Reproductive Aspects of Two Atyid Shrimp Caridina sakishimensis and Caridina typus in Head Water Streams of Kikai-Jima Island, Japan

Reproductive aspects of prawn Desmocaris trispinosa (Aurivillius, 1898) from a periurban stream of Abidjan (Banco stream, Côte d'Ivoire)

“…(. No significant relationship observed between the number of oocytes and the size of the shrimp (total length and carapace length), contrary to results observed in shrimp species such as Caridina sakishimensis (Fujino and Shokita, 1976) and C. typus (H. Millne Edwards, 1937) by Soomro et al (2011), and C. fossarum by Zare et al (2011).…”

Factors affecting distribution of freshwater shrimps and prawns in the Hiwasa River, southern central Japan

“…Recently recruited shrimps were excluded from individual counts for multivariate analyses, since they are undertaking upstream migration following settlement and may not be regular inhabitants of that location. Recent recruits were distinguished from adults based on the smallest sizes of over-wintered individuals in July or August described or shown in literatures (Shokita, 1979;Hamano & Hayashi, 1992;Hamano et al, 2000;Yamahira et al, 2007;Soomro et al, 2011) Hamano et al (2000). exception to the distinguishing rule was Neocaridina denticulata (De Haan, 1844), a non-diadromous species whose range within river does not change drastically throughout its life history.…”

“…Referring to results of Soomro et al (2011) on the Kikaijima Island, northern Ryukyus, and Shokita (1979), C. typus grow to 12-30 mm orbital total length (OTL) by July of the year following settlement and the majority of the recent recruits are smaller than 12 mm OTL at that point. Since C. typus has short rostrum less than 10% of its total length, we assumed that the measurement data in the present study and Soomro et al (2011) and Shokita (1979) are comparable. The population of C. typus collected in the present study (Fig.…”
