“…Subsequently, a one‐way analysis of variance (ANOVA) was performed to ascertain whether there were any significant differences (α = 0.05) among the various fishing gears reported in both study sites. To determine which means differed (α = 0.05), Tukey's multiple test of means was utilized (Berenson et al, 2001).…”

The Pacific seahorse (Hippocampus ingens) is a teleost fish native to the Pacific Ocean. In Mexico they are protected by national legislation; however, there are no studies regarding their commercial use or population status. From a conservation perspective they are a threatened fish and from a socio‐economic aspect they represent a source of income for many fishing communities. The integration of these two points of view requires, among other things, the recognition that fishers have knowledge and skills that can help implement conservation strategies and management plans for seahorses and their habitats. The objective was to document the knowledge of fishers from Sinaloa about the fishing status and current commercialization of wild populations of H. ingens. For this, semi‐structured interviews and participatory observation were carried out with 112 participants in the two main ports of the state of Sinaloa (Mazatlán and Topolobampo) from July to August 2021. The data obtained were coded and then, through content analysis, systematized results were obtained that allowed a qualitative and quantitative analysis. The species was found to be caught using six different fishing gears (catch per unit effort, CPUE = 0.07–1.24 seahorses per boat per day) and have an important financial value. Most fishers catch seahorses incidentally, but three of them mentioned targeting them directly. Fishers perceive a decrease in catches and in the size of the Pacific seahorse, as well as an increase in prices. The information analysed indicates that seahorse populations in Sinaloa are exploited and have economic value, despite current regulations. This study shows that the exploitation of seahorses in Sinaloa is unsustainable and requires the implemention of collaborative management strategies (e.g. stakeholder management, the establishment of marine protected areas, sustainable harvest practices, community‐based enforcement efforts, educational campaigns, research, and conservation partnerships) that fully take into account the knowledge and practice of local fishers of Sinaloa and Mexico.

“…Con base en Berenson & Levine (2006), cuando la población tiene una distribución normal, la distribución muestral de la media está distribuida de manera normal para cualquier tamaño muestral. En virtud de la propiedad de imparcialidad, la media de toda distribución de la muestra siempre es igual a la media de la población.…”
