The new species, M. miyakoense, is compared with other five stygiobiont species of the genus char- acterized by a reduced eye, i.e. M. cavernicola (Kemp, 1924), M. villalobosi Hobbs, 1973, M. acherontium Holthuis, 1977, M. microps Holthuis, 1978, and M. poeti Holthuis, 1984. It is the first representative of stygiobiont species of Macrobrachium from East Asian waters. Key words: Crustacea, Decapoda, Caridea, Palaemonidae, Macrobrachium, new species, anchia- line cave, Miyako Island, Ryukyu Islands Introduction There are few stygiobiont species of the palaemonid genus Macrobrachium Bate, 1864 in the world, although the genus is one of the most speciose caridean genera, abundant in tropical fresh waters (Chace & Bruce, 1993). Holthuis (1986) listed six stygiobiont species of Macrobrachium, together with additional 12 stygiophile or stygoxene species. The six stygiobiont species are: M. cavernicola (Kemp, 1924) from Siju Cave in Assam, India (Kemp, 1924); M. -

Feeding habits of the prawns Processa edulis and Palaemon adspersus (Crustacea, Decapoda, Caridea) in the Alfacs Bay, Ebro Delta (NW Mediterranean).- The stomach contents of 147 Palaemon adspersus Rathke, and 102 Processa edulis (Risso) were analyzed. The frequency of occurrence method and the points method were used. The role of these species in the food web of Cymodocea nodosa meadows is defined. Results indicate that both species are predators of benthic invertebrates rather than scavengers or detritus feeders. The main food items varied according to species. The diet of Palaemon adspersus consisted almost entirely of crustaceans, molluscs, and plant material, with amphipods playing a major role. Processa edulis ate an almost equal amount of crustaceans and polychaetes. In P. adspersus, most dietary items differed according to size classes of prawn.

The First Amber Caridean Shrimp from Mexico Reveals the Ancient
www.nature.com/scientificreports Corrected: Author Correction OPEN The frst amber caridean shrimp from Mexico reveals the ancient adaptation of the Palaemon to the Received: 25 February 2019 Accepted: 23 September 2019 mangrove estuary environment Published online: 29 October 2019 Bao-Jie Du1, Rui Chen2, Xin-Zheng Li3, Wen-Tao Tao1, Wen-Jun Bu1, Jin-Hua Xiao1 & Da-Wei Huang 1,2 The aquatic and semiaquatic invertebrates in fossiliferous amber have been reported, including taxa in a wide range of the subphylum Crustacea of Arthropoda. However, no caridean shrimp has been discovered so far in the world. The shrimp Palaemon aestuarius sp. nov. (Palaemonidae) preserved in amber from Chiapas, Mexico during Early Miocene (ca. 22.8 Ma) represents the frst and the oldest amber caridean species. This fnding suggests that the genus Palaemon has occupied Mexico at least since Early Miocene. In addition, the coexistence of the shrimp, a beetle larva, and a piece of residual leaf in the same amber supports the previous explanations for the Mexican amber depositional environment, in the tide-infuenced mangrove estuary region. Palaemonidae Rafnesque, 1815 is the largest shrimp family within the Caridea, with world-wide distribution1. It is now widely believed that it originated from the marine environment in the indo-western Pacifc warm waters, and has successfully adapted to non-marine environments, such as estuaries and limnic environments2–4. Palaemon Weber, 1795 is the second most species-rich genus besides the Macrobrachium Spence Bate, 1868 in the Palaemonidae4–6. Te 87 extant species of Palaemon are found in various habitats, such as marine, brackish and freshwater7,8. -

click for previous page - 108 - Interest to Fishery: Lindner (1957:21) described the present species together with Exhippolysmata oplophoroides as "in British Guiana the most abundant commercial forms", where they are either sold on the local market or exported in a dried state. In Surinam it is also of great commercial importance and next to Xiphopenaeus it is the most important species fished for locally; here too the dried product is exported, the fresh and also dried shrimp is sold at the local markets. In French Guiana, however, the species is "parfois utilisée dans l'alimentation, elle n'est que peu appréciée (Durand, 1961:33). In N.E.

Composition, Seasonality, and Life History of Decapod Shrimps in Great Bay, New Jersey
20192019 NORTHEASTERNNortheastern Naturalist NATURALIST 26(4):817–834Vol. 26, No. 4 G. Schreiber, P.C. López-Duarte, and K.W. Able Composition, Seasonality, and Life History of Decapod Shrimps in Great Bay, New Jersey Giselle Schreiber1, Paola C. López-Duarte2, and Kenneth W. Able1,* Abstract - Shrimp are critical to estuarine food webs because they are a resource to eco- nomically and ecologically important fish and crabs, but also consume primary production and prey on larval fish and small invertebrates. Yet, we know little of their natural history. This study determined shrimp community composition, seasonality, and life histories by sampling the water column and benthos with plankton nets and benthic traps, respectively, in Great Bay, a relatively unaltered estuary in southern New Jersey. We identified 6 native (Crangon septemspinosa, Palaemon vulgaris, P. pugio, P. intermedius, Hippolyte pleura- canthus, and Gilvossius setimanus) and 1 non-native (P. macrodactylus) shrimp species. These results suggest that the estuary is home to a relatively diverse group of shrimp species that differ in the spatial and temporal use of the estuary and the adjacent inner shelf. Introduction Estuarine ecosystems are typically dynamic, especially in temperate waters, and comprised of a diverse community of resident and transient species. These can include several abundant shrimp species which are vital to the system as prey (Able and Fahay 2010), predators during different life stages (Ashelby et al. 2013, Bass et al. 2001, Locke et al. 2005, Taylor 2005, Taylor and Danila 2005, Taylor and Peck 2004), processors of plant production (Welsh 1975), and com- mercially important bait (Townes 1938). -

