What we don’t know, with the Navy planning to stage training operations in potentially contaminated waters, are the national security concerns,” Davis said. “The Navy should take a look at this and coordinate with relevant agencies to assess what can be done to prevent future spills.”Davis, a senior member of the House Armed Services Committee, may include language in this year’s defense bill to commission a Navy report regarding the cumulative tens of millions of gallons of sewage that have sickened people and forced South Bay beach closures.The 600-acre SEAL training campus is estimated to take 10 years to complete, the San Diego Union-Tribune reported. Personnel are expected to gradually migrate from the existing Naval Amphibious Base in Coronado.Davis’ call for a Navy report comes as the Port of San Diego and cities of Chula Vista and Imperial Beach forge ahead with a lawsuit alleging the federal government is violating two U.S. laws that protect water quality and public health. The suit also targets the private operator of a treatment plant that serves Tijuana.Beaches as far north as the Hotel del Coronado have been forced to close as sewage is driven out of Baja into American waters.In 2010, former U.S. Border Patrol agent Josh Willey contracted a flesh-eating bacterial infection while training at the Naval Amphibious Base in Coronado. The infection is thought to be related to sewage spills.The Mexican government announced in March it will invest $4.35 million in upgrades to Tijuana’s wastewater system to reduce sewage flows, but funds fall far short of the approximately $330 million in recommended upgrades outlined by the Baja California government.

Lett. October 2014 vol. 10 no. 10 20140643. Published 1 October 2014 DOI: 10.1098/rsbl.2014.0643AbstractThe acoustic ecology of marine fishes has traditionally focused on adults, while overlooking the early life-history stages. Here, we document the first acoustic recordings of pre-settlement stage grey snapper larvae (Lutjanus griseus). Through a combination of in situ and unprovoked laboratory recordings, we found that L. griseus larvae are acoustically active during the night, producing ‘knock’ and ‘growl’ sounds that are spectrally and temporally similar to those of adults. While the exact function and physiological mechanisms of sound production in fish larvae are unknown, we suggest that these sounds may enable snapper larvae to maintain group cohesion at night when visual cues are reduced.

But, as the research trio point out, few studies have been conducted to learn about the possibly of noise made by young fish or even fish larvae. In their study, they looked at gray snappers (Lutjanus griseus) that live off the coast of Florida.Adult female gray snappers drop their eggs in the open ocean into beds of seagrass—larvae that emerge live off food in the seagrass bed until reaching maturity. To find out if the larvae make noise, the researches put a camera, microphone and lights into a waterproof clear box and dropped it into the sea at night—the lights helped find where the snappers congregated. To make sure the noises they were recording were coming from the larvae, the researchers captured several larvae samples and took them back to their lab where they were recorded in a tank of water. Analysis of the recordings showed the larvae made two kinds of sounds: “knocking” and “growling.” Interestingly, the knocking sound was very similar to the knocking sounds made by adults of the same species. They noted also that the pattern of sounds generated by the larva differed depending on if they were in the open ocean or in the lab tank—in the lab, the larvae produced more sounds per interval and had longer times between them, suggesting perhaps that they were waiting to hear a reply.The researchers can’t say for sure why the larva make noise but suggest it might help the snappers as a whole maintain group cohesion at night when it’s more difficult to see. They suggest the growling sound may be similar to the cries that babies of many species make to get the attention of the adults. This document is subject to copyright.

Lutjanus griseus. Credit: Randall, J.E/fishbase.org (Phys.org) —A trio of researchers with the University of Miami has recorded sounds made by fish larvae in both the open ocean and in their lab. In their paper published in the journal Biology Letters, Erica Staaterman, Claire Paris and Andrew Kough describe how they captured the larvae sounds and offer ideas on why they are made.
