Cormorants are blamed for decreased fish catches in many lakes in Poland. The aim of this paper is to describe to role of pikeperch (Sander lucioperca) in the diet of cormorants nesting in a colony on the island in Lake Warnołty. Since the breeding colony is located in the vicinity of Lake OEniardwy, the largest lake in Poland, the cormorants use the resources in this lake. In 2009-2016, 18,432 regurgitated fish were collected, of which 593 were pikeperch. The share of pikeperch among fish collected in 2009-2012 did not exceed 2%, but from 2013 this increased substantially to maximum of 38.2% in 2015. The smallest pikeperch had a standard length of 8.4 cm, and the largest 42.5 cm. Pikeperch mean length differed by year, and the length distribution was close to normal. The sizes of the regurgitated pikeperch indicate that cormorants prey almost exclusively on juvenile specimens. The results of the present study indicate that cormorant predation has a significant impact on pikeperch populations in lakes in the vicinity of the colony, and the great cormorants are possibly a significant factor in the effectiveness of pikeperch management. When planning for the management of fish populations in lakes subjected to cormorant predation pressure, it should be borne in mind that predation by this piscivorous bird species impacts the abundance and size-age structure of fish populations.","PeriodicalId":8293,"journal":{"name":"Archives of Polish Fisheries","volume":"54 1","pages":"123 - 130"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89941847","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

(mean body weight – 78.33 g) of the intraperitoneal implantation of telemetry transmitters using different suturing methods. In the first experiment silk sutures were used (experiment I – group ST), while in the second tissue adhesive was used (experiment II – group GT). Following the procedure, the fish were kept for 42 days in a recirculating system. Differences in growth and condition parameters were only noted in the first week of the experiment. Specimens from group GT had lower values for DGR (daily growth rate) and SGR (specific growth rate), but a higher value for FCR (feed conversion ratio) values. For the hematological parameters, lower values of MCV (mean corpuscular volume) and PLT (blood platelets) were noted in group GT, while for the biochemical parameters, lowered ALP (alkaline phosphatase) activity and Mg (magnesium) concentrations were noted in group ST. In group ST, 33.3% of the specimens loss their tags, while in group GT 77.8% did so. Differences in incision healing were only noted in the second week, when specimens in group ST were observed to have fully closed incisions, while in group GT 50% of the incisions were open. Despite the high percentage of implantation incision healing in both groups, because of the high values of tag loss rate, neither method can be recommended for perch. It might be more effective to use tag with external antennae in this species. The method use for closing implantation incisions also must be improved to eliminate tag shedding.","PeriodicalId":8293,"journal":{"name":"Archives of Polish Fisheries","volume":"108 1","pages":"101 - 89"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76232806","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Univariate analysis indicated that the relative length of anterior margin of radii played a significant role in the separation of some species studied (P < 0.05). Canonical Variates Analysis (CVA) based on seven landmarks showed clear separation between the Iranian inland and inland-related Aphanius species (IIRAS) group (four species) and the brackish water species (A. dispar). The lepidonts were conical in the IIRAS group with the exception of A. isfahanensis (rounded) and were rounded in A. dispar. Based on the basal position of the brackish water Aphanius species in the phylogenetic trees of the genus Aphanius, it can be assumed that the presence of rounded lepidonts was a primary state in their scales or is the result of convergent evolution. Also, the polygonal state in the scales of Aphanius species was a primitive shared character state.","PeriodicalId":8293,"journal":{"name":"Archives of Polish Fisheries","volume":"1 1","pages":"77 - 87"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87402174","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

After three days of immersion, survival, leukocyte (WBC), erythrocyte (RBC), hemoglobin (Hb), hematocrit (Hct), platelet (PLT), and differential leukocyte counts were compared between the two groups. Surviving fish from each group were then divided into three subgroups: subgroup without injection; subgroup injected with normal saline; subgroup injected with Aeromonas hydrophila. Survival, WBC, RBC, Hb, Hct, PLT, the percentage and number of lymphocyte, monocyte, and granulocytes post injection were evaluated for 48 h. The results showed that the survival of immersed fish was significantly higher than that in the control. No significant differences in the hematological profile were noted between the control and the immersed fish. The WBC of control subgroup (A. hydrophila injection) was significantly increased after 24 h. The fish immersed and injected with A. hydrophila had the highest PLT. The number of lymphocytes of all subgroups of fish was stable while the percentage of monocytes and granulocytes of the subgroups of immersed fish were increased.

