Resumen en inglés

The Mayan octopus, Octopus maya, fishery from the Campeche Bank is the largest octopus fishery in the Americas and one of the largest worldwide. This fishery uses a large quantity of crabs, Brachyura, as bait, and these crustacean populations are heavily impacted. To investigate alternative lures we examined the efficacy of various artificial lures ranging from plastic crabs to jigs baited with fish during the 2012 and 2013 seasons. Artificial PVC “crab” lures showed the best yields. However, their performance was less effective than natural crab in all cases. A simple simulation showed that using these lures, harvests would decrease by 42–44% compared to using natural crab. We suggest the use of PVC crab combined with an organic compound that releases an attractive scent for octopus in further experiments.

Resumen en español

Octopus hubbsorumes la principal especie de pulpo capturada en el Pacifico mexicano, sin embargo, aún no cuenta con regulación pesquera. Santa Rosalía en Baja California Sur, es el puerto donde se registran los mayores desembarques anuales de pulpo. Las muestras mensuales provinieron de la captura comercial de septiembre del 2014 a agosto del 2015 en el corredor pesquero Santa Rosalía Punta Chivato. Se analizaron un total de 202 organismos cuyo rango de longitud dorsal del manto (LDM) fue 50-170 mm con un promedio y moda de 110 mm, mientras que, el peso total (PT) fluctuó entre los 150 y 1900 g con un promedio de 695 g y moda de 500 g, se les evaluaron algunos de los principales parámetros biológicos como la proporción sexual, ciclo reproductivo, época reproductiva, tallay peso a la madurez, condición durante la maduración gonádica, además de la interacción de la temperatura superficial del mar (TSM) con la actividad reproductiva. En la muestra total (0.6H:1M) y en agosto (0.22H:1M) y octubre (0.25H:1M) hubo significativamente más machos que hembras. El principal evento reproductivo de las hembras ocurre en junio-julio, coincidente con el máximo valor de TSM(30°C). En tanto que, la actividad reproductiva de los machos fue continuaa lo largo del año. El patrón ovárico fue sincrónico de acuerdo conla distribución del área proporcional de los ovocitos. De los tres índices reproductivos utilizados en este estudio, el IGS fue el que más se aproximó a identificar el estadio maduro y consecuentemente la actividad reproductiva, definida previamente por el análisis microscópico.

El índice de condición de las hembras no tuvo una tendencia clara con respecto a la maduración gonádica, lo que hace suponer que la energía para el desarrollo de la gónada no proviene principalmente de las reservas de la glándula digestiva. La talla y peso a la madurez de las hembras fue de 130 mm LDMy 960 g de peso total (PT), respectivamente. Mientras que, los machos presentaron signos de madurez a 100 mm LDM y 600 g PT. Se evaluaron los rasgos reproductivos y la estrategia de patrón de desove de O. hubbsorum, aportando información básica para un futuro manejo de la especie principal de pulpo del Pacífico mexicano.

Resumen en inglés

Octopus hubbsorum is the main species of octopus captured in western Mexico and Santa Rosalía is the port that generates the largest annual landings of octopus from all Baja California Sur (BCS). Based on commercial captures, a monthly sampling was carried out from September 2014 to August 2015 in the Santa Rosalía Punta Chivato fishing corridor. The 202 sampled octopuses ranged from 50 to 170 mm in mantle length (ML) and 150 to 1900 g in body weight (BW). We evaluated main biological parameters, sex ratio, reproductive event, reproductive indices, size and weightat maturity and condition. The total gender ratio was significantly different from 1:1 (0.6 H: 1m), however the monthly ratio was only significant in August and October. Mature males were found all year round and ovarian development was synchronous as part of their reproductive strategy.

