Indian mackerel (Rastrelliger kanagurta Cuvier, 1817) is a small pelagic fish species which is the main catch commodity in purse seine and jukung fleets in the Bali Strait waters. Sustainable management is urgently needed for indian mackerel populations in Bali Strait waters to remain sustainable fishery. The availability of basic information such as biological aspects is very important as a fundamental resource in the management of indian mackerel in Bali Strait waters. The aims of this study were to reveal several biological aspects of mackerel such as growth patterns, condition factors, sex ratio, and size at first maturity of indian mackerel in Bali Strait waters. Sampling was carried out in May-September 2018. Samples of fish were taken from purse seine and jukung fleets using trawl nets and gill nets. Fish sample was measured, weighed and dissected to observe the sex and the gonadal maturity stage. The total number of indian mackerel samples was 167 individuals. Mackerel in the Bali Strait waters has a positive allometric growth pattern with fish in good condition. The sex ratio was in an unbalanced condition with the number of male fish being more than the female fish. The size at first maturity was 19.34 cm for male fish and 19.76 cm for female fish.

Length–weight relations (LWRs) were estimated for 44 fish species, representing 23 families, collected from an unprotected coastal biological corridor of the Yucatan Peninsula. The following species were studied (in alphabetical order): Acanthostracion quadricornis (Linnaeus, 1758); Albula vulpes (Linnaeus, 1758); Anchoa hepsetus (Linnaeus, 1758); Anchoa lamprotaenia Hildebrand, 1943, Anchoa lyolepis (Evermann et Marsh, 1900), Anchoa mitchilli (Valenciennes, 1848); Archosargus rhomboidalis (Linnaeus, 1758); Ariopsis felis (Linnaeus, 1766); Bagre marinus (Mitchill, 1815); Bairdiella chrysoura (Lacepède, 1802); Caranx latus Agassiz, 1831; Chaetodipterus faber (Broussonet, 1782); Chriodorus atherinoides Goode et Bean, 1882; Cynoscion arenarius Ginsburg, 1930; Elops saurus Linnaeus, 1766; Eucinostomus argenteus Baird et Girard, 1855; Eucinostomus gula (Quoy et Gaimard, 1824); Eucinostomus harengulus Goode et Bean, 1879; Harengula jaguana Poey, 1865; Hyporhamphus unifasciatus (Ranzani, 1841); Lagodon rhomboides (Linnaeus, 1766); Lutjanus griseus (Linnaeus, 1758); Menticirrhus americanus (Linnaeus, 1758); Menticirrhus littoralis (Holbrook, 1847); Menticirrhus saxatilis (Bloch et Schneider, 1801); Mugil curema Valenciennes, 1836; Mugil trichodon Poey, 1875; Oligoplites saurus (Bloch et Schneider, 1801); Opisthonema oglinum (Lesueur, 1818); Opsanus beta (Goode et Bean, 1880); Orthopristis chrysoptera (Linnaeus, 1766); Prionotus tribulus Cuvier, 1829; Rypticus maculatus Holbrook, 1855; Selene vomer (Linnaeus, 1758); Sphoeroides spengleri (Bloch, 1785); Sphoeroides testudineus (Linnaeus, 1758); Strongylura notata (Poey, 1860); Strongylura timucu (Walbaum, 1792); Symphurus plagiusa (Linnaeus, 1766); Synodus foetens (Linnaeus, 1766); Trachinotus carolinus (Linnaeus, 1766); Trachinotus falcatus (Linnaeus, 1758); Trachinotus goodei Jordan et Evermann, 1896; Urobatis jamaicensis (Cuvier, 1816). A new maximum standard length (SL) was recorded for Anchoa lamprotaenia. Positive allometric growth was reported in ten species, negative allometric growth in sixteen species, and isometric growth in eighteen species.