However, there is no data about the oxidative status of fish oocytes once released into water. This study aimed to investigate the effects of polluted (Soummam River) and unpolluted (Agrioun River) fresh water on the oxidative biomarkers of Barbus callensis (=Lucibarbus callensis) (Val.) oocytes. The experimental design consisted of collecting fish oocytes from polluted and unpolluted rivers and then activating these oocytes separately in water collected from each site. Four groups were considered: oocytes from the Agrioun River activated in Agrioun fresh water (A-oocytes/A-fresh water); oocytes from the Agrioun River activated in Soummam fresh water (A-oocytes/S-fresh water); oocytes from the Soummam River activated in Agrioun fresh water (S-oocytes/A-fresh water); and oocytes from the Soummam River activated in Soummam fresh water (S-oocytes/S-fresh water). Oxidative stress biomarkers were evaluated by measuring total antioxidant status (TAS), catalase (CAT) activity, and cell-free hemoglobin (Hb) concentrations. The results showed that the oxidative status of fish oocytes was significantly affected by the quality of fresh water. Unpolluted fresh water improved the antioxidant activity of the fish oocytes. The results of this study suggest that once oocytes are released into polluted water, antioxidant protection is affected with subsequent cellular oxidative damage and potential reproduction impairment.","PeriodicalId":8293,"journal":{"name":"Archives of Polish Fisheries","volume":"44 1","pages":"11 - 19"},"PeriodicalIF":0.0,"publicationDate":"2017-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76335281","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The formalin detected was 12.19 ±0.814 μg g-1 for freshly treated samples and 8.10 ± 0.068 μg g-1 for treated samples stored on ice. In the control fish, the formalin concentration was almost negligible. The assessment of the organoleptic characteristics of the treated fish revealed that the gills had blackened, the eyes had become whitish and opaque, the muscles had lost tenderness, and the fish had stiffened. The quality assessment score of the control batch was significantly higher than that of the treated batch. The microbes in the fish were still lower than the amount specified for fish spoilage. Lipid hydrolysis in the treated fish was much higher than that of control, especially when storage time increased. High levels of trichloroacetic acid (TCA) soluble protein in the treated fish, as compared to that of the control fish, were observed throughout the storage period. Considering the low organoleptic status and poor nutritional quality, formalin treatment in the fish industry is not recommended even though the formalin content and the microbiological counts were still below permissible limits.","PeriodicalId":8293,"journal":{"name":"Archives of Polish Fisheries","volume":"1 1","pages":"43 - 50"},"PeriodicalIF":0.0,"publicationDate":"2017-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88867965","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study was conducted on Lake Dobrąg located in the Warmian-Masurian Voivodeship (surface area - 108 ha, maximum depth - 27.9 m, mean depth - 11.6 m). It included the hydroacoustic distribution of submerged macrophytes along 85 evenly distributed belt transects (perpendicularl to the shore line), creating a bathymetric chart and maps of vegetation occurrence and identifying areas occupied by hydrophytes (Cmax) and the maximum depth of lake colonization (Z). Analogous data were read from archival bathymetric chart dating from 1964-1968. The values obtained were compared with the means (and their confidence intervals) of 83 stratified lakes in Poland in different ecological status classes. Analysis of changes indicated that the ecological status of the lake had deteriorated. In the mid-1960s, the status of the lake was less than “very good” while the current status borders between “good” and “moderate.” The results indicate that the proposed method could be useful when attempting to assess changes in ecological status using archival bathymetric charts showing areas overgrown with vegetation and the distribution of it in lakes.","PeriodicalId":8293,"journal":{"name":"Archives of Polish Fisheries","volume":"111 1","pages":"33 - 42"},"PeriodicalIF":0.0,"publicationDate":"2017-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73437457","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
