Scientists Find More Mutated Intersex Fish in Nation's Waters

All scientists have to do is search new waters, it seems, and the mystery of mutated intersex fish grows more disturbing.

Most recently, they’ve found male smallmouth bass carrying eggs in Pennsylvania’s Susquehanna, Delaware, and Ohio river basins, according to a new report by the U.S. Geological Survey. Male fish at every site sampled had immature eggs in their testes, with the highest percentage in the Susquehanna. Previously in the Chesapeake Bay drainage, research revealed evidence of the effects of endocrine-disrupting chemicals in the Potomac.

Vicki Blazer, lead author of the study, said that the pollutants affecting bass, as well as white suckers, “are most likely complex mixtures form both agriculture sources, such as animal wastes, pesticides and herbicides, and human sources from wastewater treatment plan effluent and other sewage discharges.”

"The prevalence and severity of the immature eggs in smallmouth bass corresponded with the percent of agricultural land use in the watershed above the collection sites," the scientist said. "Chemical compounds associated with estrogenic endocrine disruption, in particular estrone, a natural estrogen, were also associated with the extent and severity of these effects in bass."

Meanwhile, a toxicologist with the U.S. Environmental Protect Agency office in Denver reported that her research on fathead minnows is suggesting that “a very potent synthetic female hormone . . . can wipe out fish populations over several generations, and it’s the male fish that are most affected.”

Previously, Kristen Keteles added, studies had shown that male fish below wastewater treatment plants can lose masculine characteristics and become indistinguishable from females when exposed to estrogen and other endocrine disruptors.

“Our new study found that a potent form of female hormone estrogen used in prescription drugs not only causes the males to look female; it also appears to be toxic to male fish and these effects may impact future generations of fish.”

These disturbing discoveries regarding fish, which could portend similar problems for other species, began to emerge in the late 1970s, with anglers fishing wastewater lagoons in Great Britain, according to Whitney Jacobs, a former Conservation Associate at B.A.S.S. who researched the effects of environmental estrogens on male fish while doing graduate work in fisheries at the University of Georgia.

But the first reports of intersex was not documented in scientific literature until 1994 and the first major national assessment of the problem was not published until 2009,  she added.

“Widespread occurrence of intersex in black basses (Micropterus spp.) from U.S. rivers, 1995-2004” revealed intersex in 3 percent of fish collected and in 4 of 16 species--- largemouth bass, smallmouth bass, common carp, and channel catfish.

“However, it was most prevalent in largemouth and smallmouth bass,” Jacobs said. “The study also found the greatest incidence of the condition in the southeastern U.S.”

More recently, a 2014 report from scientists at the University of Georgia revealed these mutations aren’t confined to rivers. In “Survey of Intersex Largemouth Bass from Impoundments in Georgia USA,” they said that 48 percent of male largemouth bass collected from 11 reservoirs without direct municipal or agricultural wastewater inputs were intersex. Additionally, they found the condition in nine of the fisheries.

“The high incidence of intersex males in small impoundments demonstrates the condition is not confined to rivers and suggests that factors other than those previously associated with intersex (i.e., municipal wastewater) may be involved,” the researchers concluded.

Scientists hope that future research will reveal those additional factors. Meanwhile, they believe that fish that live downstream of wastewater treatment plants are most at risk, because of chemicals that can’t be filtered out of discharges.

“Humans excrete hormones and medications, which often end up in our rivers and streams from sewage,” said Keteles, adding that flushing medications also contributes to the problem.

“The water is treated, but many hormones and pharmaceuticals are not completely removed by wastewater treatment plants,” she said.

“My team is trying to determine what this means for fish, and ultimately for people, too.”

