Both Imidacloprid and Thiacloprid applications showed significant reductions in growth rate and chlorophyll-a content of A. platensis cultures with dose-dependent manner when the days and concentrations compared each other. SOD activity significantly decreased in the Imidacloprid application while Thiacloprid caused a significant increase only at 75 µg mL-1 concentration. APX activity significantly increased in the Imidacloprid and Thiacloprid applications at 50 µg mL-1 and 35 µg mL-1 concentrations, respectively. Imidacloprid treatment increased GR activity at 20 and 30 µg mL-1 concentrations while GR activity increased at 15, 25 and 35 µg mL-1 Thiacloprid concentrations. MDA content of A. platensis cultures did not show alterations neither with Imidacloprid nor with Thiacloprid applications. The H2O2 content did not change at all Imidacloprid concentrations. Although the H2O2 content showed a decrease at 15 µg mL-1 concentraiton, it displayed increase at 45 and 75 µg mL-1 Thiacloprid concentrations. Free proline contents increased in the Imidacloprid and Thiacloprid applications at 100 µg mL-1 and 75 µg mL-1 concentrations, respectively.

The results revealed that the average total length for the population was 91.89±15.68 mm (TL±SD) (94.75±15.91 mm for females, 88.36±14.72 mm for males), and the average total weight for the total population was 27.27±16.84 g (TW±SD) (29.02±17.54 g for females, 25.09±15.74g for males).

Four (C. torosa, Koencypris ornata, Candona lindneri, Candona meerfeldiana) of 14 ostracod taxa are new records for the ostracod fauna of Bursa province where total numbers of recent species increased to 33. Cyprideis torosa was the only dominant species found in almost all samples throughout the sampling. Based on carapace type of the species, three groups can be divided as i) Type-1 (smooth carapaces), ii) Type-2 (noded carapaces), and iii) Type-3 (carapaces noded on one valve and smooth on the other). Different occurrence patterns of the species with overlapping ecological ranges were observed among the stations. Except for station 1, all the types were encountered from other stations. Beginning from December 2018, nearly all populations had mostly Type-1 individuals until the end of March. During April-May, individuals with Types-2 and 3 appear to increase until the end of October while individuals in Type-2 group were solely found from three stations (2, 3 and 5) in March and May 2018. There was a significant difference in salinity, magnesium, and calcium values among the stations (P < 0.05) but only total nitrogen, temperature and calcium showed a medium correlation to carapace type. In all cases, populations with noded individuals were found in narrower ecological ranges for those variables than other populations with smooth individuals.","PeriodicalId":31031,"journal":{"name":"Journal of Limnology and Freshwater Fisheries Research","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41500154","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}

There are regions of the world that are understudied and little to no baseline information exists related to water quality, such as in Africa. We focused our work on the Bua River, Malawi which supports sustenance fishing and basic needs for local communities. A portion of the river has elevated levels of protection because it is found within the Nkhotakota Wildlife Reserve. We evaluated the water quality at five sites in the Bua River monthly from May 2018 to June 2020 capturing the three main seasons (warm wet, cool dry, and hot dry) to a provide baseline understanding of its water quality both longitudinally and over time and to identify possible pollution sources. Soluble reactive phosphorus (SRP) varied longitudinally with the highest values at the mouth and the lowest upstream in the Bua River, although other water quality parameters did not vary spatially. However, there were greater differences across seasons for water temperature, pH, and chlorophyll a. For example, chlorophyll a was higher during the hot dry season (3.28µgL-1) compared to the cool dry season (2.10µgL-1) and warm wet season (1.91µgL-1). Water transparency, as measured by secchi depth was lowest during the warm wet season, which coincides with higher concentrations in SRP. All measurements of salt content, Electrical Conductivity (EC), Total Dissolved Solids (TDS), and salinity) were higher during the hot dry season and correlated negatively with SRP. Similarly, bicarbonate and alkalinity were also higher during the hot dry season. Principle Component Analysis indicated that the parameters responsible for variations of Bua River water quality are mainly related to soluble minerals, water temperature, and surface runoff associated with agricultural activities and domestic waste accounting for 78.49% of the total variance in the data set","PeriodicalId":31031,"journal":{"name":"Journal of Limnology and Freshwater Fisheries Research","volume":"102 48","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41250503","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}

Artan tesis sayısı ve üretim miktarları ile birlikte son yıllarda su ürünleri yetiştiriciliğinin sucul çevreye çeşitli potansiyel etkilerinin olduğu ve bu durumun izlenmesi gerekliliği ortaya çıkmıştır. Bu kapsamda su ürünleri yetiştiriciliğinin çevresel etkilerini izlemek önem arz etmektedir. Bu çalışmada Isparta ili sınırları içerisinde yer alan Göksu Çayı üzerinde gökkuşağı alabalığı tesislerinin etkilerinin çok değişkenli istatistiki analizler kullanılarak izlenmesi ve azot ve fosfor yüklerinin tahmin edilmesi amaçlanmıştır. Ocak-Aralık (2019) aylık olarak gerçekleştirilen çalışmada yerinde ölçümler ve laboratuvarda analizler gerçekleştirilmiştir. Daha sonra tesislerin tahmini azot ve fosfor yükleri, tesislerin alabalık çiftliklerinin toplam balık üretim miktarları, yem dönüşüm oranı, toplam tüketilen yem miktarı ve azot ve fosfor içerikleri dikkate alınarak hesaplanmaya çalışılmıştır. Göksu Çayı’nda yemle gelen fosfor girdisi 13,9 ton, balıkla uzaklaştırılan fosfor miktarı 5,3 ton ve sisteme giren fosfor yükü 8,6 ton olarak tahmin edilirken yemle gelen azot girdisi 111,1 ton; balıkla uzaklaştırılan azot miktarı 29,6 ton ve sisteme giren azot yükü ise 81,5 ton olarak tahmin edilmiştir.
