Abstract:
Background. In the context of ongoing water salinization and increasing water temperature in the Azov Sea, a decrease in the stocks of anadromous and semi-anadromous fish species has been observed. As a result of the increase in salinity, by 2020, favorable conditions for shrimps had developed in the Azov Sea, which made it possible to include them into the list of major fishing targets. Relevance. These factors necessitate the analysis of fisheries dynamics in the Azov Sea. The aim of this work is to review the status of the shrimp stock and fishery in the context of changing habitat conditions. Methods. This work is based on the statistical data provided by the FSBI “Center for Fisheries Monitoring and Communication” and the Azov-Black Sea Territorial Administration of the Federal Agency for Fisheries, as well as the data collected during expeditionary surveys in 1990–2024. Results. As a result of the conducted research, it has been found that, in the context of increasing salinity levels, the shrimp exploitable stock increased 27-fold from 2015 to 2024. The main commercial aggregations have been recorded in the Northern Azov Region. As compared to 2015, catch volumes have increased by almost 147 times. Realization of the recommended catch was at 79–81 %. The highest gross catch of 160.7–184.0 t was recorded in the Zaporozhye Region, where shrimp fishing operations were carried out in the Obitochny, Berdyansk Bays and the Utlyuk Estuary (Liman); the lowest catch (21.3 t) was in the Donetsk People's Republic. The total body length of shrimp in the catches varied from 2.3 to 5.3 cm. The share of non-commercial size shrimp did not exceed 7 %. Conclusion. In the context of increasing salinity of the Azov Sea waters, an active increase in the shrimp commercial stocks up to 3 thousand t has been recorded. With the deterioration of the stocks of traditional fishing targets, an interest in the shrimp harvesting has been observed. This resulted in an unprecedented for the Azov Sea shrimp catch reaching 445 t. Considering the largest catch volumes and the number of fishers actively engaged in fishing operations, the Northern Azov Region experiences the highest fishing pressure. However, given the satisfactory condition of the shrimp stocks, it should be concluded that the commercial potential of these areas has not yet been realized. With the growing interest of fishers in the new fishing targets and expansion of fishing areas, an increase in the catches of commercial invertebrates should be expected.

Abstract:
Каменная креветка Palaemon elegans Rathke, 1836 – широко распространенный инвазивный вид, бентофаг-полифаг, значимый в питании рыб, в ряде стран – промысловый объект. После вселения в Балтийское море успешно акклиматизировалась, широко распространилась, вытеснив аборигенные виды креветок палемонов. Наблюдается недостаток знаний о биологии креветки из морских поселений у берегов Калининградской области. Получены новые данные о размерных, половых, весовых характеристиках и репродукции P. elegans Юго-Восточной Балтики. Соотношение полов чаще приближалось к равному, общая длина тела составила 9,8–50,0 мм при длине карапакса 4,0–11,6; максимальные размеры самок больше, чем самцов. Масса тела креветок достигала 1,37 г; весовой рост несколько опережал линейный. Первое спаривание у самок могло происходить при длине карапакса до 5 мм; при 4–9 мм они впервые созревали и нерестились, откладывая до 1500 яиц размерами 0,45–0,58 х 0,50–0,60 мм, эмбрионов вынашивали. За первую половину эмбриогенеза наблюдалось увеличение объема яиц в среднем в 1,4 раза; значимых потерь эмбрионов не обнаружено. За нерестовый сезон (май – начало сентября) самки могут размножаться минимум дважды. Оценка половых, размерных, репродукционных параметров у креветок трех морских поселений показала их достаточное единообразие. Сравнение полученных результатов с таковыми для креветок Калининградского залива позволило предположить, что поселения моря и залива – части одной популяции вида Palaemon elegans в водах Калининградской области.