The main reproductive peak occurs in June-July when the surface temperature of the sea reaches 30 ° C and the secondary peak in March-April at 20.7 °C. Based on the three indirect reproductive indices used in this study the IGS was the most appropriate to determine the stages of maturity previously defined by the microscopic analysis. According to the condition index, females apparently support the gonadic maturation of most of the diet. The size and weight at maturity of females was 130 mm LDM and 960 g PT, respectively and 100 mm and 600 g for males. The reproductive traits and reproductive strategy of O. hubbsorum was evaluatedto provide basic information for future management.

The common octopus of the Veracruz Reef System (VRS, southwestern Gulf of Mexico) has historically been considered as Octopus vulgaris, and yet, to date, no study including both morphological and genetic data has tested that assumption. To assess this matter, 52 octopuses were sampled in different reefs within the VRS to determine the taxonomic identity of this commercially valuable species using an integrative taxonomic approach through both morphological and genetic analyses. Morphological and genetic data confirmed that the common octopus of the VRS is not O. vulgarisand determined that it is, in fact, the recently described O. insularis. Morphological measurements, counts, indices, and other characteristics such as specific colour patterns, closely matched what had been reported for O. insularis in Brazil. In addition, sequences from cytochrome oxidase I (COI) and 16S ribosomal RNA (r16S) mitochondrial genes confirmed that the common octopus from the VRS is in the same highly supported clade as O. insularisfrom Brazil. Genetic distances of both mitochondrial genes as well as of cytochrome oxidase subunit III (COIII) and novel nuclear rhodopsin sequences for the species, also confirmed this finding (0–0.8%). We discuss our findings in the light of the recent reports of octopus species misidentifications involving the members of the ‘O. vulgaris species complex’ and underscore the need for more morphological studies regarding this group to properly address the management of these commercially valuable and similar taxa.

Resumen en inglés

Largely shell-less relatives of clams and snails, the marine mollusks in the class Cephalopoda--Greek for "head-foot"--are colorful creatures of many-armed dexterity, often inky self-defense, and highly evolved cognition. They are capable of learning, of retaining information--and of rapid decision-making to avoid predators and find prey. They have eyes and senses rivaling those of vertebrates like birds and fishes, they morph texture and body shape, and they change color faster than a chameleon. In short, they captivate us. From the long-armed mimic octopus--able to imitate the appearance of swimming flounders and soles--to the aptly named flamboyant cuttlefish, whose undulating waves of color rival the graphic displays of any LCD screen, there are more than seven hundred species of cephalopod. Featuring a selection of species profiles, Octopus, Squid, and Cuttlefish reveals the evolution, anatomy, life history, behaviors, and relationships of these spellbinding animals. Their existence proves that intelligence can develop in very different ways: not only are cephalopods unusually large-brained invertebrates, they also carry two-thirds of their neurons in their arms. A treasure trove of scientific fact and visual explanation, this worldwide illustrated guide to cephalopods offers a comprehensive review of these fascinating and mysterious underwater invertebrates--from the lone hunting of the octopus, to the social squid, and the prismatic skin signaling of the cuttlefish.

Mexican management plans currently consider just two octopus species in the official regulations, Octopus maya and Octopus vulgaris. However, the common octopus of the southwestern Gulf of Mexico has been recently identified as Octopus insularis, a species with unique biological and ecological characteristics. In accordance, we sampled O. insularis artisanal catches from the marine protected area of the Veracruz Reef System (VRS) between November 2017 and October 2018 and described its population structure and reproductive dynamics to provide basic biological information for the sustainable management of the species in the region. The 1,007 sampled octopuses ranged from 48 to 2,063 g in body weight (BW) and from 26 to 163 mm mantle length (ML). Most males were mature while the majority of females were immature. Although fishing closures in January, February and August precluded data gathering, most mature and juvenile specimens were registered in March and June respectively, thus, suggesting a year-long life cycle with spawning and recruitment peaks during winter and summer months respectively. Overall, sex ratios did not significantly shift from the expected 1:1, however males were significantly more abundant in December, which could be related to female spawning migrations to deeper waters. This was also supported by the generalized scarcity of mature and spent females in the catches. Males mature at a smaller size (590 g BW; 90 mm ML) than females (870 g BW; 108 mm ML). Although size at maturity is lower than the current minimum legal size for both sexes, most of sampled octopuses were smaller anyway, raising concern about the future sustainability of the fishery.

