Little information is available regarding changes in oceanographic variables at the mesoscale level in the CMP. Therefore, this study characterized 6 oceanographic variables (sea surface temperature, chlorophyll concentration [Chl], primary productivity [PP], diffuse attenuation coefficient [K490], and particulate inorganic/organic carbon concentration [PIC, POC]) in the CMP from 2010 to 2017 and their relationships with El Niño/Southern Oscillation (ENSO). The variables were standardized to monthly pixel values of 0.08 latitude degrees, and the study area covered 48,846.48 km2. Friedman tests were used to compare the temporal variation in the variables, while Spearman correlations were used to evaluate the relationship between each variable and the Multivariate ENSO Index (MEI). A cross-correlation analysis was performed to determine the temporal lag between the oceanographic variables and the MEI. The cyclicity of the variation in the CMP was determined by spectral analysis. All variables showed significant differences between months and years. Two seasons defined by temperature were also detected: a cold season (December–June), in which high values of these variables were observed, and a warm season (July–November), in which low values of these variables were observed. No variables were correlated with the MEI; however, a 4-month time lag was identified between the variables and the MEI. The cyclicity of the variables corresponded to the cold and warm seasons. The cold phase of ENSO increased the values of PP, Chl, and K490 up to 4 times compared to those of other years. Taken together, the observed variation in oceanographic conditions makes the CMP one of the most dynamic coastal regions of the Mexican Pacific.","PeriodicalId":50702,"journal":{"name":"Ciencias Marinas","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2023-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47908591","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

El estudio contempló la medición de variables hidrográficas, químicas y biológicas en la capa superficial del área de estudio. Nuestros resultados mostraron una columna de agua cálida, fuertemente estratificada, empobrecida en nutrientes y con biomasas fitoplanctónicas reducidas (<1 mg Cla·m–3).

The aims of this study were to assess the reproductive potential and the potential rate of population increase (rʹ) of both species, as well contrasting their reproductive strategies, to infer how susceptible they are to fishing exploitation. Comparatively, among batoids, N. entemedor females have an early age at maturity, relatively high fecundity, and an intermediate lifespan, while R. steindachneri females have an early age at maturity, low fecundity, and a relatively short lifespan. According to our estimates, however, both species have relatively high reproductive potential, which N. entemedor exhibits by investing energy in maximizing fecundity and R. steindachneri by increasing the embryo’s body mass. Therefore, N. entemedor has better capacity to recover from relatively high overfishing (rʹ = 0.48) in comparison with R. steindachneri (rʹ = –0.18). The methodology used in this study proved to be a good option to assess the risk of overfishing in species for which there is limited data.","PeriodicalId":50702,"journal":{"name":"Ciencias Marinas","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2023-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48778517","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We analyzed the influence of 3 harvest densities (15, 20, and 22 kg·m–3) on the growth of spotted rose snappers reared in floating net cages during a production cycle. To assess the impact of stocking density on growth performance, we used 2 indicators: final total length-at-age (12 months) and the growth rate estimated from growth models (von Bertalanffy, logistic, and Gompertz). For the first indicator, we tested for normality. We did the Kruskal–Wallis and the post hoc Kruskal–Wallis tests to compare the mean total final length from each density. Accordingly, the means of densities D15 and D20 were the same (P value = 0.22). For the second indicator, we fitted the models with the subroutine optim of the R statistical package using the L-BFGS-B algorithm. Model selection was made with the Akaike and the Bayesian information criteria. Both criteria suggested that the logistic model fitted the data best. With the best model (logistic), we did 1,000 bootstrap simulations for each density scenario to determine the distribution of the maximum likelihood estimation for the instantaneous growth rate. Because the estimates were normally distributed, we used ANOVA to test the equality of the instantaneous growth. The Tukey HSD test suggested that all means were statistically different from each other. The fastest growth rate (K = 0.275) corresponded to the cage with a density of 20 kg·m–3. These findings demonstrate that the logistic model can predict the growth of spotted rose snappers under culture conditions using floating net cages. These results strengthen the productive potential and economic profitability of snapper aquaculture using floating cage and may help the start of commercial scale aquaculture.","PeriodicalId":50702,"journal":{"name":"Ciencias Marinas","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2023-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45636020","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Durante 2 campañas oceanográficas en invierno de 2006 y verano de 2009, se determinó la estructura física de la columna de agua mediante un CTD y se recolectaron muestras de zooplancton mediante arrastres oblicuos. Se utilizaron datos de satélite para visualizar los patrones de distribución de clorofila a (Cla). Los resultados mostraron un vórtice ciclónico en ambas estaciones, con un diámetro de ~25 km y velocidades geostróficas >50 cm·s–1 en su periferia, con elevada Cla (~3 mg·m–3 en invierno). La máxima biomasa de calanoides ocurrió en invierno, con hasta 6.6 mg·100 m–3 en el oeste de la bahía, cerca de la costa; además, su distribución coincidió con el patrón de Cla y circulación, ya que formó un anillo siguiendo la periferia del vórtice, con un segundo pico cerca de la conexión con el golfo. Los valores medios de biomasa de copépodos mostraron un patrón de alternancia calanoides-ciclopoides entre invierno y verano dentro del vórtice ciclónico, con más biomasa de calanoides que ciclopoides en invierno y lo contrario en verano.