Abstract:
Water permeability [based on the half-time of exchange of body water with the environment (T1/2)] of the upper estuarine prawn Palaemon longirostris was measured in a range of salinities at 4, 12 and 20°C. Prawns acclimated for 7 days were compared with prawns exposed to acute salinity changes. Acclimation to low salinity and low temperature caused a significant reduction in permeability. Transfer of prawns from 34 to 0.5‰ had no immediate effect on permeability; however, transfer from 0.5 to 34‰ caused an immediate significant rise in permeability. Heart rate of P. longirostris acclimated to 0.5 and 34‰ at 4, 12 and 20°C was unaffected by salinity, but was significantly reduced at low temperature. The permeabilities of three other prawn species (Palaemonetes varians, Crangon crangon and Palaemon elegans), which have different horizontal distributions in estuaries and different salinity tolerance ranges, were also studied and compared with the values obtained for P. longirostris. P. varians and C. crangon showed significantly reduced permeabilities at low compared with high salinities; however, the permeability of P. elegans was unchanged at the two salinities used for this species (22 and 34‰). At each experimental salinity, permeabilities followed the sequence: P. longirostris<P. varians<C. crangon<P. elegans. Results show that reduction of permeability is an important physiological adaptation to life in dilute saline regions and may be involved in separating species with overlapping salinity tolerance ranges.

Abstract:
The impact of invasive alien species on native communities can act at different levels both by affecting the ecosystem’s structure (i.e., mainly in the case of vegetation) and through direct interactions (i.e., competition for food or space). Behavioral studies under controlled conditions can provide relevant information on both the invasive potential of alien species and the potential impact of the invaders on the local native species. In the laboratory, the competition for food resources between the invasive oriental shrimp Palaemon macrodactylus, Rathbun, 1902, and the Mediterranean native shrimp Palaemon elegans, Rathke, 1836, was analyzed. These species are typical residents of coastal transitional and estuarine waters, so the experiments were carried out using two salinity conditions that characterize the coastal lagoon of Venice. Although at both salinity treatments the alien species tended to be more aggressive than the native one, significant differences between the two species were mainly observed at a salinity of 30. In particular, at a salinity of 30, P. macrodactylus spent more time attending to the food source than the native species. The results are discussed in light of the potential inter-specific competition between the two species within the conditions of the Venice lagoon.

Abstract:
We have found that two very common species of North Atlantic shallow water shrimp, Palaemon adspersus and Palaemon elegans , remove and feed on ectoparasites on plaice ( Pleuronectes platessa L.). The relationship could be mutualistic, as we did not observe any attempts by the fishes to feed on the shrimps. The ectoparasites removed included monogenean worms ( Gyrodactylus sp.) and sea lice ( Lepeophtheirus pectoralis ). An experiment showed that there were 65% more Gyrodactylus parasites on the fishes that had been apart from compared with those that had been together with shrimps for 48 h. Shrimps on coral reefs are known for cleaning fishes, but that shrimps in temperate waters show parasite-cleaning behaviour is, to our knowledge, a new observation.

Abstract:
Using DAPI as a nucleus marker, we studied zoeas of 6 decapods (Palaemon adspersus Rathke, 1837; Palaemon elegans Rathke, 1837; Porcellana platycheles (Pennant, 1777); Pisidia longicornis (Linnaeus, 1767); Xantho hydrophilus (Herbst, 1780) Xantho pilipes A. Milne Edwards, 1867) representing one species pair of Palaemonidae (Caridea), Porcellanidae (Anomura) and Xanthidae (Brachyura) each, with special reference to the telson, and correlated our observations with the general morphological features of the zoeas. The different taxa exhibit specific features with respect to the distribution of nuclei, the patterns they exhibit, their size, density and numbers, thus being sets of characters potentially useful for taxonomic descriptions and diagnoses especially on the “above-species”-level. We discuss how nuclear patterns and classical morphological and/or morphogenetical features normally examined in zoeal larvae are related, and give some ideas on how “nucleus”characters can contribute to taxonomic descriptions.

Abstract:
The LS5096 h of prawn, Palaemon elegans, was determined at various salinities (0–45 ppt) with the Caspian Sea salt proportion. In addition, growth indices, survival and moulting at salinities 8, 13 and 18 ppt were also studied during four weeks. All the experiments were carried out in the laboratory (24±1°C). The results showed that more than 50% of the prawns survived at 1 to 30 ppt salinity range, while above and below this range, less than 50% survived within 24 hours. No significant differences (*P > 0.05) in growth parameters such as carapace length (CL) increase, specific growth rate (SGR) and also in survival and moulting rates were observed in prawns reared in salinities 8, 13 and 18 ppt. Mean intermoult period in each salinity was 8.12 ± 3.07, 8.61 ± 2.96 and 8.92 ± 3.47 days, respectively. Salinity 8–18 ppt was found to be the optimum range for P. elegans in the studied length range (CL, 6–9 mm).

