Temporal morphometric analyses of Pila globosa in India for its use in aquaculture and food industry

Abstract Background Although the apple snail Pila globosa is used as indicator species for human consumption locally and fish feed, research on it in general very scanty. It food industry, aquaculture bait many regions of India other countries, but has been started 1970s. Only 40 articles are available this organism PubMed indicating an urgent need basic especially work its spatiotemporal morphometry Therefore, sampling P. was done from different parts seasons (summer, winter rainy), morphometric studies were performed to draw baseline information. Analysis conducted study morphometry, relationship between shell length weight relative condition factor Indian collected five zones (east, west, north, south centre) during 2018–2019 year. Results The (SL) (46.5 ± 13.33), width (SW) (40.22±11.5 mm), spire (SPL) (2.99±0.15 base (BL) (12.53±2.94 aperture (AL) (21.95±4.36 (AW) (2.74±0.47 mm) (WT) (31.08±13.76 g) observed be varied among individual sampled across India. Different relationships SL/SW (Log SW=0.9889 Log SL + 0.9444), SL/SPL SPL = 0.1452 SL+0.3815), SL/BL BL=0.7789 SL+0.5814), SL/AL AL= 0.6518 SL+0.9111) SL/AW AW=0.4475 SL+0.1422) by considering index. found WT=2.0263 SL+0.1098. revealed uninterrupted good environmental snails. A negative allometric growth pattern length–weight relationship. Conclusion environments not contaminated, results can data model analysis a reference drawing indices India, there no such information it. also mass scale production use aquatic industries feed.
