Core Event
Early Wednesday, beachgoer Michelle Greenling discovered roughly 30 small dogfish sharks washed up along a ten-block stretch of Sea Isle City, New Jersey, from 29th to 39th streets. She described the strand as “odd” and reported it to local media.
Background & Context
Dogfish (sand sharks) are common in Atlantic waters off New Jersey and often travel in large schools. In summer they move closer to shore to forage, which can lead to temporary entrapment in sandbars as tides recede. Fishermen regard them as “junk fish” because they consume bait intended for other species and frequently appear in commercial by-catch.
Data & Statistics
- Approximate number of dead sharks: nearly 30
- Length: 3–5 ft
- Weight: 8–22 lb
- Beach area: about ten blocks (29th-39th streets)
Official Statements & Responses
- Stephen Nagiewicz, marine scientist, Stockton University, said a sudden concentration of dead dogfish is unusual. He listed possible causes: a water toxin (deemed unlikely because no people were affected), accidental discarding after by-catch, or trapping on a sandbar during low tide.
- Thomas Grothues, director, Rutgers University Marine Field Station, said the pattern matches a typical commercial by-catch event, where non-target fish are unintentionally captured and later die from handling stress.
- Lawrence Hajna, media director, New Jersey DEP, noted that summer strandings are not uncommon when dogfish forage near shore and become caught in sandbars as tides go out. The DEP is not opening an investigation because the incident does not appear unusual.
Verbatim Quotes
- “A couple of things it could be. There's something in the water, and they got sick and died. That's probably unlikely since people haven't been affected,” — Stephen Nagiewicz
- “This is super consistent with a commercial bycatch of fish,” — Thomas Grothues
- “These occurrences are not uncommon in the summer when these fish forage near the shore and sometimes get caught inside sandbars as the tides goes out,” — Lawrence Hajna
Why It Matters
Understanding strandings helps fisheries managers assess the impact of by-catch on dogfish populations and informs coastal agencies about seasonal behaviors that can lead to beach strandings, reducing public alarm when similar events occur.