Full text
Abstract:
Ocean pollution poses a significant issue in the marine ecosystem. Coastal areas are particularly impacted by this pollution, and consequently, organisms associated with these coasts bear the brunt of its effects. Therefore, the presence of robust bioindicators, such as the shrimp species Palaemon elegans, is critically important. In this study, 20 P. elegans specimens were examined in each of the five areas on Gran Canaria Island. Water samples were collected to assess the potential existence of elevated concentrations. Significant discrepancies were observed in the levels of Al and Li across all zones, except those previously mentioned. The highest concentrations were recorded in Arguineguín (Southern sector), reaching 49.14 ± 4.51 mg/kg (Al) and 47.64 ± 2.86 mg/kg (Li). The authors contend that P. elegans proves to be a reliable bioindicator for tourist and port-related pollution, specifically for the metals Al, Zn, Cd, Pb, Ni, Fe, B, and Li analyzed in this research.

Abstract:
The littoral prawn Palaetnon elegans Rathke regulates the body concentration of zinc at higher external zinc concentrations in the presence of EDTA. The dissolved zinc concentration in artificial sea water corresponding to the threshold of regulation breakdown changed from ca. 100 μg Zn 1-1 (ca. 1.53 μmol Zn 1-1) without EDTA, to ca. 316 μg Zn 1-1 (ca. 4.8 μmo1 Zn 1-1) in the presence of 8.6μmol EDTA 1-1 at 10 °C. The regulated body Zn concentration remained unchanged at 77–79 μg Zn g-1 dry wt with or without EDTA. Increased levels of EDTA in the medium decreased the rate of uptake of labelled zinc by P. elegans. The presence of 3 μmol EDTA 1-1 decreased the mean Zn uptake rate of prawns in 100 fig Zn 1-1 (ca. 1.53 μmol Zn 1-1) from 2.9 to 0.25% of total body Zn g-1 day"1 at 10 °C. The increased ability of P. elegans to regulate zinc in the presence of EDTA may be explained by the reduced bioavailability of the zinc-EDTA complex for uptake. There is marked individual variation in the rate of uptake of labelled zinc in prawns, even in the presence of the same concentration of zinc or zinc-EDTA.

Abstract:
The Atlantic–Mediterranean transition zone between the Alborán Sea and the Gulf of Cádiz constitutes the most prominent marine geographic barrier in European waters and includes known phylogeographic breaks such as the Strait of Gibraltar and the Almería-Oran Front. A genetic shift in this area has been previously documented for the European littoral shrimp Palaemon elegans. Here we carried out a phylogeographic analysis with the congeneric and sympatric species Palaemon serratus to test for similar intraspecific genetic differentiation and geographic structure. This littoral prawn is distributed in the Northeastern Atlantic Ocean, the Mediterranean Sea and the Black Sea. We compared DNA sequences from the mitochondrial genes Cox1 and to a lesser extent from 16S rRNA of several Atlantic and Mediterranean populations. Furthermore, sequences from the nuclear gene Enolase were included for corroborating differences between Mediterranean and Atlantic individuals. A pronounced genetic differentiation was detected between the Mediterranean and Atlantic populations, amounting to 10.14% in Cox1 and 2.0% in 16S, indicating the occurrence of two independent evolutionary lineages. Interestingly, specimens from the Atlantic Gulf of Cadiz cluster together with the Mediterranean individuals, indicating that a biogeographic barrier appears to be located west of the Strait of Gibraltar.