Crabs were collected monthly between February 2010 and January 2012 and totaled 1,837 individuals. Sex ratios were similar between males and females in the first year and differed in the second. Sex ratios by size class differed statistically in the extremes of the distribution, with an abundance of males in the large size classes. There was no difference (p > 0.05) in carapace width between males and females in the first year, but in the second year, males were larger than females (p = 0.003), showing the importance of considering interannual variation in such studies. -

The Ohio Shrimp, Macrobrachium Ohione (Palaemonidae), in the Lower Ohio River of Illinois
Transactions of the Illinois State Academy of Science received 11/19/01 (2002), Volume 95, #1, pp. 65-66 accepted 1/2/02 The Ohio Shrimp, Macrobrachium ohione (Palaemonidae), in the Lower Ohio River of Illinois William J. Poly1 and James E. Wetzel2 1Department of Zoology and 2Fisheries and Illinois Aquaculture Center Southern Illinois University Carbondale, Illinois 62901 ABSTRACT Until about the 1930s, the Ohio shrimp, Macrobrachium ohione, was common in the Mississippi River between Chester and Cairo, and also occurred in the Ohio and lower Wabash rivers bordering southern Illinois, but since then, the species declined sharply in abundance. Two specimens were captured in May 2001 from the Ohio River at Joppa, Massac Co., Illinois, and represent the first M. ohione collected in the Ohio River in over 50 years. The Ohio shrimp, Macrobrachium ohione, was described from specimens collected in the Ohio River at Cannelton, Indiana (Smith, 1874) and occurs in the Mississippi River basin, Gulf Coast drainages, and also in some Atlantic coast drainages from Virginia to Georgia (Hedgpeth, 1949; Holthuis, 1952; Hobbs and Massmann, 1952). The Ohio shrimp formerly was abundant in the Mississippi River as far north as Chester, Illinois (and possibly St. Louis, Missouri) and in the Ohio River as far upstream as southeastern Ohio (Forbes, 1876; Hay, 1892; McCormick, 1934; Hedgpeth, 1949) but has declined in abundance drastically after the 1930s (Page, 1985). There has been only one record of the Ohio shrimp in the Wabash River bordering Illinois dated 1892, and the only record from the Ohio River of Illinois was from Shawneetown in southeastern Illinois (Hedg- peth, 1949; Page, 1985). -

Combination of questionnaire interview, focus group discussions and crosscheck interviews were accomplished with key informants during data collection. Charberjal is operated in the shoreline of rivers, submerged chars and inundated agriculture land including tiny canals all over the coastal region of Bangladesh. A total of 80 species including finfish, freshwater prawn, crabs and mollusk was recorded under 22 families including 38 SIS and 26 threatened species during the study period. The recorded species was 60 finfish, 14 prawn, 4 mollusk and 2 crabs. Among the finfish rui, bata, mullet, khorsula and poa were the dominant species while aire, boal, bacha, ramsosh and tengra were the foremost species among catfish. Moreover, Macrobrachium rosenbargii was the most prevailing species among fresh water prawn while bele, phasa, puti, shol, dimua chingri and SIS were the most leading species among others. -

Marszałka Piłsudskiego 46, PL–81–378 Gdynia, Poland; e-mail: [email protected] Received 17 January 2008, revised 30 March 2008, accepted 31 March 2008. Abstract Palaemon elegans, a new component of the Gulf of Gdańsk macrozoobenthos, colonised the southern Baltic coastal zone in the late 20th and early 21st century. Analysis of the stomach contents of P. elegans revealed 16 plant and animal taxa that these prawns had fed on. The principal dietary component was detritus, with a mean frequency of occurrence in stomachs of > 80%. The most frequently occurring plant components in the diet were algae from the genus Cladophora and the family Ectocarpaceae, while the most significant animal components were Harpacticoida, Chironomidae, Ostracoda and Gammarus spp. The results of the study show that the dietary composition of P. elegans differed significantly between stations and months. The foraging area consisted of two distinctive regions – the Inner Puck Bay, and the Outer Puck Bay together with the Dead Vistula River; two of the stations – Gdynia and Sopot – were distinct from all the others. However, no obvious seasonality in the food composition could be demonstrated. * This work was funded by a research grant N N304 264934 from the Polish Ministry of Education and Science for the period 2008–11. -
