“…The changes in zooplankton are often deduced from comparing stocked and unstocked lakes (Liss et al 1998;Knapp et al 2001;Schabetsberger et al 2006). In the Alps, only Brancelj (1999) consistently monitored the shift in the zooplankton community after stocking of Lake Dvojno Jezero situated in the Triglav National Park of Slovenia.…”

The zooplankton community of Alpine lake Seehornsee (1,779 m a.s.l.) was studied over a period of 13 years. In 1994, a typical high-altitude zooplankton community, consisting of two calanoid copepods (Mixodiaptomus laciniatus, Arctodiaptomus alpinus), one cladoceran (Daphnia rosea), and two rotifers (Keratella quadrata, Synchaeta pectinata) coexisted with infertile charr hybrids, which had been introduced in 1969 and again in 1974. When the aged fish were removed by intensive gill netting, they had fed predominantly on aquatic insects. After a fish-free period of 4 years, 2000 fertile juvenile Alpine charr (Salvelinus umbla) were stocked in 1998 and again in 1999. They preyed on benthic (chydorids, ostracods, cyclopoid copepods, chironomid larvae and pupae) and planktonic prey (diaptomid copepods, Daphnia). Between 2004 and 2006 charr successfully reproduced. Nine years after stocking of fertile charr, the two calanoids had virtually disappeared, and Daphnia rosea had notably declined in abundance. In concordance with the size efficiency hypothesis (Brooks and Dodson 1965), the newly appearing and smaller cladoceran Ceriodaphnia pulchella, together with the two resident, and two emerging species of rotifers (Polyarthra luminosa, Gastropus stylifer) dominated the zooplankton community.

“…Zooplankton plays a significant role in aquatic ecosystems [22] by regulating the nutrient cycle and transportation of nutrients in lakes, rivers, estuary, and seas [23][24][25][26]. Physico-chemical factors and nutrient status of water control zooplankton biomass.…”

Zooplankton is microscopic organisms that drift in water due to the wave action of water. Zooplankton is mainly visible in the pelagic zone of ponds, lakes, rivers, and oceans where light enters. They have no strong swimming organ-like fin in fish [1]. That's why they are unable to swim freely like fish and they have relied on the wave or current to swim [2]. Zooplankton act as a base of food chains and food webs in freshwater ecosystems since they are solely liable for all secondary production [1]. Moreover, some of them are known as indicators of ecological variations [3]. Zooplankton is now subjected to the effect of the global climate change phenomenon and its long-term and wide profound effect [4]. Directly or indirectly omnivorous and carnivorous fishes rely on zooplankton for their food [5]. Zooplankton excretes organic matters and provides large quantities of protein in water. These nutrients are required for the development of different organs of fish that promote rapid growth [6]. Zooplankton regarded as the ideal food source for brood fishes. Carps fish larvae and white fish (Mullet) larvae mostly feed on zooplankton [7]. Zooplankton is the main food item of Xenentodon cancila and while Cirrhina reba's feed mainly constitutes of zooplankton [8]. About 82% of the food item of Anabas testudineus [9], 32% of Notoptrus notoptrus [10], 23% of Macrobrachium rosenbergii, 47% of Catla catla [11], 6.37% of Labeo rohita [11],

Two pairs of neighboring subalpine lakes located in the Northern Calcareous Alps of Austria were investigated. Each pair comprised a deeper lake containing European minnows (Phoxinus phoxinus), and a corresponding shallower lake harboring Alpine newts (Triturus alpestris) as top predators. Plankton successions within fish and amphibian lakes differed markedly from each other. Throughout the year rotifers numerically dominated within the minnow lakes, while pigmented copepods (Genera Heterocope, Acanthodiaptomus, Arctodiaptomus, Mixodiaptomus) and Daphnia were prominent in the amphibian lakes, at least early during the ice-free period. We argue that size-selective predation by minnows was the ultimate reason for this predominance of smaller zooplankton. While one of the minnow lakes was characterized by a succession of spatially and temporally segregated rotifer species, the other minnow lake permitted the development of populations of small-sized Bosmina and Ceriodaphnia during summer, probably due to the existence of a strong oxycline allowing zooplankton crustaceans to avoid predation from shore-based shoals of minnows. Once trout were introduced into this lake, minnows were visibly reduced in abundance. Bosmina and Ceriodaphnia disappeared and Daphnia together with a predacious copepod (Heterocope) emerged either from egg banks or arrived from nearby source populations. We argue that the crustacean communities within the fishless lakes were adapted to the comparatively weak predation rates of Alpine newts.