Abstract:
The seaweed Asparagopsis armata exhibits a strong invasive behavior, producing halogenated compounds with effective biological effects. This study addresses the biochemical responses to sublethal concentrations of A. armata exudate on the marine snail Gibbula umbilicalis whole body and the shrimp Palaemon elegans eyes and hepatopancreas. Antioxidant defenses superoxide dismutase (SOD) and glutathione-S-transferase (GST), oxidative damage endpoints lipid peroxidation (LPO) and DNA damage, the neuronal parameter acetylcholinesterase (AChE), and the fatty acid profile were evaluated. Results revealed different metabolic responses in both species. Despite previous studies indicating that the exudate affected G. umbilicalis’ survival and behavior, this does not seem to result from oxidative stress or neurotoxicity. For P. elegans, the inhibition of AChE and the decrease of antioxidant capacity is concomitant with the increase of LPO, suggesting neurotoxicity and oxidative stress as contributor mechanisms of toxicity for this species. Fatty acid profile changes were more pronounced for P. elegans with a general increase in polyunsaturated fatty acids (PUFAs) with the exudate exposure, which commonly means a defense mechanism protecting from membrane disruption. Nonetheless, the omega-3 PUFAs arachidonic acid (ARA) and docosapentaenoic acid (DPA) increased in both invertebrates, indicating a common regulation mechanism of inflammation and immunity responses.

Abstract:
Only two species of shrimps live in the Caspian Sea: Palaemon elegans and P. adspersus (Crustacea, Decapoda: Palaemonidae), which were introduced to the Caspian Sea in 1931-1934 during the introduction of mullets. Data on the biology of these species of shrimps are reflected only in the works by E.N. Kudelina (1950) and M.P. Marochkina (1980). This determines the relevance of research on the current state of the Caspian shrimp population. The material was collected in various areas of the Middle Caspian Sea in the summer-autumn period. Both species live up to five meters deep. P. elegans prefer coastal underwater objects with dense thickets, P. adspersus - open shallow waters with sandy-muddy soil. To the north of Makhachkala, P. elegans predominates, to the south, the number of both species is the same, and to the east, P. adspersus dominates. The characteristics of breeding females are presented, and the dependence of fecundity on the length of egg-bearing females is revealed. The absolute fecundity increased with the increase in the size of the females. Regression equations reflecting the relationship between fecundity and length of egg-bearing females of P. elegans and P. adspersus are calculated, expressed by power equations, respectively: E = 0.044947 · L265356 and E = 2.323 · L17.4, where: E - fecundity, L-length. In October 2017, in May and October 2018, several specimens of the subtropical freshwater shrimp Macrobrachium nipponense were found downstream of the Terek River. Probably, in the near future, the species composition of the Caspian shrimp will be replenished with another species.

Full text
Abstract:
Deep-sea species endemic to hydrothermal vents face the critical challenge of detecting active sites in a vast environment devoid of sunlight. This certainly requires specific sensory abilities, among which olfaction could be a relevant sensory modality, since chemical compounds in hydrothermal fluids or food odors could potentially serve as orientation cues. The temperature of the vent fluid might also be used for locating vent sites. The objective of this study is to observe the following key behaviors of olfaction in hydrothermal shrimp, which could provide an insight into their olfactory capacities: (1) grooming behavior; (2) attraction to environmental cues (food odors and fluid markers). We designed experiments at both deep-sea and atmospheric pressure to assess the behavior of the vent shrimp Rimicaris exoculata and Mirocaris fortunata, as well as of the coastal species Palaemon elegans and Palaemon serratus for comparison. Here, we show that hydrothermal shrimp groom their sensory appendages similarly to other crustaceans, but this does not clean the dense bacterial biofilm that covers the olfactory structures. These shrimp have previously been shown to possess functional sensory structures, and to detect the environmental olfactory signals tested, but we do not observe significant attraction behavior here. Only temperature, as a signature of vent fluids, clearly attracts vent shrimp and thus is confirmed to be a relevant signal for orientation in their environment.

Abstract:
Abstract For studying benthic macrofaunal composition associated with seagrass rocky beds of the southern Caspian Sea, two time samplings were carried out along the coast line in the winter and summer of 2013. In total, 1,286 specimens of the five species were identified: Pontogammarus maeoticus, Balanus improvisus, Mytilaster lineatus, Palaemon elegans and Alitta succinea. The total recorded abundance was 5,675 and 755 ind./m2, with a biomass of 147,271 and 31,238 mg/m2 in the winter and summer respectively. The collected species in this study are generally non-indigenous (except P. maeoticus) and could potentially have an effect on native benthic fauna, as an additional food source could facilitate the commercially exploited fish stocks. Thus further studies are required to monitor their potential interactions on the Caspian Sea fauna
