No Tritium Detected in Fish Near Fukushima Nuclear Plant

by Fishery News 27/09/2023
written by Fishery News

Fukushima, Japan – In a remarkable turn of events, authorities in Japan have reported that fish samples taken from the waters surrounding the Fukushima No. 1 nuclear plant have shown no detectable levels of tritium. This revelation comes a month after the commencement of treated radioactive water discharge into the sea, marking a significant milestone in ensuring environmental safety.

The Fisheries Agency, in collaboration with environmental authorities, has been meticulously monitoring the situation. The latest findings have left experts and the public astounded. Not a single trace of tritium was detected in two olive flounders collected on a recent Sunday. These results underscore the effectiveness of the stringent monitoring efforts aimed at dispelling any concerns about potential environmental impacts.

The treated water in question had previously been utilized for cooling melted nuclear fuel at the Fukushima No. 1 nuclear plant. Before its release into the Pacific Ocean through an underwater tunnel located 1 kilometer from the plant, it underwent an extensive treatment process to remove most radionuclides. The remaining tritium was then diluted to a mere one-fortieth of the permissible concentration under Japanese safety standards.

Fish samples collected within a 5-kilometer radius of the discharge outlet have undergone rigorous scrutiny. The latest findings add to a growing list of 64 fish samples, including flounder and six other species, all of which showed no traces of tritium since August 8. This consistent pattern reinforces confidence in the rigorous monitoring process

The transparency of these findings is evident as they are currently available in both Japanese and English. Authorities are deliberating whether to make adjustments to the frequency of updates or even provide information in additional languages, such as Chinese, to further enhance accessibility.

 

 

 

The Fisheries Agency plans to expand its investigations, aiming to examine approximately 180 samples by the end of March 2024. Importantly, the collection points are expected to remain unchanged.

This breakthrough development coincides with growing international support for Fukushima, following China’s ban on Japanese seafood imports. It indicates that there has been no significant reputational damage domestically.

This announcement reaffirms the meticulous safety measures undertaken in the aftermath of the Fukushima nuclear disaster and eliminates any lingering doubts regarding the environmental impact of treated radioactive water discharge from the Fukushima No. 1 nuclear plant. Stay tuned for further updates on this remarkable development.

written by Fishery News

Scientists from the Zoological Survey of India (ZSI) have made a remarkable discovery – a new species of vibrant orange-colored deep-water marine fish found off the coast of Digha Mohana in West Bengal.

The newly identified species, which belongs to the family Triglidae and is commonly known as gurnards or sea-robins, has been named Pterygotrigla Intermedica. It exhibits characteristics closely resembling another species, Pterygotrigla Hemisticta, according to Anil Mohapatra, a senior scientist and the leader of the discovery team from ZSI’s Estuarine Biology Regional Center in Gopalpur, Odisha.

New Species of Vibrant Orange Deep Sea Fish Discovered off West Bengal CoastThis new discovery marks the fourth species of the Pterygotrigla genus reported in India to date, with a total of 178 species in the Triglidae family worldwide.

The fish specimen was caught by a local fisherman on October 20, 2018, alongside other marine life. The research team collected a total of 24 specimens from the Digha Mohana fishing harbor during their study of by-catch components along the northern part of India’s east coast.

Upon rigorous examination, the distinctive characteristics of this fish species became evident, setting it apart from other gurnard species. Notable distinctions included snout length, the shape of the internuchal space, and the size of the cleithral spine, as pointed out by Mohapatra.

Details about this new fish species have been published in the marine science journal Thalassas on September 20, 2023.

Of the 24 collected specimens, 23 have been preserved at ZSI’s Estuarine Biology Regional Center in Gopalpur, while one specimen is housed in the Marine Fish Section in Kolkata, where further studies will be conducted.

Among the key characteristics of the new species noted by scientists are a distinct pectoral-fin with black membranes on the inner surface, a white posterior margin, and three small white spots at its base. Each ray of the fin is creamy white.

