“…The negative allometric growth observed for P. medius in the present study was also recorded by several authors, such as Vera et al (2006) 2009) on the west coast of Baja California Sur, Mexico, reported a value of b = 3.07 that did not differ from 3 (P > 0.05), and this difference could be attributed to the small size of evaluated individuals, in the range 12-18.7 cm TL. Values of b parameter smaller than 3 have been reported in other species of the same genus, like P. crenulatus in estuarine areas of northeastern Brazil, b = 2.57 (Fernandes et al 2020) and P. paru in southern Brazil (Haimovici & Velasco 2000).…”

In Ecuador, Peprilus medius is an important fishery resource whose destination is for local consumption and export. There are few local studies on its reproductive biology, and its capture is not regulated. Therefore, this study evaluates the most relevant aspects of its reproductive activity. Samples were obtained monthly from January to December 2017 from the capture of the purse seine fleet and the artisanal gillnet fleet landing near Manta. The morphometric analysis included the length-weight relationship, estimated using the allometry equation. The size at sexual maturity is based on the L50 criterion; the reproductive cycle was determined according to the monthly analyses of the gonadosomatic index (GSI), hepatosomatic index (HSI), and relative condition factor (Kn). A total of 334 specimens were analyzed, with average sizes of 22.0, 21.87, and 21.91 cm of total length (TL), for males, females, and combined sexes, respectively. Sex ratio was 1.17M: 1F (P > 0.05), while the length-weight relationship showed negative allometric growth for both males and females (b = 2.58; CI95% 2.48-2.72). Size at sexual maturity L50 was estimated at 21.84 and 21.23 cm TL for males and females, respectively. The GSI and HSI values and Kn showed significant differences among months (P < 0.05), with a marked seasonality during the single reproductive period. Mean size at first capture of 21 cm TL is recommended.

Oligoplites saliens é uma espécie costeira que ocorre no oceano Atlântico ocidental, de Honduras ao Uruguai. É amplamente distribuída com registros ao longo de todo litoral brasileiro. A espécie é frequente e abundante e ocorre na pesca comercial artesanal ou industrial, estando contida na categoria guaivira ou salteira. Os juvenis são encontrados em áreas estuarinas rasas, sendo que parte de sua distribuição é impactada localmente pela degradação do hábitat. No entanto, estas ameaças não foram consideradas importantes ao ponto de colocar a espécie em risco de extinção e não existem indícios de declínios populacionais, categorizando O. saliens como Menos Preocupante (LC).
