Age, growth, and mortality of Opisthonema libertate on the coasts of northwestern Mexico

Abstract

Using readings of 1,214 Pacific thread herring (Opisthonema libertate) otoliths collected at 3 fishing locations off the northwestern coasts of Mexico

Detecting Mugil curema (Perciformes: Mugilidae) phenotypic stocks in La Paz Bay, Baja California Sur, Mexico, using geometric morphometrics of otolith shape, growth, and reproductive parameters

“…However, to corroborate this information, studies are needed that include a detailed following of biological characteristics, as well as studies that focus on the discrimination of phenotypes based on geometric morphometrics (Begg & Waldman, 1999). An example of this is a case study on the Pacific thread herring off the northwest Mexican coast, in which 3 morphotypes that conserved their own growth, reproduction, and mortality parameters were detected (Pérez-Quiñonez et al, 2018;Ruiz-Domínguez & Quiñonez-Velázquez, 2018), coinciding with results from the present study on the white mullet population in LPB.…”

“…The potential presence of population units is evaluated based on the assumption that individuals with high similarity (similar morphotypes) should be closely related, biologically and ecologically (Cadrin et al, 2005). Complementary demographic analyses (e.g., age, growth, reproduction, and mortality) Griffiths, 1997;Ruiz-Domínguez & Quiñonez-Velázquez, 2018) evaluate parameters of biological units (morphotypesstocks) to identify differences in the response of fish to environmental and fishing pressures (Gherard et al, 2013). For this reason, the use of the multiple approaches could provide a better understanding of population structure and dynamics, as was pointed out by Begg & Waldman (1999), who suggested a holistic effort (multiple approaches) to evaluate population structure, in such a way that this integrating approach maximizes the probability of correctly defining fishing stocks.…”

Looking for Parasites as Potential Biological Tags for Pacific Thread Herring, Opisthonema libertate (Günther, 1867) (Clupeiformes, Dorosomatidae), in the Gulf of California

“…Like other small pelagic fish species, O. libertate is ecologically essential due to its role in mediating energy transfer between trophic levels [2,3]. Additionally, this species substantially contributes to the small pelagic fishery in the Mexican Pacific, especially in the Gulf of California [4,5].…”

Use of Pacific thread herring ( Opisthonema libertate ) protein hydrolysates in Nile tilapia ( Oreochromis niloticus ) feeds: Productive performance and antioxidant enzymes on organisms exposed to a heat‐induced stress

“…The Pacific thread herring ( Ophistonema libertate ), is one of the small pelagic species with the greatest commercial importance in terms of catch volume and represents one of the most important fisheries in north‐western Mexico (Ruiz‐Domínguez & Quiñonez‐Velázquez, 2018). This resource is used mainly in the production of fishmeal and fish oil; however, the high‐quality muscle protein of these pelagic fish in terms of content of essential amino acids and digestible compounds, is considered as a quality raw material, which can be used to produce high value commercial products, such as protein hydrolysates (PH; Sandoval‐Gallardo et al, 2020).…”