 

The species also features a unique combination of traits, such as a long opercular spine and a very short cleithral spine, a lateral line, gill rakers on the upper limb and 12–13 on the lower limb of the first gill arch, as well as a prominent black blotch located between the 4th and 6th spines of the first dorsal fin, as outlined in the research findings.

Methuselah, Beloved Australian Lungfish in San Francisco, Estimated to be 92 Years Old

by Fishery News 26/09/2023
written by Fishery News

Scientists at the California Academy of Sciences have utilized a groundbreaking DNA-based age determination method, revealing that Methuselah, the cherished Australian lungfish residing in San Francisco’s Steinhart Aquarium, is believed to be 92 years old.

This groundbreaking estimate surpasses the aquarium’s previous approximation of Methuselah’s age, which stood at 84 years. However, researchers caution that there is a nine-year margin of error, implying that Methuselah might potentially be as old as 101 years, according to a Live Science report.

Unlike conventional methods, which can be invasive and even lethal, the technique employed to assess Methuselah’s age is non-invasive and benign. It involves extracting a minuscule tissue sample from a fin clip measuring less than 0.5 centimeters.

Designated as a vulnerable species in its native habitat, the Australian lungfish holds immense importance to the Australian government. It is the last surviving member of a fish family that has endured since the era of dinosaurs, with fossil records tracing its existence back 100 million years.

This unique fish species also boasts substantial size, typically weighing around 88 pounds. Its aptly bestowed moniker, “lungfish,” is derived from its remarkable ability to respire air without relying on gills, showcasing its resilience and evolutionary significance.

Crackdown on Illegal Fishing of Juvenile Fish Intensifies off Kozhikode Coast

by Fishery News 26/09/2023
written by Fishery News

The Fisheries department’s Marine Enforcement squads have escalated their efforts to combat suspected attempts by mechanized fishing boats to catch juvenile fish in violation of Minimum Legal Size (MLS) regulations along the Kozhikode coast. Stringent measures, including intensified flash checks and harbor stock monitoring, are now in place to apprehend suspected violators.

The motive behind large-scale collection of juvenile fish appears to be driven by the demand from fertilizer factories. Reports suggest that both local and migrant fish workers engage in these illegal activities to supplement their income. Fertilizer companies located outside the state are allegedly procuring these stocks to meet their production needs.

Fisheries department officials have confirmed the impoundment of nine boats in Kozhikode as part of their concerted crackdown on all forms of illegal fishing activities. The Marine Enforcement squad boasts an adequate resource base, including patrol boats, to effectively monitor and curtail unlawful practices within the fishing industry.

In addition to hefty fines, boat registration suspension looms as a punitive measure against those engaged in illegal fishing. The department is actively seeking information from fishermen who support the strict enforcement of MLS rules and oppose the actions of fertilizer companies.

A leader from a fishermen association in Vellayil disclosed that numerous boat operators around Beypore and Puthiyappa harbors had previously collaborated in the commercial collection of inedible fish varieties for fertilizer companies. However, these operators have withdrawn from such activities as the Marine Enforcement squads have successfully impounded multiple boats. The operators had aligned with fertilizer companies due to declining revenue from daily fishing.

The Fisheries department has already compiled a list of approximately 60 fish varieties subject to MLS regulations, in line with recommendations from the Central Marine Fisheries Research Institute. Officials emphasize the critical importance of preventing the hunting of juvenile fish to preserve fisheries resources and safeguard spawning stocks.

Global Aquatic Food Production Highly Vulnerable to Environmental Change, Study Finds

by Fishery News 26/09/2023
written by Fishery News

A landmark study reveals that many of the world’s largest aquatic food producers are at high risk from human-induced environmental changes, with countries in Asia, Latin America, and Africa having the lowest adaptation capacity. Over 90% of global “blue” food production, encompassing capture fisheries and aquaculture, faces substantial risks from environmental shifts, including algal blooms, sea level rise, changing temperatures, and pesticide exposure.

