You may be surprised to learn that the opinions expressed herein are bank estimates that global poverty will decrease by 21 million people in 2021. those of the contributors and do not represent the policies or According to the bank, its previous estimates were based on data collected position of NACA. through high-frequency phone surveys as detailed household surveys have, understandably, been put on hold. To generate the most recent estimates, the bank has extrapolated the income and consumption data from past household surveys using national accounts growth forecasts.

Simon Wilkinson I can’t claim to have any data in hand to dispute this fi nding, so feel free to take my [email protected] observations with a large helping of salt. But I admit to being a sceptic. Last year’s lockdowns saved many lives at the expense of a large economic impact (your mileage may have varied depending on where you live and on how strict NACA the lockdowns were).

The otolith weight keeps on increasing because of continuous deposition of material on the otolith surface; therefore, otolith measurements are successfully used to infer fish age. The present study was conducted to estimate the relationship between otolith weight and observed age (estimated by counting annuli on the sectioned otoliths) for the stocks of Sperata aor. A total of 315 samples were collected from January 2016 to April 2017 from three different stocks of S. aor i.e. Narora-Kanpur, Varanasi and Bhagalpur from the River Ganga. Linear regression analysis was applied between otolith weight and observed age to predict the age of the fish of each stock from otolith weight. Significant relationships between otolith weight and fish age were observed for the three stocks of the selected fish species from the River Ganga (R2 > 0.9, P < 0.001). No significant differences were found in the otolith weight among the stocks of S. -

A total of 2419 individuals represented by 18 species belonging to 9 families were sampled between November 2014 and June 2016. The b values ranged from 2.469 for Trichogaster chuna to 3.428 for Ailia coila. All the regressions were highly significant (p<0.001). The results revealed positive allometric growth for seven species (b>3, p<0.05), negative allometric growth for seven species (b<3, p<0.05) and isometric growth for four species (b=3, p>0.05). This study represents the first reference on the length- weight relationship of Trichogaster chuna from a reservoir ecosystem. This is the first report on LWRs of five fish species viz., Puntius terio, Pethia conchonius, Sperata seenghala, Ailia coila and Trichogaster chuna from an Indian reservoir. -

A Review on Sperata Aor (Hamilton, 1822), a Popular Food Fish of Indian Subcontinent
Sains Malaysiana 44(9)(2015): 1217–1222 A Review on Sperata aor (Hamilton, 1822), a Popular Food Fish of Indian Subcontinent (Kajian ke atas Sperata aor (Hamilton, 1822), Ikan Makanan Popular dari Subbenua India) SANDIPAN GUPTA* ABSTRACT Sperata aor is a freshwater catfish of Bagridae family which is distributed throughout Indian subcontinent including India, Bangladesh, Pakistan, Nepal and Myanmar. It is a popular food fish due to its good taste and high nutritional value. Recently it has also made its entry in domestic ornamental fish markets of India and has been reported to have moderate export price too. Earlier, few works on different aspects of its morphology and biology have been carried out but no consolidated review is available on these aspects. Therefore, the current work was done to sum up all available information on these aspects to fill the information gap that will be beneficial to its future fishery. Considering all available information, knowledge on food and feeding habit of this fish species is satisfactory, except detail information on spatial variation of its breeding periodicity, proper information on other aspects are still lacking. No work has been conducted to examine its captive culture potential or for induced breeding. Further work should be done to explore its future fishery. Keywords: Breeding biology; feeding habit; fishery; morphology;Sperata aor ABSTRACT Sperata aor adalah ikan keli air tawar daripada keluarga Bagridae tertabur di sepanjang subbenua India termasuk India, Bangladesh, Pakistan, Nepal dan Myanmar. Ia adalah ikan makanan popular kerana khasiatnya yang tinggi dan baik rasanya. Baru-baru ini ia juga telah menjadi ikan hiasan dalam pasaran tempatan di India dan telah dilaporkan mempunyai nilai harga eksport yang sederhana.
