Rain revives fish farming in irrigation tank near Tiruvannamalai
Accompanied by Collector K. Tharpagaraj, Minister for Public Works and Highways E.V. Velu released young fish in the tank on Wednesday as part of fish cultivation by farmers in the region.
Officials of the Tamil Nadu Fisheries Development Corporation (TNFDC), which maintains fish farms in the district, said that fish cultivation, including harvesting, is done during May to August due to the steady reduction of hot weather and gradual rise in water level due to south-west monsoon.
These months also help to retain adequate oxygen in the farming area of the tank due to slow evaporation. Also, as the water level is almost steady, fishing in the waters in the tank remains safe for fishermen. 'Local fishermen from the neighbouring Edapalayam village have been doing the job for many years. Such roping of local skilled workers helps to prevent poaching and also provides jobs for them,' S. Velan, Assistant Director (AD), Department of Fisheries (Tiruvannamalai), told The Hindu.
At Melathikkan tank, Catla, Roya and Mithila are the preferred freshwater fish varieties that are cultivated with acumen, involving local fishermen and officials of the fisheries department. These fish varieties were chosen at least for two reasons - speedy growth and good taste, especially for spicy fish curries. They weighed over one kg in three months after they were left in the tank. As per norms, each hectare of tank area, on average, should release around 2,000 fish should be released to maintain the fish growth in the tank. In other words, 60% of the total area of the tank should be the total number of fish released.
Divided into forenoon and afternoon, fishing in the tank will be done by 18 units of local fishermen, closely monitored by the officials. Each unit has at least two fishermen in a coracle with a target of 20kg per team everyday.
In other words, fishing in the tank should yield at least 0.5 tonnes (500 kgs) daily especially during the peak month of August. These fishermen are paid on a daily basis. Of the total catch, one-third goes for local consumption with the rest goes to the government-run stalls and buyers in the State.

Large number of fish found dead in irrigation tank near Tirupattur town
A large number of fish were found dead in the irrigation tank, which is maintained by the Public Works Department (PWD), at Bommikuppam village near Tirupattur town on Thursday, primarily due to depletion in the oxygen level in the water. Officials of the Department of Fisheries said that most of the fish that were found dead in the tank was Jalebi fish (zoological name: Tilapia fillets). The fish is a common variety from fresh and brackish water bodies. As per estimates, over 50 kg of fish were removed from the tank by the department on Thursday. 'The tank is a key water source for irrigation in the village. Many civic bodies have also dug bore wells around the tank to pump water for domestic consumption. Such sudden death of fishes should be probed and the tank should be cleaned,' said V. Ramu, a resident. Residents and local fishermen alerted the panchayat and Fisheries Department officials after noticing the fish floating along the tank bund. The officials removed the dead fish and collected samples to find the cause of death. Residents said unauthorised discharge of sewage into the tank might also be a major reason for the depletion of oxygen-level in the water, resulting in the death of the fish. Spread over 80 acres, the tank is around 40 feet deep and a lifeline for farmers and residents for irrigation and domestic consumption. At present, the entire tank has been used to cultivate fish for commercial purposes. Revenue generated from auctioning, which is done once in three years, of the lake for fishing goes to the civic body to provide basic facilities in the town. Catla fish, varying from two to four feet, forms the major fish variety. On an average, three tonnes each of major varieties like Catla and Jalebi are netted every year and sold in the local market and in big towns like Tirupattur, Jolarpet, Ambur, Vaniyambadi and Gudiyatham Apart from irrigating more than 1,200 acres of farmland in the area, the tank also helps to provide drinking water to the village residents

Avinashi Road flyover works to be completed by August 15, says Minister
A flyover that is under construction on Avinashi Road in Coimbatore city will be completed by August 15, Minister for Public Works E.V. Velu said here on Saturday. The ₹1,791.23-crore project spans 10.1 km from Uppilipalayam to Goldwins. The Minister told the media the flyover would have eight ramps. Work on one ramp was delayed due to a legal case pending before the Madras High Court. The steel girders above the railway section (near Hope college) was over and the flyover work was progressing. When asked about the absence of pedestrian subways along the flyover, the Minister said such facilities were generally not included in these types of projects. 'The focus is on the main carriageway and the entry and exit ramps. Once the project is completed, if a need arises, we will consider it,' he said. The Minister also inspected the ongoing construction of the Thanthai Periyar Library and Science Centre in the city. He said the construction would be completed by December and the facility was expected to open in January. The library and science centre were developed at a cost of ₹300 crore and would cover 1,98,000 sq. ft. To a question on the Talisman amulet (dhrishti bommai) placed at the construction site, the Minister said he did not support such practices. 'I am a Periyarist and do not encourage these. But the contractors may follow certain beliefs. I do not comment on that. Once the work is completed, there will not be any such structures,' he said.
