In Toyama Bay, generally known as a ‘pure fish protect,’ a small shrimp known as the ‘yokoebi’ has seen an explosive surge because the Noto Peninsula earthquake, inflicting vital injury to model fish species.
Set-net fisherman Katsuhisa Tokai commented, “These shrimp have been piling up on the nets lately, sticking to them in massive numbers.”
The yokoebi, which develop to about one centimeter, feed on fish carcasses and different detritus. Since early this yr, these shrimp have proliferated in Toyama Bay, including to the hardship of native fishermen already impacted by the earthquake.
“The nets are full of those yokoebi,” remarked a fisherman. “The fish caught within the nets are being devoured quicker than regular.”
Because the earthquake, Toyama Bay has skilled ongoing environmental disturbances. From January to Might this yr, the winter harvest of beni-zuwai crab on the Shinminato fishing cooperative dropped to round 30% of the earlier yr’s ranges.
“The crabs are seemingly buried beneath particles,” lamented a crab fisherman.
The affect isn’t restricted to crabs. The catch of shiroebi shrimp, sometimes at its peak in spring, additionally plummeted to roughly 20% of its regular ranges.
“In comparison with typical years, we’re hardly catching something,” a shiroebi fisherman famous.
Consultants recommend {that a} submarine landslide triggered by the earthquake could also be affecting fish residing close to the ocean flooring in Toyama Bay.
An official from the Toyama Prefectural Fisheries Analysis Institute defined, “Fish that stay in deeper areas could also be impacted by underwater landslides or adjustments within the seafloor surroundings, probably affecting their habitats.”
One in all Toyama’s most celebrated model fish, the “Manyo karei,” which reaches peak season from summer time via fall, can also be dealing with a historic drop in catch.
“This season, we must be catching these in massive numbers, however it’s a few tenth of the standard,” Tokai noticed.

Nonetheless, this prized model fish is scarcely showing in nets this season, with July’s catch all the way down to 1 / 4 of final yr’s. Fishing was suspended in August and solely resumed in mid-September, however not a single sole was caught. As an alternative, the nets had been stuffed with different fish, just like the madai, displaying seen injury.
Tokai pointed to a madai’s broken fin, noting, “This fin has been eaten by yokoebi.”
The injury from the yokoebi infestation has escalated, prompting fishermen to finish this season’s sole fishing prematurely.
“For the primary time, we’re not catching something from the beginning,” Tokai mentioned. “If this pattern of poor hauls continues for the following few years, the model itself might disappear.”
