Four-year-old Dhanvi from Kozhikode helps discover subterranean eel loach
KOZHIKODE: In a remarkable blend of childhood curiosity and scientific curiosity, a four-year-old girl has become the unlikely face behind the discovery of a new subterranean fish species from Kerala. Dhanvi Dheera, fondly called Juhu, first noticed the unusual fish while playing with water collected from a well in their house during a visit to Naduvannur in Kozhikode district. Her observation prompted her mother Aswani Lalu to investigate further, which eventually led to a groundbreaking scientific revelation.
Aswani, who used to draw water from a dugout perennial well owned by Malol Karthiayani Amma, noticed the tiny eel-like fish and informed local experts. The well, situated at an elevation of 150 m above sea level, receives continuous underground water flow from the hilly terrains of Vallora Mala and drains through a natural subterranean channel, making it an ideal habitat for rare aquatic life.
Responding to the find, a scientific team led by Dr K R Sreenath, Director General of the Fisheries Survey of India, and Dr B Pradeep of Krishi Vigyan Kendra, Kozhikode, collected specimens. Detailed morpho-meristic and genetic analysis confirmed that the fish represented an entirely new species. The eel loach was officially named Pangio Juhuae, in honour of little Juhu who first spotted it.
Their research was published in the Indian Journal of Fisheries, under the title 'Discovery of a new species of troglobitic eel loach from Southern India'. The study was co-authored by scientists Dr K R Aju, Dr Sandhya Sukumaran, Dr Wilson Sebastian, Dr Alvin Anto and Dr Grinson George.
This marks the third discovery of a subterranean eel loach species in Kerala in recent years. Pangio Bhujia was first identified in 2019 from Cherinjal in Kozhikode, followed by Pangio Pathala from Tiruvalla in Pathanamthitta district in 2022. However, Pangio Juhuae stands apart with its distinct dorsal fin and more pronounced eyes, suggesting it has retained more surface-dwelling traits than its cousins.

Rare wild mushroom discovered in Arunachal's Longhua village
Longding: A large wild mushroom, tentatively identified as Infundibulicybe gibba (formerly Clitocybe gibba), a well-known edible species, was discovered in the moist, shaded bamboo structures of Longhua village in Longding district of Arunachal Pradesh on Wednesday. The mushroom was identified based on its distinct morphological characteristics by Deep Narayan Mishra, a subject matter specialist (plant pathology) at Krishi Vigyan Kendra, Longding. According to Mishra, the specimen exhibited typical features such as a pale, funnel-shaped cap, decurrent gills, a central stipe and growth on decomposing organic matter. These traits align with those commonly observed in Infundibulicybe species, which are generally found in temperate and subtropical forested regions and are known for their edibility and nutritional benefits, he said. In several tribal and rural communities, such mushrooms are traditionally consumed for their protein, fiber and mineral content. However, Mishra cautioned that the current identification is only tentative and should not be considered conclusive without laboratory confirmation. He stressed the importance of scientific validation through methods such as internal transcribed spacer (ITS) DNA sequencing, spore print analysis to assess colour and pattern and microscopic examination of spores and hyphal structures. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Memperdagangkan CFD Emas dengan salah satu spread terendah?

He also advised that any wild mushrooms intended for consumption must be properly identified, thoroughly cleaned, and cooked — either by boiling or frying — to eliminate any harmful compounds that may be present. Mishra emphasised that this discovery reflects the rich biodiversity of the Longding area and presents opportunities to raise community awareness about wild edible mushrooms. It also offers potential for sustainable harvesting and further scientific research, which could enhance food security, nutrition, and income generation for rural and tribal populations in the region.

Providing scientific solutions to farmers' challenges
Tadepalligudem (West Godavari District): The Viksit Krishi Sankalp Abhiyan (VKSA) which is scheduled from May 29 to June 15 is being conducted by Krishi Vigyan Kendra (KVK), Venkataramannagudem, under Dr YSR Horticultural University. It was a flagship outreach initiative by the Government of India aimed at empowering farmers ahead of the Kharif season. VKSA was spanned 45 villages in 25 mandals of East Godavari, West Godavari, and Eluru districts, reaching out to 16,262 farmers. Dr P Vijaya Lakshmi, Principal Scientist at KVK, VR Gudem, served as the nodal officer, with a team of scientists including Dr Pedababu, Dr Rekha, Dr Prasad Reddy, and Dr Deepthi. Scientists from Indian Institute of Oil Palm Research (IIOPR), Pedavegi, Dr Ramachandrudu, Dr Mary Rani, and Dr Premalatha also participated. The key focus of VKSA is on enhancing farmer incomes through scientific agricultural practices. During interactive sessions, the scientists stressed the importance of choosing climate-resilient and high-yielding varieties such as Bhima MTU-1140 and MTU-1232 as alternatives to the commonly grown Swarna variety. They also advocated for organic cultivation methods, soil testing, soil fertility enhancement techniques, and the adoption of oil palm as a major source of revenue. Special focus was laid on horticultural crops like coconut, cocoa, oil palm, banana, mango, cashew, and vegetables, all of which are increasingly affected by climate change, nutritional deficiencies, and pest attacks such as spiralling whiteflies. The initiative was carried out in close coordination with officials from the departments of Agriculture, Horticulture, Animal Husbandry, and Fisheries, with support from local political leaders and active participation from the farming community. Dr Vijaya Lakshmi expressed satisfaction over the successful execution of the programme and the overwhelming response from farmers. 'We are glad to have directly reached thousands of farmers and provided scientific solutions to their field-level challenges,' she said.

Scientists teaching farmers new techniques to increase production: Shivraj
Motihari: Union minister of agriculture and farmers welfare on Monday said that more than 2,000 scientists would visit around 700 districts to teach over 1.5 crore farmers the use of modern technologies in allied farming under nationwide 'Viksit Krishi Sankalp Abhiyan' (VKSA). Tired of too many ads? go ad free now Aiming to transform agriculture and fisheries by promoting advanced technologies in the sector, the central govt has launched nationwide VKSA, being held from May 29 to June 12, as part of which Chouhan was in the state on the day. "Our government has connected the agricultural scientists with farmers to make them aware of new techniques to raise production," he said while addressing a meeting of farmers in Krishi Vigyan Kendra (KVK) at Piprakothi in East Champaran district, adding this was the place where Mahatma Gandhi held his satyagraha for the first time against the British tax on poor farmers. "This place is the 'karmabhoomi' of Bapu. I am also a servant of people and have been doing work for the betterment of farmers and workers," he said. He also laid the foundations stones of several agricultural projects worth Rs 6 crore on the premises of the KVK at Piprakothi. "The teams of scientists will visit your doorstep to make you aware of modern technologies in allied farming," he told farmers. He praised the KVK of Piprakothi for doing "commendable work among the farmers" and being the foremost in Bihar. Besides, he praised the work done by former agriculture minister Radha Mohan Singh, who is also the Purvi Champaran MP. Singh said that the KVK at Piprakothi stands at the same place where farmers were once tortured by the "saheb of the kothi" (British officer). Now, it has turned into a temple for farmers, he said. State jal shakti minister Raj Bhushan Nishad, cane industry minister Krishnanandan Paswan and agriculture secretary Sanjay Kumar Agarwal were also present at the function.
