Fish ponds in Ranchi drying up due to concretisation of roads


Concretisation of roads is leading to an ecological disaster because, the flow of water from surrounding areas to fish ponds are disturbed and, as a result, fish ponds in Ranchi are drying up. The rising temperatures and dipping water-levels are posing a serious threat to fish at breeding centers in Ranchi which, in turn, is affecting the availability of fish.
This has been reported in telegraphindia.com dated 20 April 2016.
In Ranchi, the fish ponds at Doranda's Machli Ghar and Dhurwa's Shalimar training center have started to dry up due to not only the scorching heat, but the concretisation of roads that has blocked the flow of water into these natural receptacles for the last few years. As indicated by State fisheries department officials, three out of the 12 ponds at Machli Ghar are already parched and the water levels of the other ponds has reduced alarmingly to 1.5ft.
Moreover, the level of water in all the 24 ponds at the fisheries department's training center in Dhurwa have dipped from 7ft to 1ft and, as a result, both the centers have shifted the fish to reservoirs. The reduction in water-level is also due to abnormal warming of water and this is lethal for survival of spawns (fish seeds).
Incidentally, nearly 30-32 tonnes of fish spawns are bred annually at the Doranda firm and 45 tonnes at the Dhurwa facility. These spawns are bred and reared in a controlled environment after which they are released into big reservoirs and water bodies across the state. According to experts associated with fish production since long, the major problem was poor civic planning over the years which resulted in catchment areas not getting sufficient water which, in turn, has affected the water bodies.

Buffalo hits SpiceJet Boeing-737 aircraft on Surat airport runway – 146 passengers safe


A buffalo hit a SpiceJet Boeing-737 aircraft on Surat airport runway as it was about to take-off for Delhi – fortunately, the 146 passengers on board were safe due to the timely evasive action taken by the pilots.
A high-level meeting convened by aviation minister Ashok Gajapathi Raju Pusapati have discussed the issue of stray animals at airports which is a common occurrence in India. Both the DGCA and Airports Authority of India are investigating this serious incident.
The aviation ministry has taken an immediate decision to send teams to all airports to inspect the perimeter fences and boundaries and ensure replacement of all barbed wires fences by boundary walls to prevent animals from straying into airports for grazing.
The target set is next three months – whether this timeframe is for dispatch of teams or for constructing boundary walls is not very clear.
It has also transpired that there are fish ponds in the vicinity of the runway – these attract birds and lead to another menace for aircraft because bird hits can destroy aircraft.
Animal intrusions at runways have been a common affair. Last month a jackal was trapped from near the Kochi runway. In May, 2012, a pig on Nagpur runway prevented an IndiGo aircraft from landing and the plane had to go around. Incidents of animals on runways in 2008 at Kolkata and Bangalore airport – initially the quartet of jackals looked like dogs from the cockpit of an aircraft readying for takeoff and it resulted in two other planes to hover above the airport for an extra 15 minutes and burn fuel worth about Rs 63,000 each.
On March 27, a Kingfisher Airlines aircraft ran into a dog on the runway of Bangalore airport during take-off – it resulted in the collapse of the nose landing gear. The crew evacuated the 25 passengers on board after the aircraft screeched to a halt.
