuvalelwa zenzelwe ukusebenza kahle kanye nenzuzo, kodwa ziphuca izilwane amandla okuzibandakanya emikhubeni yemvelo—njengokuklaba, ukuzalanisa, noma ukukhulisa amaphuphu azo—ukuguqula izinto eziphilayo zibe amayunithi nje okukhiqiza.
Imiphumela yokuvalelwa okunjalo idlulela ngalé kwemingcele engokomzimba. Izilwane zibekezelela ubuhlungu obungapheli, ukuwohloka kwemisipha, nokulimala okuvela ezindaweni eziminyene nezingahlanzekile. Inani elingokwengqondo lilimaza ngokufanayo: ukungabikho kwenkululeko nokukhuthazwa kuholela ekucindezelekeni okukhulu, ulaka, kanye nokuziphatha okuphindaphindayo, okuyimpoqo. Lokhu kwenqatshwa okuhleliwe kokuzibusa kuqokomisa inkinga yokuziphatha—ukukhetha ukunethezeka kwezomnotho kunenhlalakahle yezidalwa ezizwelayo ezikwazi ukuhlupheka.
Ukubhekana nenkinga yokuvalelwa kudinga indlela exubile. Izinguquko zomthetho zokuvimbela amasistimu okuvalelwa ngokweqile, njengamakhreyithi okukhulelwa namakheji ebhethri, athole umfutho ezifundeni eziningi, okubonisa ukushintshela ezinkambisweni zobuntu. Kodwa-ke, uguquko olunengqondo luphinde luncike ekuqwashiseni komthengi kanye nokuzibophezela. Ngokwenqaba imikhiqizo etholakala ezinhlelweni ezinjalo, abantu bangaqhuba isidingo semikhuba yokuziphatha. Ngokuphonsela inselelo ukujwayela konya nokubona izakhiwo ezihlonipha kokubili izilwane kanye neplanethi, umphakathi ungathatha izinyathelo eziphusile ezibheke esikhathini esizayo lapho ububele nokusimama kungekona okuhlukile, kodwa kuyindinganiso.
Izigidi zezidalwa zasolwandle zibhajwe emjikelezweni wokuhlupheka embonini eyandayo ye-aquaciulture, lapho izimo eziningi kakhulu futhi zinganaki inhlala-kahle yazo. Njengoba ukufunwa kwasolwandle kukhula, izindleko ezifihliwe - izinkinga zokuziphatha okuhle, ukonakaliswa kwemvelo kanye nemithelela yezenhlalo - ziya ngokuya zibonakalayo. Lo mbhalo usikhanyisela ngokoqobo okunzima okubhekene nempilo yasolwandle engozini, kusuka ezindabeni zempilo yomzimba ekucindezelekeni kwengqondo, ngenkathi kufonela ushintsho olunenjongo ukudala i-aquaculture futhi eqhubekayo ye-aquaculture
