COMMON NAMES

Slender thread herring

Slender thread herring (Opisthonema bulleri) is found from Magdalena Bay in Gulf of California, Mexico to northern Peru (SAGARPA, 2012). According to Bakun et al. (2009), the Gulf of California is intermittently subject to important influxes and major exchanges of small pelagic forage fishes, such as Opisthonema bulleri, both northwards and southwards the mouth of the gulf. However, others assume that the gulf stocks are separate from the West Coast (Chávez and Chávez-Hidalgo, 2013).

In the Sonora region, this species is captured in a very low proportion (as compared to the dominant species, the Pacific thread herring). In the southern Gulf, in Sinaloa and Nayarit, the proportion of the three Ophistonema species is more similar and assessment is conducted separately (Morgan et al. 2016). Therefore, an assessment unit is considered in Sinaloa and Nayarit for slender thread herring. 


ANALYSIS

Strengths
  • The fishery management instruments have improved in recent years, through the approval of a fishery management plan and update of regulations within the Carta Nacional Pesquera, and a new regulation for the fishery of small pelagic species promulgated in 2019 (SADER 2019).
