Historical accounts are replete with this productivity, especially when referencing Atlantic Salmon populations. In addition to Atlantic Salmon, Lake Ontario contained a diverse coldwater fish community dominated by Lake Trout, whitefishes (Coregoninae), and Burbot along with rich cool and warmwater fish communities. Lake Ontario also contained marine relict species, such as Harbour Seal, Threespine Stickleback, and possibly Sea Lamprey, Rainbow Smelt and Alewife along with the catadromous American Eel. Following European colonization of the watershed, extensive land-use change, overfishing, dam construction, habitat degradation, pollution, and invasive species all contributed to the decline and extirpation of many native species and shifts in aquatic species communities.

The value of provision services, regulation services, culture services and supporting services accounted for 12.3%, 3.3%, 55.0% and 29.4% of the total value, respectively. Recreation value of culture services had the highest proportion (54.4%), which indicated that recreation service was the crucial role of the coastal wetland in Qinhuangdao.

The responses of stream fish to conductivity remain unclear and strategies for protection are poorly developed. We collected data of fish and conductivity from sixty-two sites of the Taizi River to evaluate the changes to the fish community and species along the gradient of conductivity. Our results found that conductivity elevation was related to the regional development of urban and farmland and the local degradation of habitat quality. The community metrics of abundance and F-IBI, but not species richness and diversity, showed a significant linear correlation with conductivity. Conductivity of the top three F-IBI grades (excellent, good and normal) was significantly lower than those of the other two F-IBI grades (poor and bad). The boundary conductivity between normal grade and poor grade was approximately equal to 500 μS cm−1. We found different probability patterns for different species along the conductivity gradient; one capture probability pattern showed decline trend along the conductivity gradient. Except for two dominating and widespread species and one tolerant species, the remaining fish species of the first pattern should be designated as protection objects. In order to protect fish community integrity and sensitive species, sustainable land use management on the catchment scale and habitat quality improvement on the local scale should be given more attention by catchment managers.","PeriodicalId":8125,"journal":{"name":"Aquatic Ecosystem Health & Management","volume":"22 1","pages":"171 - 182"},"PeriodicalIF":0.8,"publicationDate":"2019-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/14634988.2019.1622994","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49166257","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Eleven beaches showed erosion, while three beaches showed slight accretion. Over the period of measurement nine hurricanes passed close enough to Anguilla to significantly impact the beaches. Analysis of a ten year (2008–2017) record of marine monitoring of fish, marine plants, corals, algae and other invertebrates at 15 sites around Anguilla has shown an 11% drop in coral cover and a 10% increase in algae cover. This contributed to a post Hurricane Luis marine monitoring survey in 1996, which illustrated the dramatic mortality of Anguilla's reef ecosystem that began in the late 1970s with the emergence of white-band disease and continues to this day. An analysis of the changes at each beach shows multiple causal factors including geomorphological adjustments, high swell wave events and hurricanes, hard and soft coastal protection measures, sea level rise and the decline in overall reef heath. Relative importance of each of these factors varied from beach to beach and contributed to the variations in the amount and direction of change at the different locations. The analysis highlights the need to focus on beach and coral reef conservation measures and legislative changes in order for tourism and the economy of Anguilla to thrive.","PeriodicalId":8125,"journal":{"name":"Aquatic Ecosystem Health & Management","volume":"22 1","pages":"193 - 204"},"PeriodicalIF":0.8,"publicationDate":"2019-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/14634988.2019.1628585","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41432576","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Alternatively, non-permanent barriers using electricity, light, sound, pressure, bubbles, and CO2 are being developed and deployed in efforts to limit and prevent the spread of aquatic invasive species or to achieve fish guidance and conservation. However, the effectiveness of these barriers is quite variable and testing is often lacking for both invasive and native species. We conducted a laboratory experiment to investigate the impact of vertical electric barrier on behaviour of Rainbow Trout, Oncorhynchus mykiss. In response to electric current, Rainbow Trout responded by significantly decreasing passage through the electric barrier zone and spending more time away from the electric barrier when it was turned on during the stimulus period compared to pre-stimulus period. Moreover, when interacting with electric barrier, Rainbow Trout exhibited certain behaviours (e.g. stunned and remained on the same side of the barrier, stunned and crossed the barrier) more than others (e.g. approach and retreat, deflected, and paralyzed). Moreover, it appears that Rainbow Trout remained distant from the electric barrier even after the electric barrier was turned off. Our results indicate that relatively weak electric gradient (i.e. voltage gradient: 0.2 – 0.4 v·cm−1, power density: 3 – 42 µW·cm−3) can inhibit the movement of Rainbow Trout. Our results also highlight the importance of detailed investigation of behavioural responses of target species when evaluating and considering fish-deterrent or guidance technologies.","PeriodicalId":8125,"journal":{"name":"Aquatic Ecosystem Health & Management","volume":"22 1","pages":"183 - 192"},"PeriodicalIF":0.8,"publicationDate":"2019-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/14634988.2019.1624135","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48175331","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The combination of observation and simulation in this paper gives a good description on the tidal dynamic system in Daya Bay. As indicated by model results, the tidal current velocity in the Bay totally decreases after numerous activities associated with reclamation construction. The decreasing current velocity region is mainly distributed near the Xiachong and Gangkou chain islands. The current velocity in 2015 decreases by approximately 5 cm s−1 compared with velocities before 2000. Future reclamation activities will exacerbate these decreasing current velocity trends in some regions. Compared with 2015, the tidal prism has significantly decreased by 1.3622 × 107 m3 due to planned reclamation. The half-water exchange times for Daya Bay in 2015 and after planned reclamation are 178.9 and 177.4 days, respectively.

The dinoflagellate Noctiluca scintillans is one dominat alga in the Sea of Oman, whereas diatom species are more common in the Arabian Gulf blooms. In general, the phytoplankton and zooplankton species diversity during winter was higher than in summer periods. Catches of small pelagic fish (in particular sardines) in the Sea of Oman exceeded that in the Arabian Gulf. This might be associated, in part, with differences in trophic levels interactions.