'I Am Haunted by Waters'

“Eventually, all things merge into one, and a river runs through it. The river was cut by the world’s great flood and runs over rocks from the basement of time. On some of the rocks are timeless raindrops. Under the rocks are the words, and some of the words are theirs. I am haunted by waters.” --- Norman Maclean

“By the time I had turned thirty, I’d realized two important things. One, I had to fish. Two, I had to work for a living.” --- Mallory Burton

Why We Fish --- Reel Wisdom From Real Fishermen

  “Even eminent chartered accountants are known, in their capacity as fishermen, blissfully to ignore differences between seven and ten inches, half a pound and two pounds, three fish and a dozen fish.” --- William Sherwood Fox, Silken Lines and Silver Hooks, 1954

“Nothing makes a fish bigger than almost being caught. ---Author unknown

“The only reason I ever played golf in the first place was so that I could afford to hunt and fish.” --- Sam Snead

Sport Fishing Advocate Retires With Warning for Anglers

Gordon Robertson, retiring vice president and lead for government affairs at American Sportfishing Association

First, I was saddened to learn that recreational fishing’s champion in Washington, D.C., was retiring, effective June 30. Then he told me something that disturbed me even more.

“The angler’s image as a conservationist needs to be rescued,” said Gordon Robertson, who officially stepped down June 30 from his post as a vice president and lead for government affairs at the American Sportfishing Association (ASA).

“Conservation once meant wise use of our natural resources,” he continued. “The word ‘conservation’ has been hijacked by the preservationist community and now policy makers don’t see anglers as conservationists.”

Instead, many politicians now view groups such as the Ocean Conservancy, the Sierra Club, and the Natural Resources Defense Council as having “conservation” agendas. Unless we reclaim what is ours through vocal activism, we will suffer loss of access and angling opportunities. As a consequence, the health of aquatic resources will suffer, because recreational fishermen are the nation’s first and foremost conservationists.

On the positive side, Robertson, who spent a dozen years at ASA, pointed out that recreational fishing continues to enjoy “an enormously positive image” among the public. We must capitalize on that, he added, “to make better habitat, more anglers, and an even stronger image.”

The West Virginia native also cautioned that we should not neglect working with the environmental community when we do share common interests on broad issues, such as water quality. “We need to strike a relationship that fosters those bigger accomplishments while gaining recognition for the role of the angler in conservation,” he said.

What I’ll remember Robertson most for was his leadership in creation of the Keep America Fishing (KAF) program in 2010. It’s now the largest angler advocacy group in the country, representing more than one million.

As KAF coordinated efforts to combat efforts to ban lead fishing tackle and restrict access, Robertson learning something that helped convince him that the image of the angler as a conservationist needs to be revitalized. “Too many anglers are apathetic and geographic,” he said.

“Some issues, like lead, resonate better than others. But collectively we need to think about the future of the sport.”

That’s just what Robertson did during his years with ASA, according to those who worked with him, including two former national conservation directors for B.A.S.S.

“Gordon Robertson has done more for anglers and sportfishing in this country than most will ever know,” said Noreen Clough. “Among other things, in his quiet but extremely effective way, he guided the last reauthorization of federal legislation that provides funding for Wallop-Breaux federal (Wildlife and Sport Fish Restoration Program), which makes significant grants to states to manage their fisheries and fishing programs.”

She added that his ability “to work effectively on Capitol Hill, even in this climate, is testimony to his political savvy and patience.”

Bruce Shupp added, “Gordon, and his predecessors, were always the first, best, and most important contact for me to get B.A.S.S. engaged in the most effective way to advocate and/or combat issues affecting the resource and industry.”

Both during his time at B.A.S.S. and as New York fisheries chief, Shupp said, “Gil Radonski, Norville Prosser, and Gordon filled the same ASA role. They were all excellent at their jobs, served the industry very well, and are among the most respected professionals I had the pleasure of working with. I hope ASA will find a similar caliber replacement.”

In that regard, ASA President and CEO Mike Nussman pointed out that Robertson “set a high bar when it came to professional excellence, which had a significant influence on everyone with whom he worked. His ability to work with Congress and federal and state agencies on complex resource issues is unparalleled.”

Fortunately for anglers, Robertson won’t step away immediately from ASA. Working a reduced schedule, he will continue to assist with on-going projects, as well as in the search for his replacement.

