This work is an updated checklist of Mexican Pycnogonida species for both oceans, the Mexican Pacific (PA) and the Gulf of Mexico (GMx). This research was carried out based on the first historical records by Schimkewitsch in 1893 up to the present day. The number of recorded species increased in this study. The total number of species in Mexican oceans is 58, distributed among 19 genera and 10 families. All records were cross-referenced with the original literature, and those found to be questionable were deleted from the checklist. With the data reported in this checklist, an extrapolation of the total number of species was performed using rarefaction curves, thus demonstrating that the recorded species fell well below the projected diversity. The curves showed an estimate of 80 species in the Pacific, whilst 100 species were projected for the Gulf of Mexico. These data indicate that collection efforts and species occurrences nationwide and by waterbody (PA and GMx) are insufficient to describe the diversity of Mexican pycnogonids.

The banco de las Ánimas is a poor studied underwater environment with a characteristic reef fauna and an unknown large number of cryptic species. Annelids are one of the most common invertebrate groups in the coral formations of the Colombian Caribbean; these organisms are very abundant and variable in their body shapes (parapodia, setae, and gill structures), which imply a great evolutionary radiation. In order to know the diversity of annelids in the reef ecosystem in the Banco de las Ánimas, four artificial structures (known as autonomous reef monitoring structures) used as fauna collectors were located at a depth of 14 m in the Montículo sector. The first records for the Colombian Caribbean of 23 species of annelids of the families Amphinomidae, Eunicidae, Polynoidae, Lumbrineridae, Sabellidae, Serpulidae, Sigalionidae, Syllidae, and Terebellidae. The contribution to the knowledge of the fauna of reef annelids of a little poor known area of the Colombian Caribbean is highlighted.
banco de las Ánimas是一个研究较少的水下环境，具有独特的珊瑚礁动物群和未知的大量隐物种。环节动物是哥伦比亚加勒比海珊瑚群中最常见的无脊椎动物之一;这些生物数量非常丰富，在它们的身体形状(副足、刚毛和鳃结构)上变化很大，这意味着一个巨大的进化辐射。为了了解Banco de las Ánimas珊瑚礁生态系统中环节动物的多样性，在Montículo区域的14米深处放置了四个人工结构(称为自主珊瑚礁监测结构)作为动物收集器。哥伦比亚加勒比海地区首次记录了23种节肢动物，分别为:双翅虫科、蠓科、多翅虫科、蚓虫科、沙贝类科、刺贝类科、刺贝类科和刺贝类科。强调了对哥伦比亚加勒比海鲜为人知的珊瑚礁环节动物动物群知识的贡献。

The performance of the winged pearl oyster Pteria colymbus juveniles under suspended culture conditions was evaluate, including five culture methods and two seasons: upwelling and non-upwelling. Culture methods comprised enclosures confining the oysters: BTBC, BBOand BTO; and two other unconfined-oyster: OFOB and FNS. The initial shell height of the oysters ranged between 31–35 mm in both seasons. The increase in shell size and dry mass of soft tissues showed significant differences between seasons. Greatest growth occurred with the OFOB and FNS unconfined methods. The ANOVA II analysis showed significant differences between the variables obtained in both stations and culture methods. Principal Component Analysis showed that the interactions between the variables: temperature (inverse relationship), and UI, chl-a and POM (direct relationship) explained 89 % of the variability of the growth of the oysters. Given the low survival rates, attributed to the presence of predators within the closed enclosures and the higher growth seen in the culture methods without confinement, we recommend using the FNS and OFOB methods, taking advantage of the byssus produced by P. colymbus.

Morphological identifications complemented with molecular analysis are important for the delimitation of cryptic species. This document contains annotations on the molecular identification of the parasitic nemertine Carcinonemertes conanobrieni in the Caribbean spiny lobsters Panulirus argus. The collected nemerteans were found parasitizing ovigerous lobsters from the Gulf of Salamanca (Puebloviejo), Colombia. DNA was extracted from a specimen and a fragment of the mitochondrial gene Cytochrome Oxidase I (COI) was amplified using Folmer’s universal primers, the sequence was edited with ProSeq 3.5 and aligned with all the C. conanobrienisequences available in GenBank. A sequence of 488 base pairs corresponding to the section of the genetic barcode of the COI gene was obtained, the matrix of genetic distances showed little variation when comparing the obtained sequence with those available in the GenBank database. These results confirm the presence of this nemertean in the Panulirus argus lobsters in Colombia providing valuable information for the correct identification and detection of this parasitic species in the country, thus facilitating its monitoring
形态学鉴定与分子分析相结合对隐种的划分具有重要意义。本文对加勒比大螯虾(Panulirus argus)中寄生nemertine Carcinonemertes conanobrieni的分子鉴定作了注释。收集到的nemerteans寄生在哥伦比亚萨拉曼卡湾(Puebloviejo)的产卵龙虾上。从标本中提取DNA，使用Folmer通用引物扩增线粒体基因细胞色素氧化酶I (Cytochrome Oxidase I, COI)片段，使用ProSeq 3.5编辑该序列，并与GenBank中提供的所有C. conanobrienisence序列比对。获得了COI基因遗传条形码片段对应的488个碱基对序列，与GenBank数据库中的遗传距离矩阵差异不大。这些结果证实，在哥伦比亚的阿格斯龙虾中存在这种寄生虫，为正确识别和检测该国的这种寄生虫物种提供了有价值的信息，从而促进了对其的监测

