Overview
- Researchers analyzing footage and witness accounts concluded that Barak Tzach, 40, was killed by several dusky sharks while snorkeling off Hadera in April.
- Search teams recovered only small human remains the next day, allowing forensic identification and indicating he was consumed by multiple sharks.
- The study links the event to sharks habituated to people through public feeding, fish scraps from tour boats, and warm industrial outflows that concentrate sharks near shore.
- Authors recommend banning all artificial feeding and discouraging spearfishing to curb 'begging' behavior, warning that a shark cull would be the worst response.
- Dusky sharks are typically wary of humans and had no recorded human fatalities before this case, though bystanders captured video and reported hearing the victim's cries for help.
