Climate Change-Driven Fish Migration Poses Threat to Goa Fisheries

by Fishery News 01/10/2023
written by Fishery News

The impact of climate change on India’s east and west coasts is becoming increasingly evident as fishes, driven by changing environmental conditions, are migrating towards polar regions. This migration trend has been observed along both the east and west coasts of India, disrupting local fisheries.

Speaking at an event on the BITS Pilani KK Birla Goa campus, Sunil Kumar Singh, Director of CSIR-National Institute of Oceanography (NIO), expressed concerns about the implications for Goa’s fisheries. Singh noted that the recent increase in the catch of mackerel and other fishes in Goa was a consequence of the migration patterns shifting from the Kerala coast towards Goa due to climate change.

Singh explained, “Because of climate change, fishes are moving towards the poles, so oil sardine and other fishes are reducing along the Kerala coast and are slowly coming towards Goa. But they will move further towards the polar regions.”

Highlighting the broader impact, Singh mentioned that fish migration is a phenomenon extending across the entire Atlantic. He warned that the ‘dead zone’ along Goa’s coast, where dead fish wash ashore, is expected to increase in the coming years.

Describing a concerning annual phenomenon, Singh stated, “We have already witnessed a chaotic problem during the monsoon, with intermediate water getting into the coastal region. We observe tonnes of fishes dying in the estuary of the Mandovi near Caranzalem.” He attributed this to the reduction in deepwater formation caused by climate change, leading to lower oxygen levels and an expansion of the ‘dead zone.’

Given Goa’s heavy dependence on fisheries, Singh emphasized the potential for a chaotic situation if the trend continues. He framed the issue as a global problem with far-reaching consequences.

The Director shared his insights during the half-day Youth 20 event, part of G20 initiatives, organized by BITS Pilani Goa campus in collaboration with Goa State Biodiversity Board (GSBB) and Goa State Climate Change Cell. The discussion shed light on the urgent need for climate-conscious policies to mitigate the impact on coastal ecosystems and fisheries.

New Edible Fish Species Discovered in Odisha’s Kolab River

by Fishery News 01/10/2023
written by Fishery News

Researchers from the Central University of Odisha and the Zoological Survey of India have identified a new species of freshwater fish in the Kolab river, located in the Koraput district of Odisha. The discovery, named Garra laishrami, was made during an ichthyological survey by Supriya Surachita, a Department of Science & Technology Inspire Fellow.

Surachita’s research, conducted under the supervision of Prof. Sharat Kumar Palita, Dean of the School of Biodiversity and Conservation of Natural Resources at CUO, focuses on the diversity, distribution, and threats to fishes in the freshwater bodies of Koraput in the Eastern Ghats of Odisha.

The newly discovered cyprinid, or freshwater fish, has been named after Dr. Laishram Kosygin of ZSI, in recognition of his contributions to the study of Indian freshwater fishes. The fish category Garra is known for its elongated shape, varying in size from small to medium, and is characterized by the presence of a gular disc. Typically found in regions from Borneo to West Africa, this particular variety, Garra laishrami, is unique to the Kolab river in Odisha’s Eastern Ghats.

The fish, ranging from 76 mm to 95.5 mm in length, has an added significance – it is edible, and local communities in the region consume it. Garra laishrami is usually found beneath rocks and among stones and boulders in torrential streams and rivers.

The discovery highlights the rich biodiversity of the Kolab river, and researchers believe that a more in-depth study of Koraput is essential to uncover various types of organisms in the region. Prof. Palita expressed optimism about the possibility of finding more new fish species in the area.

Details of the study on this new fish species have been published in the taxonomy journal “Ichthyological Exploration of Freshwaters” in Germany.

written by Fishery News

The district administration in West Singhbhum, Jharkhand, is utilizing abandoned mines to generate livelihood opportunities for the youth through fish farming. The innovative move not only fosters self-reliance among the youth but also curbs the migration of the workforce to other states, addressing socio-economic challenges in the rebel-hit region.

Officials report that the initiative, launched during the COVID-19 pandemic, has proven instrumental in tackling rampant malnutrition in the area. A society of displaced individuals was formed, and fish farming, specifically using cage culture, was initiated in abandoned limestone mines at Kamarhatu and Karanjia. The endeavor, spanning 8-10 acres of land, has successfully generated income for the community, providing a sustainable source of livelihood.