The Spanish sardine Sardinella aurita, is the most important fishing resource in Venezuela, on Margarita Island it began its fishing and canning. This review estimates catch over nine decades and causes of fishing continuity. In 90 years, 4,386,758 tons were caught, a modest volume due to poor statistics. Three management ordinances have been enacted the first appeared after 40 years of activity in canning plants. The sardine industry has four periods, the first between 1927 and 1973 without fishing regulation and another three (1974-2005; 2006-2013 and 2014-2017) when the ordinances are applied. In each one the catch, annual average, operating gears, the capture per unit of effort and relevant investigations are considerate. The current regulation was based on the noticeable decrease in catches since 2005, which is why, in 2013, a ban was imposed and the minimum catch size was established at 19 cm. The regulation is ineffective because after seven years, the catches do not recover previous levels, in addition, it is incomprehensible to increase fishing gear (357 fishing in 2017). The artisanal fishing with beach seine (chinchorro) and the average maturity size of the species explain the permanence of the fishery, which endangered by the intensive use of purse seines that must be restricted.

Para contrarrestar la propagación de la enfermedad pandémica del Covid-19, el gobierno de Colombia decretó un periodo de cuarentena de marzo 24 a julio 1 de 2020, que obligó al cese de las actividades turísticas y al cierre de los principales destinos turísticos del Caribe colombiano: Santa Marta, Cartagena y San Andrés. Durante este periodo se percibió un incremento significativo en la calidad ambiental de estas zonas costeras. Para cuantificar los cambios ambientales en la zona costera, se analizó la variación en la concentración de la clorofila y los sólidos suspendidos totales de la misión satelital Sentinel-3, 30 días antes y después del inicio de la cuarentena. Los resultados mostraron una disminución en la concentración de clorofila (> 20 %) y sólidos suspendidos (> 40 %) frente a Santa Marta y Cartagena, pero ningún cambio significativo en San Andrés. Aunque parte de esta reducción estuvo vinculada a cambios estacionales en forzantes locales, los resultados sugieren que la recuperación ambiental podría ser un efecto remoto del cese de actividades contaminantes en el territorio continental. Así, la cuarentena Covid-19 proporciona un referente para observar efectos de las actividades productivas y turísticas, potencialmente útil para establecer la capacidad de carga y recuperación de ecosistemas costeros.

Good knowledge of the coastal circulation patterns is essential for a proper management of the coastline, especially in areas with a high anthropic pressure. In order to determine the main characteristics of the coastal currents in the Gulf of Uraba, the seasonalpatterns of surface circulation were measured and analyzed during times of high and low rainfall along 6 km of coastline, between the Punta de Las Vacas and Punta Yarumal coastal spit systems, in the municipality of Turbo, Antioquia. These measurements were made with surface drifters, which were launched at different tide stages and tracked for time periods based on the semi-diurnal cycle. The in-situ measurements were analyzed alongside tide and wind data from a climatic station located near the gulf. The circulation patterns behaved differently depending on the season of the year. In the rainy season, with southerly winds, the drifters moved mainly towards the north while during the dry season, with northerly winds, all the drifters moved to the south. Although the circulation patterns showed a strong relationship with the tidal cycle and wind conditions, the Turbo and El Uno Bays modified some of the drifter’s paths.

Se describen los procesos de conservación y ecología de anidación de la tortuga carey (Eretmochelys imbricata), producto del monitoreo sistemático entre 2018 y 2019 en el corregimiento de Rincón del Mar, San Onofre, Sucre. Se registraron seis nidadas de tortuga carey, todos fueron dejadas in situ y un nido fue saqueado por humanos. Las hembras desovaron un total de 761 huevos en cinco nidadas (promedio ± DE: 152,2 ± 15,5 huevos por nidada). El éxito de eclosión fue en promedio 78,2 ± 12,4 % y el éxito de emergencia fue en promedio 74,7 ± 14,1 % (n = 5). El periodo de incubación fue en promedio de 54 ± 7,8 días (n = 4). Fueron liberadas 591 crías al mar, de las cuales 22 (3,72 %), fueron rescatadas y liberadas con la comunidad. Además, se realizaron mediciones físicas de los nidos (ancho, profundidad, distancia a la playa), medidas morfométricas de los neonatos (ARC, LRC y peso) y se identificaron amenazas en el sector. Nuestros resultados contribuyen al conocimiento del estado actual de la tortuga carey, así como lo indispensable de la participación comunitaria para su conservación en Rincón del Mar.