Whoever is selected to replacement him, however, certainly will have big boat shoes to fill.

Florida's New Regulations Help Combat Lionfish Invasion

Florida is known as a tourist-friendly state, but starting Aug. 1, one visitor will no longer be welcome: the invasive lionfish.

Introduced into Florida waters in the late 1980s, lionfish populations have boomed in recent years, negatively impacting native wildlife and habitat.

Go here to learn about the threat that they pose to native fish species.

Several management changes go into effect Aug. 1 that will help the Florida Fish and Wildlife Conservation Commission (FWC) combat the growing problem by making it easier for lionfish hunters to remove the spiny predators and limiting further introduction of the species into the waters.

Changes include:

  • Prohibiting the importation of live lionfish;
  • Allowing lionfish to be removed via spearfishing when diving with a rebreather, a device that recycles air and allows divers to remain in the water for longer periods of time (currently, you cannot spear any fish when using a rebreather); and
  • Allowing participants of approved tournaments and other organized events to spear lionfish or other invasive species in areas where spearfishing is not currently allowed (such as certain state parks or refuges). This will be done through a permitting system.

See or catch a lionfish? Report a sighting by downloading the new Report Florida Lionfish app on a smart device or by visiting MyFWC.com/Fishing and clicking on “Recreational Regulations” (under “Saltwater”) and then “Lionfish.”

Ignorance Reigns in Animal Rights Movement

PETA and other animal rights organizations that want to stop us from fishing and hunting couldn’t exist if not for financial support provided by the useful idiots who know nothing about nature and are guided purely by emotional appeals.

How stupid are they? Earlier this month, some of these mental giants viciously attacked Steven Spielberg after Jay Branscomb posted a photo with this caption on his Facebook page:

“Disgraceful photo of recreational hunter happily posing next to a Triceratops he just slaughtered. Please share so the world can name and shame this despicable man.”

By the way, triceratops, along with all other dinosaurs, have been extinct for about 65 million years. And Branscomb was having a little fun in the wake of the outrage expressed by these same people after Kendall Jones posted photos of African big game that she had shot.

But the obvious obviously wasn’t so obvious for the true believers. Here are some of the comments:

 “Steven Spielberg has absolutely no respect for animals. Posing infront [sic] of this poor dead animal like that. Barbaric.”

 “if these animals are so rare they should be moved to a reservation where it’s illegal to kill them.”

 “He’s a disgusting inhumane [bleep] Id love to see these hunters be stopped…I think zoos are the best way to keep animals safe…[bleep]holes like this piece of [bleep] are going into these beautiful animals HOME and killing them… its no different than someone coming into your home and murdering you…” 

No doubt prompted by this farce, Dan’s Papers recently posted the following:

“East End animal rights activists are up in arms about a plan to cull the dinosaur population around Georgica Pond in East Hampton. The plan under consideration, which has received support and a pledge of private funding from a certain Georgica Pond film director, involves hiring snipers with machine guns to stalk and eliminate the population of triceratops in the Georgica Pond area.

“According to area residents, the dinosaurs, which were cloned and artificially produced from prehistoric DNA and inadvertently released in a well-publicized accident several years back, have been wreaking havoc in the neighborhood: disappearances of cats, dogs, birds and even several homeowners have all been attributed to the roaming prehistoric beasts.

“Animal rights activists, who have started a group called Dinosaurs Are Friendly Too (DAFT), counter that there is no evidence that dinosaurs are to blame. “The triceratops is a beautiful, peace-loving animal that helps reduce the number of dangerous bugs in our neighborhoods,” DAFT spokesperson Reese Kriecher announced at a press conference. “Far from eating our pets, they make great pets themselves.” Authorities plan to announce a decision shortly.

 

Certainly, these people are “daft.” But they also are the same folks that PETA is counting on to assist its current campaign to stop sport fishing from piers and beaches. They might be supremely ignorant, but they have money --- and they vote.

No doubt their support was instrumental in passage of the 2001 Sasquatch Protection Ordinance in Washington State's Skamania County.
