A Concise Study On Essential Parameters For The Sustainability Of Lagoon Waters In Terms Of Scientific Literature, Shuraik Kader, Morufu Olalekan Raimi, Velibor Spalevic, Austin-Asomeji Iyingiala, Raheem Waliyat Bukola, Lizny Jaufer, Talib E. Butt
Turkish Journal of Agriculture and Forestry
Agriculture encompasses both plant growing (agronomy, horticulture, and forestry) and animal husbandry. Aquaculture is the aquatic embodiment of agriculture. Lagoons are the main sources of aquaculture in various countries around the world which especially yield shrimp, finfish, macrophytes, and mollusk. Agricultural effluents are highly affecting the lagoon water quality parameters in Sri Lanka since most of the agricultural farmlands in the country are on coastal landmasses. It leads to the increased risks of lagoon water contamination. Therefore, it is essential to identify the water quality parameters affected by anthropogenic agricultural activities and establish their threshold limits for ensuring the sustainability …

Effect Of Water Quality On Production Performance Of Lactating Nili-Ravi Buffaloes, Muhammad Asim Tausif, Faisal Shahzad, Jalees Ahmed Bhatti, Sundas Qamar, Anjum Khalique, Hifz-Ul Rahman, Hafiz Muhammad Ali, Azfar Hussain
Turkish Journal of Veterinary & Animal Sciences
The study was conducted to evaluate the effects of drinking water quality on the milk production performance of Nili-Ravi buffaloes. Lactating Nili-Ravi buffaloes (n = 12) of the same parity were randomly divided into three groups: A, B, and C (n = 4). Group A was offered turbine water, group B (the control) was kept on tap water, and group C was given canal water for drinking. Mean daily milk production was found significantly (P < 0.01) higher for group A as compared to the other groups. Dry matter intake (DMI) was lowest in group B followed by group A. Milk composition, including fat, solid not fat, and total solid percentages, was found statistically different (P < 0.001) among all groups. Feed efficiency was higher in the control (group B) followed by group C and group A. A significant (P < 0.001) difference for water intake was also observed among all groups. In conclusion, buffaloes kept on tap drinking water showed better milk production performance.

A Comparative Study Of The Aquatic Insect Diversity Of Two Ponds Located In Cachar District, Assam, India, Arpita Dalal, Susmita Gupta
Turkish Journal of Zoology
Ponds play a vital role in the conservation of aquatic biodiversity at the local level apart from other lakes and rivers. A comparative study was carried out on the aquatic insect diversity of two different ponds, one in an urban area (urban pond, UP) and another in a rural area (Jalinga pond, JP). Two seasonal collections (postmonsoon and winter) were made to check the pollution status of the two ponds based on the aquatic insect community and physicochemical properties of water. Consequently, 29 species, 17 families, and 5 orders of aquatic insects from UP and 17 species, 8 families, and …

The Phytoplankton Functional Group Concept Provides A Reliable Basis For Ecological Status Estimation In The Çaygören Reservoir (Turkey), Kemal Çeli̇k, Tuğba Ongun Sevi̇ndi̇k
Turkish Journal of Botany
The phytoplankton functional group (FG) concept has been successfully used to determine water quality states in both lake and river systems, but is not yet stressed in regular studies in reservoir environments. The purpose of our study was to estimate the ecological status of the temperate Çaygören Reservoir (2007-2009) using the Q(r) FG composition metric, and to test whether it is able to follow the main structuring of the physical and chemical parameters studied. The main occurring coda were codon C (Cyclotella meneghiniana Kützing, Stephanodiscus neoastraea Hakansson and Hickel), codon T (Gloeotila subconstricta (G.S. West) Printz, Mougeotia sp.), codon X2 …

Evaluation Of Vertical And Horizontal Changes In Community Structure Of Zooplankton In A Deep Dam Lake, Di̇dem Gökçe, Duygu Özhan Turhan
Turkish Journal of Zoology
The purpose of this study was to describe the horizontal and vertical distributions of the zooplankton community structure in Karakaya Dam Lake. Rotifers were numerically dominant (81.89%) in the community during the study period; they were followed by Copepoda (10.32%) and Cladocera (7.79%). In the metalimnetic maximum oxygen zone between 5 and 10 m, cladocerans made up 70.1% of the total number of zooplankton in June and 27.3% of the total number of zooplankton in November. Oxygen values decreased at 10 and 15 m in September and November. While the abundance of rotifers and cladocerans decreased as well, cyclopoids increased …

The Ecology Of Freshwater Bivalves In The Lake Sapanca Basin, Turkey, Ertan Ercan, Özcan Gaygusuz, Ali̇ Serhan Tarkan, Martin Reichard, Carl Smith
Turkish Journal of Zoology
Despite the ecological importance and globally threatened status of freshwater bivalves, the freshwater mussel fauna of Turkey has hitherto received little attention. The aim of this study was to describe the ecology of freshwater mussels of the Lake Sapanca basin (northwest Turkey) to provide baseline data against which to measure future trends. Five native mussel species belonging to 3 genera were encountered in surveys: Anodonta cygnea, A. anatina, Unio pictorum, U. crassus, and Dreissena polymorpha. In addition, an invasive species from Asia, A. woodiana, was recorded in the region for the first time. A. cygnea and U. pictorum were the …

The Seasonal Succession Of Diatoms In Phytoplankton Of A Soda Lake (Lake Hazar, Turkey), Mehmet Ali̇ Turan Koçer, Bülent Şen
Turkish Journal of Botany
Some physicochemical variables and climatic effects on the succession of a diatom community in the plankton of the pelagic zone of Lake Hazar, an alkaline soda lake, were investigated. Monthly diatom samples were collected from the surface water at western, central, and eastern pelagic areas of the ellipsoid-shaped lake using a plankton net from November 2004 to October 2005. When high temperature and pH levels prevailed in May and September, Epithemia, Rhopalodia, Cocconeis, and Cyclotella were dominant. Cymbella was dominant in early spring and late autumn, but was not significantly correlated with temperature or pH. The species of Gomphonema, Fragilaria, …

An Evaluation Of The Water Quality Of Yuvarlakçay Stream,In The Köycegiz-Dalyan Protected Area, Sw Turkey, Ni̇lgün Kazanci, Muzaffer Dügel
Turkish Journal of Zoology
The longitudinal and seasonal distribution of macroinvertebrates and the physical and chemical variables of Yuvarlak Stream in the Köycegiz-Dalyan Protected Area in South-Western Turkey were studied between April 1992 and April 1993. The diversity, frequency, dominance, abundance and similarity of macroinvertebrates through the year were recorded. In addition, the Belgian Biotic Index was used as a biological criterion for the assessment of water quality for the first time in Turkey. According to the physico-chemical variables and the distribution of benthic macroinvertebrates, continuous slight and moderate organic pollution exists in the stream. The monitoring of the water quality of Yuvarlakçay Stream …
