“…According to the China fishery statistical yearbook (Zhao 2016), cephalopod landings totalled nearly 0.7 million tonnes in 2015, with an increase of 3.42% over the previous year. Because of the high economic benefits surrounding octopods, many intensive studies have investigated their population genetics (Zheng et al 2009, Meriam et al 2015, Gao et al 2016), behaviour (Meisel et al 2013, Polese et al 2015, Levy et al 2015, Richter et al 2016), neurology (Nixon and Young 2004, Zarrella et al 2015), and reproductive biology (Wada et al 2006, Ebisawa et al 2011, Wang et al 2015b). However, while significant genetic knowledge is required for effective breeding and aquaculture of octopods, modern cytogenetic studies of these species are scarce.…”

Karyotype analysis was carried out on gill cells of three species of octopods using a conventional air-drying method. The karyotype results showed that all the three species have the same diploid chromosome number, 2n=60, but with different karyograms as 2n=38M+6SM+8ST+8T, FN (fundamental number)=104 (Cistopus chinensis Zheng et al., 2012), 2n=42M+6SM+4ST+8T, FN=108 (Octopus minor (Sasaki, 1920)) and 2n=32M+16SM+12T, FN=108 (Amphioctopus fangsiao (d’Orbigny, 1839–1841)). These findings were combined with data from earlier studies to infer the genetic relationships between nine species via cluster analysis using the karyotype evolutionary distance (De) and resemblance-near coefficient (λ). The resulting tree revealed a clear distinction between different families and orders which was substantially consistent with molecular phylogenies. The smallest intraspecific evolutionary distance (De=0.2013, 0.2399) and largest resemblance-near coefficient (λ=0.8184, 0.7871) appeared between O. minor and C. chinensis, and Sepia esculenta Hoyle, 1885 and S. lycidas Gray, 1849, respectively, indicating that these species have the closest relationship. The largest evolutionary gap appeared between species with complicated karyotypes and species with simple karyotypes. Cluster analysis of De and λ provides information to supplement traditional taxonomy and molecular systematics, and it would serve as an important auxiliary for routine phylogenetic study.

“…Earlier several studies were under taken including complete mitochondrial genome of this species (Cheng et al 2012). Previous investigations on population genetics of O. minor present subtle to significant differences (Gao et al 2016; Yang et al 2015; Lü et al 2013; Kang et al 2012; Xu et al 2011; Sun et al 2010; Li et al 2010). Our present analysis of two nuclear DNA gene sequences in O. minor collected from eight locations imparted variation.…”

“…The basic information of genetic variation and population structure is valuable for stocking, fisheries management, and conservation (Feng et al 2017). Several divergent forces cause genetic differentiation, including geographic isolation, current and life history characteristics (Gao et al 2016). In fact, oceanic processes are complex and a single reason cannot be claimed as source of divergent force.…”

“…In fact, oceanic processes are complex and a single reason cannot be claimed as source of divergent force. There are many islands and gulfs in China’s sea, which can contribute to the gene flow complications of the populations (Gao et al 2016). Earlier several studies were under taken including complete mitochondrial genome of this species (Cheng et al 2012).…”

Octopus minor is an economically important resource commonly found in Chinese coastal waters. The nuclear gene (RD and ODH) approach of investigation has not reported in this species. Rhodopsin (RD) and octopine dehydrogenase (ODH) genes were used to elaborate the genetic structure collected from eight localities ranging from the northern to the southern coast of China. In total, 118 individuals for the RD gene and 108 for the ODH were sequenced. Overall (RD and ODH) genes resulted in high (0.741±0.032; 0.805±0.038) haplotype and low nucleotide (0.01261±0.00165; 0.00747±0.00086) diversity. Molecular variance displayed higher values among the populations and lower values within the population where the fixation index FST denoted 0.880 and 0.584 in RD and ODH genes respectively. The Dongshan population clustered separately in a phylogenetic tree as in the haplotype networking assessment. The current data suggests that the Dongshan population needs separate management.

Octopus mimus es una especie de importancia pesquera que se distribuye a lo largo del litoral del Pacífico oriental. Con base en datos moleculares se ha evidenciado que su rango geográfico comprende desde el golfo de California y América Central hasta el norte de Chile. Asimismo, se ha reportado que O. mimus presenta baja diversidad y estructura genética debido principalmente a sus fluctuaciones demográficas, a su historia de vida y a la presión selectiva en el Pacífico oriental.Sin embargo, la estructura genética y los procesos evolutivos que influyen en el patrón filogeográfico de O. mimus no han sido revisados mediante marcadores hipervariables. Con la finalidad de evidenciar la estructura genética en O. mimus y sus relaciones filogeográficas en su distribución, en el presente estudio fueron utilizados marcadores microsatélites y la obtención de los resultados fue planteada con relación a tres niveles de resolución para validar la conformación de los dos grupos biogeográficos de O. mimus previamente identificados por otros autores.Los resultados obtenidos en el presente trabajo permitieron confirmar la baja estructura genética pero significativa (P < 0.05) de O. mimus, y se confirmaron los dos grupos biogeográficos (panámico y peruano) de la especie. El promedio de la diversidad genética de O. mimus fue alta con relación a la heterocigosidad observada y la esperada (Ho = 0.714, He = 0.619) y los análisis demográficos, con base en la prueba de Wilcoxon (P < 0.05) y la distribución de las frecuencias alélicas, indicaron la ausencia de cuellos de botella recientes. La construcción de un dendrograma permitió soportar la agrupación poblacional de O. mimus respecto a los dos grupos genéticos que conforman a la especie. La información obtenida será relevante para desarrollar posteriormente estrategias de conservación y un plan de manejo pesquero para O. mimus.
