The article considers the issue of assessing the long-term results of work on fisheries reclamation in inland waters of fisheries significance in Russia, carried out by the branches of the Federal State Budgetary Institution “Glavrybvod” on the state task in terms of their effectiveness. The relationship between dredging and clearing of watercourse beds and the dynamics of the number of producers of semi-navigable and non-aquatic fish in these rivers during spawning migrations has not been established. With long-term mowing of wetland vegetation in the shallow waters of reservoirs, deltas of large rivers and estuaries, there is no increase in their commercial fish productivity. A number of examples show the opposite effect of this type of work, which leads to a local deterioration of the ecological state of these reservoirs. At the same time, the repeatedly proven method of combating higher aquatic vegetation in the reservoirs of the south of Russia in low water conditions as biomelioration, based on the introduction of fish, consumers of autotrophic products by regional branches of the Federal State Budgetary Institution “Glavrybvod” is practically not used. When installing artificial spawning grounds in the littoral zone of reservoirs, regular ichthyological monitoring of the effectiveness of spawning on them is not carried out. There are no reliable data confirming the significant positive impact of artificial spawning grounds on the population dynamics of commercial fish species of the limnophilic ecological group under conditions of significant spring water level depletion in Russian reservoirs. When catching predatory and low-value fish species in water bodies, legal obstacles arise due to the fact that the volume of seizure of predatory fish includes commercial objects for which the ODE is established annually and their catch is already carried out according to industrial quotas.

Annotated Checklist

The current status of the inland waters ichthyofauna of Turkey is revised, and an updated checklist of the freshwater fishes is presented. The latest checklist included all species listed in the available previous study that was published in 2015, which is now updated after a period of five years. We revised the validity of previously accepted species and added newly described and reported species in Turkey. Some previously erroneously reported species and not established alien fishes were excluded from this checklist. A total of 384 fish species belonging to 20 orders and 34 families have been reported in the inland waters of Turkey. Among these, 15 species (3.9%) are non-native and 208 species (54.2%) are considered as endemic to Turkey. A total of 119 species previously reported from Turkey have been excluded from Turkish ichthyofauna list, either in the present study or in previous studies.

Abstract The food spectrum and trophic and length–weight characteristics of an invasive species, South American suckermouth armored catfishes Pterygoplichthys spp. (Loricariidae), from lotic and lentic inland waters of Vietnam have been studied. It is found that the diet of suckermouth armored catfishes consists of plant and animal food, as well as organic detritus. According to the predominant type and pattern of feeding, suckermouth armored catfishes can be classified as detritivore gatherers (janitor). Some specimens of catfish with a high consumption of animal food have been identified. It is noted that invasive suckermouth armored catfishes can be a significant food competitor for aboriginal fish species; detritivores; and, possibly, benthophages in the lotic and lentic inland waters of Vietnam.

A study was conducted on fish species composition and morphological features of five dominant fish families from the inland waters of Kebbi state, Nigeria between January and December 2017. Three major fishing communities (Argungu, Sabiyel and Yauri) were selected for the study. Fish samples were qualitatively collected from the commercial landings of the fishermen using gill nets. The analysis of the distribution of fish species were analyzed using Microsoft Excel software In total 18 fish species belonging to 10 families were identified from the inland waters of Kebbi state. Viz: Bagridae, Cichlidae, Claridae, Mormyridae, Citharacidae, Characidae, Mochokidae, Melaptaruridae, Schilbeidae and Cyprinidae. Among the 10 identified families, Bagridae (22.22%) and Mormyridae (16.66%) which accounted for four and three species respectively, were the most dominant families.

Abstract This paper discusses the problem of the occurrence of non-native fish species in a strongly transformed aquatic ecosystem. The changes in this ecosystem are caused by warm water discharges from two electric power plants. Twelve non-native fish species are confirmed to occur in the system of five heated lakes located in central Poland. In total, 30% of the total number of non-native species confirmed in Polish inland waters were noted. Aquaculture and fisheries are the primary sources of non-native species in these lakes. Among the species identified, most reached the lakes or canals by escaping from farming facilities or through commercial stocking. Four species have established stable populations. Pseudorasbora parva (Temminck & Schlegel), Carassius gibelio (Bloch), and Carassius auratus (L.) are invasive species that occur abundantly in all the lakes, while Cyprinus carpio L. reproduces irregularly and only in the most heated lakes. The remaining species do not reproduce in the heated lakes system, or anywhere else in Poland; still, the threat these species pose must not be underestimated.
