Biological aspects of spotted seerfish Scomberomorus guttatus (Bloch & Schneider, 1801) (Scombridae) from north-eastern Arabian Sea

Abstract

Spotted seerfish <em>Scomberomorus guttatus</em> (Bloch & Schneider, 1801) is one of the highly priced table fishes in India, which contributed 4.7% of all India scombrid fishery with 17,684 t landed in 2014. Its fishery is dominant in the Arabian Sea and northern Arabian Sea contributed 62% to India’s spotted seerfish fishery. Biological information on <em>S. guttatus</em> is scarce and the same was studied during the period 2010-2014 from Maharashtra coast, north-eastern Arabian Sea. A total of 930 specimens (185-550 mm FL) collected from commercial landings were used for the study. Length-weight relation of pooled sexes was estimated as log (W) = -3.1988+2.66074 log (L) (r2 = 0.93). Fishery was dominated by males with the sex ratio of 0.76:1. Relative fecundity ranged from 105-343 eggs g-1 of bodyweight. The length at first maturity (Lm) was estimated to be 410 mm TL for females. Mature and gravid females were dominant in May and August-November. Dietary studies (% IRI) showed dominance of <em>Acetes</em> spp.

PRELIMINARY STUDY ON BIOLOGICAL ASPECTS OF PAPUAN SEERFISH (Scomberomorus multiradiatus MUNRO, 1964) IN MERAUKE WATERS, PAPUA, INDONESIA

“…Scomberomorus guttatus, which is in the same genus with S. multiradiatus showed isometric growth in the Cilacap and adjacent waters (Restiangsih et al, 2016) and Moro waters part of Kepulauan Riau (Noegroho et al, 2018), while Anulekshmi et al (2018) found that S. guttatus from north-eastern Arabian sea had an negative allometric growth. The differences in the fish growth pattern could be caused by the biological factors such as gonadal development, feeding habit, growth phase and sexes (Froose, 2006;Tarkan et al, 2006) and ecological factors such as season, water quality, temperature, salinity, acidity (pH), geographical position and sampling techniques (Zargar et al, 2012).…”

Fisheries characteristics and biology of Indo-Pacific King Mackerel in Tarakan Waters, North Kalimantan

“…The frequency distribution of the length of the mackerel (Scomberomorus gutatus) ranged from 23 cm to 55.4 cmFL, with a length mode of 25.1-24.9 cmFL. [22]; [23]; [24]; [25]; [26]; [27]; [28]. The mode value shows that the fish caught are dominated by large fish or have mature gonads.…”
