The downstream stretch has been affected by the Nove Mlyny Reservoir system, both as a barrier to natural migration of native rheophilic
fish from the rivers Morava and Danube but also as a source of non-native species (e.
European chub, Squalius cephalus (Linnaeus, 1758) is rheophilic
(Schiemer and Waidbacher, 1992) that has dominated in ichthyofuana of Turkey.
The shift from endogenous to exogenous feeding is a major difficulty faced in farming juveniles of rheophilic
species (Gerking, 1994), as well as cannibalism that occurs in the first days of larval life (Feiden, Hayashi, & Boscolo, 2006).
Therefore, we recommend that IBAMA should change this normative because our results indicated that the closed season for this species is between February 1 and May 31; however, the closed season of other species with rheophilic
habits present at this hydrographic basin should be reviewed.
On the other hand, there was a negative impact on the rheophilic
It is a rheophilic
species with high fertility rates reaching up to 15 kg of body weight (Arantes, Santos, Rizzo, & Bazolli, 2011).
Vegetation associated with this type of water were rheophilic
bryophytes and riparian plants such as Cyclanthaceae, Zyngiberaceae, Clusiaceae, Mimosaceae (Inga), Arecaceae, Melastomataceae, and Rubiaceae.
Less-tolerant or rheophilic
families such as Baetidae and Simuliidae can face decline or expiration in prolonged drought conditions, while more tolerant species such as Chironomidae and Ceratopogonidae can become more abundant (Wright and Symes 1999).
The clown knifefish Chitala chitala (Hamilton - Buchanan) also known as feather back chital is a rheophilic
important freshwater fish found widely in benthic waters and has been considered as an important freshwater food as well as ornamental fish (Ponniah and Sarkar, 2000; Ayyappan et al.
Studies on sperm cryopreservation in Brazil have focused on rheophilic
fish species, such as dourado, Salminus brasilienses (CAROLSFELD et al.
The main project goal is the improvement of conservation status of six small rheophilic
fish species and a mollusc species listed in Annex II of the EU Habitats Directive in selected river sections in Natura 2000 sites in the Bulgarian Danube river basin.
The appearance of the rheophilic
component, including Meridion circulare and Ceratoneis arcus, in the sediment diatom record is further evidence that might be related to Lake Kooraste Koverjarv being supplied by an inflowing artificial ditch.