Resumen en inglés

High plasticity in cephalopod populations shows dramatic changes in their biological traits. Commercial catches of Mayan octopus (Octopus maya) in six localities of the state of Campeche, Mexico, were sampled monthly for five consecutive fishing seasons (2005–2009) in order to describe variations in population structure and maturation. Octopus maya grows and matures during the fishing season, from August to December. Spent individuals predominate in January and February, revealing a year-long life cycle. However, the presence of a few spent females in all months sampled suggests that a small part of the population shows an extended spawning period. Overall sex ratios did not significantly shift from the expected 1:1 in most samples. Males are mostly mature while the majority of females are immature during the season. Use of illegal fishing gears (spear diving or pots) in central localities accounts for a larger share in mature females. Octopus size showed large interannual and geographic differences. Females mature at a larger size (1024 g body weight, BW; 124 mm mantle length, ML) than males (484 g BW; 91 mm ML). Size at maturity in both sexes varies more between seasons than between localities. Female ML at maturity is larger than the current minimum legal size and implications for current octopus fishing regulations are discussed.

The geographic distribution of Octopus mimus Gould, 1852 is unclear, as most records are restricted to coastal localities of Peru and Chile, and some references have mentioned its presence off Central America. It is unknown whether this octopus is found off Ecuador as two previous unpublished records have suggested. The aim of the present study is to identify genetically the main octopus captured in a marine protected area known as Reserva de Produccion Faunistica Marino-Costera Puntilla de Santa Elena (REMACOPSE) off the Santa Elena peninsula, Ecuador. Samples collected from the local fishery were used to test the presence of this species based on the sequences of three mitochondrial markers and using a Bayesian approach. The phylogenetic analysis confirms that O. mimus inhabits the REMACOPSE. The results also indicate that the octopus specimens captured in the fishery from this marine protected area, are more closely related to O. mimus specimens from Central America than those from South America. The genetic identification of two groups of O. mimus could be associated with the different marine environmental conditions of the two biogeographic provinces. The finding in this study represents an important step for posterior research on the biology and fishery of octopus in Ecuador.

Resumen en inglés

The genus Octopus occurs in tropical and temperate oceanic waters throughout the world, and currently includes 112 species, although the phylogenetic relationships among the different taxa are still poorly understood. The cosmopolitan Octopus vulgaris is one of the most widely analyzed cephalopods in genetic studies, primarily because of its ample range and the problems associated with the morphological identification of specimens, which indicate the possible existence of a species complex with a worldwide distribution. Two large-bodied octopus species—O. vulgaris and Octopus insularis—are found in the western South Atlantic. The limits of the geographical range of the O. insularis are still unclear. The current study is based on a phylogeographic analysis of the 2 species in the South Atlantic, with the objective of confirming their monophyletic status and the limits of their geographical distribution in this region. The analyses were based on the mitochondrial genes 16S rDNA and Cytochrome Oxidase subunit I (COI). The topologies generated for both genes confirmed the monophyletíc status of the 2 species. In the case of O. vulgaris, it was possible to confirm the monophyletic status of the specimens from this region relative to those of other areas around the world, although 3 distinct haplogroups were clearly differentiated, corresponding to the Americas, Europe and Africa, and Asia. The differentiation among these 3 groups may be determined by the limitations of the dispersal of paralarvae among continents. Further studies are needed to confirm the possible occurrence of distinct groups in the western South Atlantic, as well as the influence of oceanic currents on the phylogeographical distribution of O. vulgaris on the Brazilian coast.