Published in Nature Sustainability, the research is the first-ever global analysis of environmental stressors affecting blue food production. It ranks countries according to their exposure to these stressors. Notably, even major blue food producers like Norway, China, and the United States are vulnerable. The study highlights a lack of understanding regarding the complex interplay of stressors causing environmental change.

Key threats identified include species invasion, eutrophication, ocean warming, and sea level rise. Marine fisheries are more vulnerable to climate-related stressors, while aquaculture faces risks from diseases and low oxygen levels. Countries with high exposure and low adaptation capacity, such as Bangladesh, Eswatini, Guatemala, Honduras, and Uganda, require special attention.

The report urges transboundary collaboration, diversification of blue food production, and greater stakeholder engagement to address these challenges. Indigenous knowledge is seen as crucial in mitigating and adapting to environmental changes in artisanal fisheries and marine-dependent countries.

This study is part of the broader Blue Food Assessment (BFA) initiative aimed at informing aquatic food sustainability.

Unveiling the Unseen Impact of Artisanal Fish Fences

by Fishery News 26/09/2023
written by Fishery News

In the tranquil waters of tropical seas, where pristine marine ecosystems thrive, a seemingly innocuous fishing method has been quietly causing havoc beneath the surface. Traditional fishing gears, often referred to as artisanal fish fences, have long been used by coastal communities. These structures, constructed from wooden poles and locally sourced nets, are strategically placed in shallow waters, particularly within the intricate web of mangroves. As the tide recedes, they function like underwater labyrinths, funnelling a variety of marine species into holding structures.

For years, these artisanal fish fences were considered a sustainable alternative to industrialized fishing techniques, assumed to have a lower environmental footprint. However, a recent study published in Nature Communications has shed light on the grim reality. Contrary to previous beliefs, these unassuming fishing gears are, in fact, posing a significant threat to marine ecosystems and fisheries sustainability.

The Hidden Impact

The study, led by researchers from various institutions, including Swansea University, employed a multifaceted approach, combining ecological assessments, social analysis, and remote sensing. Over a span of more than 15 years, they meticulously examined the landings from fish fences across the Pacific, Atlantic, and Indian Oceans. The results were startling.

One of the most alarming findings was the indiscriminate nature of these artisanal fish fences. They ensnare over 500 different species, including many as juveniles and others that are of conservation concern. “Because they are unselective, they catch more than 500 species, many as babies or which are of conservation concern,” explains Richard Unsworth from Swansea University.

Furthermore, the study revealed that these traditional fishing practices have a profound impact on marine habitats. Seagrass meadows, mangroves, and coral reefs, which are the lifeblood of many coastal regions, are under siege. The fish fences disrupt vital ecological connectivity, strip away juvenile fish crucial for replenishing populations, and directly damage seagrass ecosystems. The ripple effects extend to connected coral reefs and mangroves, which suffer as a result.

Unseen Consequences

Over a decade, these traditional fishing gears have caused a staggering 50% reduction in the density of local reef fish, a fact that highlights the severity of their impact. “We find fish fences to disrupt vital ecological connectivity, exploit more than 500 species with high juvenile removal, and directly damage seagrass ecosystems with cascading impacts on connected coral reefs and mangroves,” the researchers noted in their study.

The findings emphasize the need for immediate action to address the unintended consequences of artisanal fish fences. It’s no longer a matter of merely counting fish caught; it’s about understanding the far-reaching repercussions of a single fishing technique

Charting a Sustainable Future

Dan Exton from Operation Wallacea, a conservation research organization, underscores the importance of directing management efforts toward fishing techniques that are causing the most harm. Governments, national organizations, and local communities must come together to identify solutions that support traditional practices while promoting sustainable fisheries and equitable benefits for people.

The revelation of the true impact of traditional fishing gears serves as a stark reminder that protecting our oceans and their fragile ecosystems requires a holistic approach. It’s not just about the fish we catch; it’s about how we catch them and the intricate balance of life that thrives beneath the surface. As we navigate the challenges of our changing world, preserving the wonders of our seas becomes an urgent mission for the sake of future generations and the health of our planet.
