The influence of the 1992-1993 el niño on the reproductive biology of Scomber japonicus peruanus (Jordán & Hubb, 1925)

Abstract: The influence of the 1992-1993 El Niño events on the reproductive behavior of the Scomber japonicus peruanus (Chub mackerel) was studied from samples collected monthly, along the Peruvian coast (3º23'S-14º00'S), from January 1990 to December 1993. The monthly variation of the gonadosomatic index and the frequency of the periods of gonad maturation evidenced that the spawning of the species occurred all year long, being more intense in summer. The values of the gonadosomatic index were higher during the occurre… Show more

“…In general, pelagic fish such as S. japonicus spawn in areas with substantial biological production, to ensure adequate adult and larval feeding (Blaxter and Hunter, 1982; Caramantin‐Soriano et al., 2009). Furthermore, one of the main triggers of spawning activities in chub mackerel is the water temperature (15–20°C; Collete and Nauen, 1983).…”

“…The reproduction biology of chub mackerel has been thoroughly investigated in the Atlantic and Pacific oceans (Parrish and Knaggs, 1971; Knaggs and Parrish, 1973; Dickerson et al., 1992; Ermakov, 1996; Martins, 1996; Yamada et al., 1996; Gluyas‐Millan and Quinonez‐Velazquez, 1997; Watanabe and Yatsu, 2004; Caramantin‐Soriano et al., 2009; Shiraishi et al., 2009). In contrast, information is rather limited and fragmentary for the Mediterranean stocks (Tuggac, 1957; Demir, 1961; Baird, 1977; Kiparissis et al., 2000).…”

“…Así, según lo establecido por Buitrón et al (2011), se consideró como hembras inmaduras a aquellas con estadios I -II y maduras III -VIII. Así mismo, para el análisis, solamente se incluyeron los meses entre noviembre y marzo, momento en el cual ocurre la mayor actividad reproductiva (Caramantin-Soriano et al 2009). Este periodo se consideró como la principal época reproductiva de la caballa.…”

“…Sus desembarques máximos se dieron a fines de los 90's con 380 mil toneladas, siendo las magnitudes promedio en los últimos 3 años alrededor de las 90 mil toneladas (PRODUCE 2017). Los estudios de esta especie en el Perú estuvieron relacionados principalmente a su crecimiento, mortalidad (Mendo 1984, Caramantín-Soriano et al 2008, fecundidad (Peña et al 1986, Buitrón y Perea, 1998 y algunos aspectos reproductivos (Caramantin-Soriano 2001, Caramantin-Soriano et al 2009. En cuanto a estudios relacionados a la estimación de talla de madurez y de desove se tiene el trabajo de Miñano y Castillo (1972) y Mendo (1984).…”
