Length‐weight relationships of 10 coastal fish species from the Visakhapatnam coast, India

Abstract

We analysed the length‐weight relations (LWRs) of 10 fish species inhabiting different habitats from Visakhapatnam, Coast of India. Samples were obtained between August 2013 and December 2016 from commercial trawlers at the local fish landing centre (16.98°N–20.20°N, Long.82.19°–86.53°E). Fishes were captured between 100 and 300 m depth with demersal trawl net (head rope length: 46 m and cod end mesh size: 40 mm with a 38 m high speed. Total length (TL; nearest to 0.1 cm) and body weights (nearest to 0.1 g) were taken from each individual. This study provides new maximum length data for two species (Archamia bleekeri (Günther, 1859) and Ostorhinchus fleurieu (Lacepède, 1802), and LWR estimates for rare deep reef associated fishes are provided for the first time. All LWRs were significant with r2 values ranging from .908 for Sargocentron praslin (Lacepède, 1802) to .981 for Parapercis pulchella (Temminck & Schlegel, 1843) and “b” values ranged from 2.5216 for Parapercis pulchella (Temminck & Schlegel, 1843) to 3.4746 for Ostorhinchus fleurieu Lacepède, 1802.

New Distributional Record of Triacanthus nieuhofii Bleeker, 1852 (Tetraodontiformes: Triacanthidae) from Maharashtra, North West Coast of India

“…The soft fins of the fish are a yellowish colour. Previously it is reported in India from Lakshadweep (Jones and Kumaran, 1968), Kerala (Naomi et al, 2011), Goa (Hegde et al, 2013), Tamil Nadu (Karuppasamy, 2016), Odisha (Karna et al, 2018), West Bengal (Mohanty et al, 2018) and Andhra Pradesh (Naranji et al, 2019). Globally, it is reported from the Arabian Sea, Bay of Bengal, Andaman Sea, Indonesia, South China Sea, and northern Australia (Matsuura, 2015).…”

Length–weight relationships of four fish species from Zhoushan, China

“…The analysis results of Johnius fasciatus in this study are basically consistent with those of Lei et al 5 The parameters of these assessments should be measured only as annual averages for these species, as the data are collected over a considerable period of time and do not represent any particular season. 7 In a word, this study provides basic LWR data of four kinds of fish species, and provides a certain reference value for the reasonable development and protection of Fisheries in Zhoushan of China. Further research is certainly needed, including more parameters than length and weight, in order to better understand and manage fisheries resources in this highly valuable ecosystem.…”
