The distribution of freshwater shrimps (Atyidae and Palaemonidae) in Jamaica
Zoological Journal of the Linnean Society, 1978The distribution of freshwater shrimps in Jamaica is presented. Atya innocous, Atya lanipes, Atya scabra, Micratya poeyi and Macrobrachium heterochirus were found only in the high-gradient streams characteristic of eastern and north-eastern parishes.

Thermal tolerance and preference of the freshwater shrimp Palaemonetes kadiakensis
Journal of Thermal Biology, 1982Abstract 1. 1.|Freshwater shrimp, acclimated to a fluctuating room temperature regime (20–28°C) and five different constant temperatures (24, 26, 28, 30 and 32°C), were tested to characterize their upper tolerance limits and to assess their abilities to thermoregulate behaviourally within a horizontal thermal gradient. 2.

Embryology of African giant freshwater shrimp Macrobrachium vollenhovenii
Biologia, 2019The current study aimed to describe the embryonic development of Macrobrachium vollenhovenii. Male and female begetters were captured from the coastal lagoon of Grand-Popo and then reared in a pond. At total 83,323 eggs were spawned by the chosen female (weighting 60.51 g and measuring 153 mm) with an average fecundity rate of 81.6%.

Characterization of the complete mitogenome for the freshwater shrimp Exopalaemon modestus
Conservation Genetics Resources, 2017Natural resources of the freshwater shrimp Exopalaemon modestus declined sharply in China in recent years. However, available genetic information for this shrimp is quite limited presently. In this study, the complete mitochondrial genome of E. modestus was firstly determined through Illumina sequencing. The mitogenome is 15,736 bp in length containing

The freshwater shrimps of the family Atyidae (Decapoda, Caridea) of Thailand
CrustaceanaAbstract The Thai freshwater shrimps of the family Atyidae are reviewed. A taxonomic synopsis is given here to the 19 species so far known from Thailand, including two new species, namely Caridina thai sp. nov. and C. kottelati sp. nov. Two species are recorded for the first time from Thailand, namely C. annandalei, and C. rangoona.

Studies on Vitellin Accumulation in Freshwater Shrimp, Palaemon paucidens
広島大学生物生産学部紀要, 1989スジエビの卵黄形成過程を成長期、卵黄形成前期、卵黄形成後期に分類し、ポリアクリルアミド濃度勾配ゲル電気泳動法、免疫学的方法で卵黄物質の蓄櫓機構を調べた。1)成長期の卵黄は卵巣指数(GSI)約1.5以下、最大卵径(MED)300μm前後以下で、卵母細胞はヘマトキシリンで染色される核と細胞質を有する。この段階の親の血リンパ中には免疫学的に卵巣ビテリンと同一の成分は検出されなかった。2)卵黄形成前期の卵巣はGSI1.5から4.5、MED250から550μmに相当し、卵細胞内に核を有し細胞質は増大してエオシン好染性に変じ、卵黄顆粒が出現し始めた。MED350μm以上の卵細胞を持つ親の血リンパには免疫学的にビテリンと同一のリポタンパク質が出現した。3)GSI4.5以上 ...