District Fishery Officer Jayant Ranjan highlights the dual benefit of fish farming in these mines. It not only creates a livelihood for the local population but also contributes to addressing malnutrition concerns by providing abundant fish for consumption. Boating activities in the mines further contribute to the community’s earnings.

Ranjan expresses the administration’s commitment to expanding the initiative throughout the district, given the abundance of mines in West Singhbhum. Residents are encouraged to form societies to facilitate the implementation of fish farming in their respective areas.

Beneficiaries, mainly original landowners displaced due to mining activities, praise the initiative. Each society, comprising around 50 members, registers with the cooperative society. In one abundant mine, approximately 25 cages yield 2-3 tonnes of fish per season, with two caging seasons annually. The district administration provides comprehensive support for cage culture, enabling individuals to earn around 1.5 lakh per head per annum.

Arjun Mahapatra, a beneficiary, notes that the initiative has not only reduced migration but has also empowered local youth to become self-sufficient through fish farming. Chief Minister Hemant Soren has lauded the effort as a commendable step toward making the region’s youth self-reliant. The success of this project demonstrates the transformative impact of repurposing abandoned mines for sustainable and community-centric initiatives.

written by Fishery News

In the pursuit of maintaining healthy uric acid levels through dietary choices, health experts are often recommending the incorporation of specific Indian fish, with “Mackerel” taking the spotlight. Mackerel is lauded for its relatively low purine content, a factor associated with the development of uric acid. For individuals prone to high uric acid levels or conditions like gout, consuming fish like mackerel can aid in mitigating the risk of uric acid buildup in the body.

Here’s why mackerel, and other recommended Indian fish, make the cut for uric acid-friendly diets:

Low Purine Content: Mackerel stands out for containing fewer purines compared to certain seafood and meats. Given that high-purine foods can contribute to elevated uric acid levels, opting for lower-purine choices like mackerel is deemed beneficial.

Rich in Omega-3 Fatty Acids: Mackerel boasts an impressive profile of omega-3 fatty acids, known for their anti-inflammatory properties. As inflammation is often linked to gout, incorporating omega-3-rich foods such as mackerel may assist in alleviating the severity of gout symptoms.

Protein Source: Mackerel provides high-quality protein, serving as a valuable alternative to higher-purine red meat, which can contribute to uric acid buildup.

In addition to mackerel, other Indian fish options recommended for managing uric acid levels include:

Sardines: Another low-purine fish rich in omega-3 fatty acids, sardines are a favourable addition to a uric acid-friendly diet.

Pomfret: Widely accepted in Indian cuisine, pomfret is considered safe for those with high uric acid levels, being a lean source of protein and low in purines.

Catfish: A common freshwater fish in India, catfish is low in purines, making it a suitable choice for those monitoring their uric acid intake.

Tilapia: Although not native to India, tilapia, a readily available fish, is generally low in purines and can be easily incorporated into various dishes.

Rohu: As an Indian freshwater fish, rohu is recognized as suitable for individuals with high uric acid levels, offering essential nutrients along with protein.

Anchovies: Small, oily fish like anchovies are low in purines and high in omega-3 fatty acids, providing both flavour and health benefits.

Maintaining a balanced diet that includes a variety of foods is crucial for managing uric acid levels effectively. By integrating these fish into meals, alongside ample vegetables, whole grains, and hydration, individuals can take proactive steps in regulating uric acid levels for overall health.

written by Fishery News

Dr. Abhilaksh Likhi, Secretary of the Department of Fisheries, undertook a visit to shrimp farms in Lahli village, Rohtak, and the Regional Centre of ICAR-CIFE, Rohtak, Haryana. Engaging directly with shrimp farmers, Dr. Likhi delved into the grassroots challenges faced by those involved in saline water shrimp farming.

As part of the National Agricultural Higher Education Project (NAHEP) scheme, the Secretary distributed pedigreed common carp seed to selected farmers—an initiative pioneered by ICAR-CIFE. The move is set to bolster the aquaculture sector and enhance the quality of produce.

