ABSTRACT The silky shark ( Carcharhinus falciformis ) has the highest bycatch in gillnets, longlines, and purse seine globally. Its thermal depth preferences coincide with tropical tuna habitat, indicating a high capture vulnerability by these fisheries. present research seeks to determine environmental conditions that favor distribution identify areas probability of occurrence. data analyzed correspond records Eastern Pacific Ocean (EPO) published Inter‐American Tropical Tuna Commission...
ABSTRACT Demographic models are vital tools in fisheries management, particularly for data‐limited species such as sharks and rays. However, a significant gap exists the statistical quantification of productivity metrics related to elasmobranchs. This study addresses this by conducting meta‐analysis population rays, framed within scientometric context. We reviewed 91 publications, which revealed modest positive trend research over time. Our findings suggest that geographical distribution...
The whale shark is the world's largest filter feeding and holds international protection as an endangered species. It known to form seasonal aggregations linked blooms of zooplanktonic organisms. aim this studywas investigate whether foraging behaviors are related density and/or concentration available prey items. Zooplankton samples were obtained between October-2016 March-2017 from Bahia de La Paz in theabsence (n =32) presence = 12) sharks. Results indicated that zooplankton biomass was...
The survey of new benthic substrata is expected to yield records diatom taxa. A particular type substratum the skin Stone scorpionfish Scorpaena mystes Jordan & Starks, 1895 that, because its form life, represents a potential colonizing surface for various organisms, including epizoic and opportunistic taxa (epibiotic community). Thus, floristic diatoms was carried out by sampling epibiotic community from S. specimens collected in east coast Baja California Sur (Gulf California). Thirty are...
The dolphinfish (Coryphaena hippurus) is a globally distributed marine predator that supports one of the most important coastal fisheries along Eastern Tropical Pacific (ETP), but its spatial movements in this area are poorly understood. Stable isotope values (δ13 C and δ15 N) white muscle from (n = 220) captured at different locations across ETP (i.e., Mexico, Costa Rica, Ecuador, Peru oceanic areas) were normalized to copepod baseline stable estimate trophic position, population dispersal....
Abstract Trophic competition among top predators is also influenced by environmental variability. However, the magnitude of changes in contrasting events such as El Niño Southern Oscillation (ENSO) poorly studied. The stomach contents striped marlin ( Kajikia audax ), blue Makaira nigricans and dolphinfish Coryphaena hippurus ) were analysed. We included ENSO effect on diet because we analysed organisms captured during 2010–2011 2014–2015, periods that, according to Ocean Index, defined cold...
Balandra, one of the most popular beaches in La Paz, Baja California Sur, was declared a flora and fauna protection area 2012, 2019, Mexican government chose it as best beach Mexico during Tianguis Turistico celebrated on that year. Because this latter distinction, currently faces overcrowding. Formulating effective management policies depends, to certain extent, knowledge their recreational value visitor characteristics. Recreational allows us know benefits tradeoffs among ecosystem...
Ovaries of bluefin tuna, Thunnus thynnus, from organisms measuring 247.62 ± 3.54 cm fork length collected within the Mexican Exclusive Economic Zone in Gulf Mexico, were examined. The highest gonadosomatic index was recorded April (1.6 0.28), coinciding with presence oocytes a migratory nucleus (oocyte diameter 439 32.84 µm); fully developed gonads also observed two females and males (ovaries or testes, respectively) caught late when sea surface waters exceeded 26 °C. microscopic examination...
The stone scorpionfish (Scor paena mystes) is common throughout the Gulf of California in Mexico.Because little information available regarding basic biological characteristics this species and because commercial demand for it increasing, need studies population dynamics urgent.We sampled 233 (117 males 116 females) from May 2015 through April 2016 to estimate age individual growth.Total lengths (TL) ranged between 15.3 35.5 cm 19.0 44.5 females.Results analysis edge types otoliths (opaque...
