Nova študija je razkrila, da delfini v Jadranskem morju vedno bolj sledijo ribiškim plovilom, da bi zbirali odpadke hrane in zavržene organizme, vedenje, ki so ga naučili od svojih staršev. Ta sprememba prehranjevalnih navad med običajnimi delfini iz steklenice poudarja naraščajočo zaskrbljenost zaradi izčrpanosti naravnega plena zaradi prekomernega ribolova.
Študija je pokazala, da na nekaterih območjih delfinom sledi kar 76 odstotkov ribolovnih čolnov, v primerjavi s samo 10 odstotki v podobnih študijah, ki so bile izvedene v devetdesetih letih prejšnjega stoletja.
Giovanni Bearzi, predsednik italijanske organizacije Dolphin Biology and Conservation in soavtor študije, je pojasnil, da se zdaj delfini pogosto nahajajo v bližini ribiških plovil, ker je naravni plen postal redek.
Čeprav to vedenje omogoča lažji dostop do hrane, prinaša tudi znatna tveganja. Delfini lahko zaradi ribolovnega orodja utrpijo poškodbe ali celo smrt, hranjenje v bližini čolnov pa lahko vpliva na njihovo prehrano, socialno strukturo in komunikacijo.
Dr. Randall Reeves, drugi avtor študije in predsednik Znanstvenega svetovalnega odbora Ameriške komisije za morske sesalce, je opozoril na možne negativne vplive tega vedenja. Poudaril je, da bi delfini lahko imeli koristi od enostavnega dostopa do hrane, dolgoročne posledice pa bi lahko škodovale njihovemu zdravju in dobrobiti. Študija je tudi poudarila, kako se mladi delfini to vedenje naučijo od svojih mater, opazujejo jih med seansi hranjenja in kulturo.
Raziskovalci so izrazili zaskrbljenost zaradi širše degradacije morskega ekosistema v Jadranskem morju in opozorili, da so običajni delfini, ki so bili nekoč številni v regiji, zdaj skoraj izumrli, razen na nekaj izoliranih območjih.
Da bi se spopadli s temi vprašanji, znanstveniki pozivajo k nujnim ukrepom za zaščito biotske raznovrstnosti in zmanjšanje vpliva uničujočih ribolovnih praks.

Index.hrNeodvisenLevovčerajA new study published in The Guardian reveals that dolphins in the Adriatic Sea are increasingly following fishing boats to scavenge discarded fish waste, a behavior learned from their parents. Scientists warn this shift is directly linked to overfishing, which has depleted natural prey and forced dolphins to adapt by relying on human activity. Researchers observed this behavior during a 148-day study tracking fishing vessels and found that the percentage of dolphins following boats rose dramatically—from 10% in the 1990s to 76% in recent years. While this adaptation helps dolphins survive in an overexploited ecosystem, experts caution that it exposes them to risks such as injury from fishing gear, disruption of social structures, and hearing damage from constant noise. The study highlights a broader ecological concern, noting that the once-abundant common dolphin population has drastically declined, leaving only small pockets of survival.
Ocena pristranskosti (Levo): The article frames the issue through the lens of environmental degradation caused by industrial fishing practices, which are often tied to economic policies and corporate interests. The emphasis on overfishing as a systemic problem, rather than a local incident, aligns with progressive environmental
tportalNeodvisenSredinavčerajScientists have observed a significant change in dolphin behavior in the Adriatic Sea, where dolphins are increasingly following fishing vessels to scavenge food scraps and discarded organisms. This behavior has become much more common compared to previous decades, with some areas showing up to 76% of fishing boats being followed by dolphins, compared to around 10% in the 1990s. Researchers warn that this behavior poses risks to dolphins, including injuries from fishing nets, changes in diet, social disruption, and potential hearing damage from boat noise. The study also notes that young dolphins learn this behavior from their mothers, suggesting a cultural transmission. Scientists highlight the broader issue of marine ecosystem degradation in the Adriatic, noting that common dolphins, once abundant, are now nearly extinct in the region. They call for reduced fishing intensity and less destructive methods to preserve biodiversity and allow fish stocks to recover.
Ocena pristranskosti (Sredina): The article presents scientific findings and expert opinions without overtly favoring any political stance. It focuses on environmental concerns related to overfishing and marine conservation, which are policy issues but are reported neutrally through research data and quotes from scientists. There