During discussions, Dr. Likhi underscored the imperative of converting barren land into lucrative aquafarming ventures. Scientists at ICAR-CIFE, during the visit, highlighted the extensive impact of groundwater salinization in inland states, affecting millions of hectares primarily in Haryana, Punjab, Rajasthan, and Uttar Pradesh. Proposing aquaculture as a sustainable solution, Dr. Likhi emphasized its economic viability, foreseeing it as a key player in generating income through fish, prawn, and shrimp crops.

Presently, the four north Indian states mentioned produce 8554.15 metric tons annually from 2167 hectares of saline water aquaculture. However, the untapped potential spans 58,000 hectares in these states. Under the Pradhan Mantri Matsya Sampada Yojana (PMMSY), the Department of Fisheries has approved a substantial project for the Genetic Improvement of Common Carp in Inland Saline Aquaculture, with an investment of Rs. 9.29 Crore.

Commending ICAR-CIFE for its commendable genetic improvement program, Dr. Likhi reviewed various activities undertaken by the institution.

Indian Aqua-Feed Sector Explores Benefits of Genetically Modified (GM) Crops for Enhanced Productivity

by Fishery News 30/09/2023
written by Fishery News

In a recent workshop organized by the Biotech Consortium India Ltd (BCIL) and the Central Marine Fisheries Research Institute (CMFRI) under the Indian Council of Agricultural Research, experts discussed the potential advantages of incorporating genetically modified (GM) crops and their derivatives in the Indian aqua-feed sector. The adoption of GM crops is seen as a strategic move to augment the supply of feeding ingredients, leading to improved growth, disease resistance in aqua products, and a reduction in overall production costs.

Dr. Vibha Ahuja, Chief General Manager of BCIL, highlighted the positive impact of using GM crops on aquatic yield. Specifically, she emphasized the role of dried distilleries grains with soluble (DDGS), a by-product of cereals in the distillery industry. DDGS, often derived from GM corn produced in other countries, has the potential to lower shrimp feed prices. Dr. Ahuja pointed out that local production of DDGS for shrimp farms could not only increase profits for feed producers but also contribute to the overall economic growth of the country.

Dr. A. Gopalakrishnan, Director of CMFRI, emphasized the nutritional benefits of incorporating GM crops into aqua-feed. He mentioned GM soybeans as an example, which can produce omega-3 fatty acids crucial for the growth and health of farmed fish. Given that feed constitutes a substantial portion (50-55%) of the total input cost in aquaculture, the efficient use of GM crops in feed production holds the potential to significantly reduce overall production costs.

The workshop participants collectively agreed that the adoption of GM crops in the aqua-feed sector could alleviate pressure on India’s fishmeal and fish oil sectors. This shift aligns with the goal of maintaining a sustainable aquaculture industry while simultaneously benefiting fish farmers and consumers.

Landmark NGT Ruling Puts Nationwide Aquaculture Industry Under Stricter Environmental Scrutiny

by Fishery News 30/09/2023
written by Fishery News

National Green Tribunal (NGT), the aquaculture industry in India is set to face enhanced regulatory oversight with the application of Environment Impact Assessment Notification and inclusion under the consent regime of the Water Act. The NGT’s ruling, dated February 27, stems from an execution application filed by Mumbai-based NGO Vanashakti, which had previously secured an order in May 2021, prompting the formation of a committee to assess the sustainability of inland aquaculture practices.

The NGT has mandated comprehensive regulation, urging authorities to enforce environmental safeguards and scrutinize the impact of aquaculture on water bodies. The ruling emphasizes the need to align inland aquaculture practices with the Environment Impact Assessment regime.

Vanashakti, the NGO behind the legal efforts, underscored the lack of a policy in Maharashtra to regulate inland aquaculture, calling attention to the absence of provisions assessing environmental impacts before granting licenses. The expert committee formed by NGT found tangible evidence of environmental impact in Vadivale Lake, including elevated pollution levels attributed to cage aquaculture activities.

The NGT’s ruling directs the Central Pollution Control Board (CPCB) and Maharashtra Pollution Control Board (MPCB) to bring cage aquaculture under the consent regime within three months. Additionally, the NGT instructs the MPCB to take swift action against individuals contributing to pollution from such activities.

Stalin D, director of Vanashakti, praised the judgment, emphasizing the importance of adapting environmental laws to address emerging sources of pollution. Aquaculture, promoted for enhancing food security and livelihoods, will now undergo increased monitoring, reflecting the evolving landscape of environmental regulations in the country.
