“…No se descarta la acción o influencia directa de la variabilidad del medio electromagnético natural en la reproducción, la fertilidad, el estrés y otros parámetros puramente biológicos de los crustáceos bajo estudio ya que se han encontrado numerosas evidencias de que numerosos objetos vivos reaccionan sensiblemente a los cambios electromagnéticos del medio en que viven, sobre todo a las frecuencias muy bajas (Nyqvist D. et al 2020;Litovitz et al 1992;Gmitrov y Ohkubo 2002;Kumosani y Qari 2003).…”

Es creciente el interés por conocer los vínculos entre el comportamiento de la Actividad Solar (AS) y del Clima Espacial con numerosos procesos de la biosfera y en particular, los relacionados con la extracción de especies marinas de importancia económica. En este trabajo se relacionó la serie de tiempo anual (1959-2018) de captura de langosta por varias cooperativas pesqueras a lo largo de la Península de Baja California, México, con los ciclos multianuales de la AS, con el objetivo de revelar si se cumple la hipótesis de asociación entre estas variables. La relación estadística y análisis espectral (Transformada Rápida de Fourier -FFT) entre las dos series de tiempo muestran un marcado sincronismo y la presencia, en los volúmenes de captura, del período principal de 11 años de la Actividad Solar. Se explica la posible conexión AS-clima-océano con la variabilidad pesquera del crustáceo en la región citada. Teniendo en cuenta los volúmenes de captura de langosta y la importancia económica que ello constituye para la región, se considera un aspecto importante para su posible aplicación práctica y explotación de este conocimiento en el marco de la tendencia en los ecosistemas debido a la variabilidad climática y el impacto del cambio climático, seguramente con posible extrapolación a otras áreas del continente y países aledaños.

“…This was, however, a highly questionable practice, as was pointed out by both the industry and the scientific community. A literature study was initiated and the results indicated that the main EM disturbances to fish species are likely to occur during their navigation during migration [43]. In accordance with the general goal of the recommendations: to prevent recruitment failure, the migration towards spawning grounds was considered to be most important to protect.…”

Anthropogenic noise has been recognized as a source of concern since the beginning of the 1940s and is receiving increasingly more attention. While international focus has been on the effects of noise on marine mammals, Norway has managed seismic surveys based on the potential impact on fish stocks and fisheries since the late 1980s. Norway is, therefore, one of very few countries that took fish into account at this early stage. Until 1996, spawning grounds and spawning migration, as well as areas with drifting eggs and larvae were recommended as closed for seismic surveys. Later results showed that the effects of seismic surveys on early fish development stages were negligible at the population level, resulting in the opening of areas with drifting eggs and larvae for seismic surveys. Spawning grounds, as well as concentrated migration towards these, are still closed to seismic surveys, but the refinement of areas and periods have improved over the years. Since 2018, marine mammals have been included in the advice to management. The Norwegian case provides a clear example of evidence-based management. Here, we examine how scientific advancements informed the development of Norwegian management and how management questions were incorporated into new research projects in Norway.

“…Seeing how well these animals are navigating, the question emerged which sensory information the seals and other marine mammals use for orientation and navigation. Theoretical speculation sprouted over the use of stars or the Earth's magnetic field [6][7][8]; while the first is based on good preliminary experimental evidence [9,10], magnetoreception has not been documented for seals [11]. In general, previous experiments regarding orientation and navigation in seals almost exclusively focused on cues perceived by the classic sensory systems, such as visual, auditory, chemoreceptive or hydrodynamic cues [12][13][14].…”

Harbor seals commute between haul-out places and feeding grounds close to the shore or in the open ocean, which is considered a low structured environment, at first sight not providing many cues for orientation/navigation. Nevertheless, seals are well-oriented. For returning to a specific location, seals may use both external and internal cues to, for example, perform path integration requiring the integration of distances traveled and angles steered. We herein assessed the seal’s ability to estimate distances, previously swum or unknown, in reproduction tasks. Reproduction tasks refer to an experimental paradigm in which the experimental animal is required to swim a specific distance first and subsequently reproduce this distance, with visual cues present or absent. The seal was able to estimate and then reproduce distances (0.5–18.5 m) with the smallest error below 10% of the actual distance, and its precision was higher with distances repeatedly swum compared to its performance with unfamiliar distances. In the absence of visual cues, the seal’s performance slightly dropped; however, it was still able to perform the task with an error of 21%. In conclusion, distance estimation may help seals to navigate precisely towards their goals, even if, for example, visual information is not available.
