Genetic population structures of fishing resources (abalone, sea cucumber, and sea urchin) off the coast of southern Iwate Prefecture, Japan 2013 Field survey South Sanriku 2013/04/01 - 2014/03/31 Pacific abalone Haliotis discus hannai, Japanese sea cucumber Apostichopus japonicus, and Japanese sea urchin Strongylocentrotus nudus are economically important marine products in Sanriku Coast, Iwate, Japan. Since fishing of the above species is dependent on their natural resources, it is important to examine the influence of the tsunami that hit the Pacific Coast after the Tohoku Earthquake in 2011, on natural marine resources. We assume that the tsunami caused a reduction in the number of individuals in the parental population, which in turn caused a reduction in the genetic diversity. In this study, to monitor the reduction in genetic diversity, which could cause population decline, we compared the genetic population structures of the above three species before and after tsunami using microsatellite (ms) DNA markers.
Studies on the coastal environment and marine resources in the southern part of Iwate Prefecture 2014 Field survey South Sanriku 2014/04/01 - 2015/03/31 1.

Surveys on harmful algae in the coastal areas of southern Iwate Prefecture 2014 Field survey South Sanriku 2014/04/01 - 2015/03/31 Mass culture of shellfish and ascidians has been popular in Sanriku coastal areas maintaining important part of the fisheries there, however paralytic shellfish poisoning (PSP) and diarrhetic shellfish poisoning (DSP) have become great fear against the safe consumption of seafood. PSP and DSP toxins were found to be accumulated to shellfish from the toxic dinoflagellates such as Alexandrium tamarense and Prorocentrum lima respectively. Amnesic shellfish poisoning (ASP) toxin produced by Pseudo-nitzschia multiseries were also found to be the origin of the weekly toxic scallop and blue mussel in Ofunato Bay. Another diatom Nitzschia navis-varingica distributes in brackish areas also has the potential of ASP there. It produces not only domoic acid (DA) but also isodomoic acid B (IB). The Tsunami attacked on March, 2011 along these coastal areas might affect the occurrence of these toxic microalgae. It is important to observe the effect of the disaster on the occurrence of the toxic microalgae for the fisheries there.This study was performed to observe the occurrence of toxic and harmful microalgae and to measure/estimate the PSP, DSP and ASP mainly in Ofunato and Okirai Bay.

Genetic population structures of fishing resources (abalone, sea cucumber, and sea urchin) off the coast of southern Iwate Prefecture, Japan 2015 Others South Sanriku 2015/04/01 - 2016/03/31 Pacific abalone Haliotis discus hannai, Japanese sea cucumber Apostichopus japonicus, and Japanese sea urchin Strongylocentrotus nudus are economically important marine products in Sanriku Coast, Iwate, Japan. Since fishing of the above species is dependent on their natural resources, it is important to examine the influence of the tsunami that hit the Pacific Coast after the Tohoku Earthquake in 2011, on natural marine resources. We assume that the tsunami caused a reduction in the number of individuals in the parental population, which in turn caused a reduction in the genetic diversity. In this study, to monitor the reduction in genetic diversity, which could cause population decline, we will compare the genetic population structures of the above three species before and after tsunami by using microsatellite (ms) DNA markers. This year, we will collect new generation samples to analyze the increase in ms loci from the previous msDNA analysis of the populations. Furthermore, to examine changes in the genetic diversity, we will also analyze the mitochondrial (mt) DNA for these populations.

Survey on harmful algae in the coastal area of southern Iwate Prefecture 2015 Field survey South Sanriku 2015/04/01 - 2016/03/31 In the Sanriku coast, aquaculture such as bivalves have been developed, however, shellfish poison phenomenon associated with the occurrence of toxic micro-algae has become one of the most serious problems. In Ofunato Bay, abundance of cyst of dinoflagellate that cause paralytic shellfish poison increased significantly, and degree of shellfish poison has become a serious problem. On the other hand, amnesic shellfish poisoning (ASP) is caused by domoic acid (DA) generated by Pseudo-nitzschia diatom, cause poisoning by poison accumulates in fish and shellfish through the food chain. P. multiceries, a highly toxic species is distributed around Sanriku coastal area, and scallop and mussels are poisoned by this diatom. The occurrence of these harmful algae is serious problems in fisheries. The present study aimed that to reveal the abundance and distribution of these harmful algal cysts and occurrence and toxicity of ASP diatom.

Dynamics of coastal demersal fishes and evaluation of viability of populations 2014 Others 2014/04/01 - 2015/03/31 Coastal marine organisms have been influenced by global climatic changes irrespective of the effect of earthquake and tsunami. To evaluate the effects of 2011.3.11 earthquake on marine organisms, we need examine the distribution and population changes from several decade ago. In this study, we evaluate the effects of both global climate changes and earthquake by analyzing the population changes using Bottom-trawl survey data. In addition, focusing on Gadus macrocephalus, we developed genome-wide SNP markers and detect the markers relating to environmental adaptation, and using these SNP makers, we develop the method evaluating population viability responding to the environmental changes. MethodWe used captured data from 1993 to 2012 for 7 demersal species, and obtained environmental variable (surface and bottom water temperature, salinity, current) for JCOPE. Then, we estimate the CPUE dynamics of these fishes. In this year, we obtained data for Doto, Okhotsk, Sea of Japan, in addition the Tohoku coast. We used GAM analysis to detect the effect of temperature, salinity,water depth and year on CPUE. We conducted RAD-seq analyais for 234 individuals form 19 population around the coast of Japan. We obtained 12942 SNP markers. Among them 389 to 2563 SNP were effective to use population genetic analysis.

Dynamics of coastal demersal fishes and evaluation of viability of populations 2015 Others 2015/04/01 - 2016/03/31 Coastal marine organisms have been influenced by global climatic changes irrespective of the effect of earthquake and tsunami. To evaluate the effects of 2011.3.11 earthquake on marine organisms, we need examine the distribution and population changes from several decade ago. In this study, we evaluate the effects of both global climate changes and earthquake by analyzing the population changes using Bottom-trawl survey data. In addition, focusing on Gadus macrocephalus, we developed genome-wide SNP markers and detect the markers relating to environmental adaptation, and using these SNP makers, we develop the method evaluating population viability responding to the environmental changes. Method. We used captured data from 1993 to 2012 for 7 demersal species, and obtained environmental variable (surface and bottom water temperature, salinity, current) for JCOPE. Then, we estimate the CPUE dynamics of these fishes. In this year, we analyze these data by using Convergent Cross Mapping method. We conducted RAD-seq analysis for 234 individuals form 19 population around the coast of Japan. We obtained 12942 SNP markers. We try to detect SNP markers related to environmental variables such as sea water temperature. In addition, we examined the relationships between hemoglobin polymorphism and water temperature.

Gonadotropin releasing hormone (GnRH) has been suggested to be useful for manipulation of sex and maturation in some bivalves. In this year, we plan to establish a cell culture system that available for response assessment of GnRH receptor in scallops. Conclusively, we aim to design the general GnRH peptide available for several bivalves to compare responses to the GnRH peptide in these species. We aim to survey a total amount of scallop production and the numbers of facility for scallop farming in Ogatsu Bay for calculation in order to calculate productivity of scallop and compare with a pre-quake period. Additionally, the environmental capacity for scallop culture in Ogatsu Bay was evaluated by growth condition and food availability based on a primary production (i.e., monitoring of chlorophyll a concentration). We plan to evaluate an availability of remote sensing data for estimation of chlorophyll a concentration in waters of Ogatsu Bay comparing with regular line observation and stationary measurement by observation buoy.
