A new species of Tigriopus (Copepoda, Harpacticoida, Harpacticidae) from Thailand with the description of its naupliar development

Abstract

Both genders of Tigriopus thailandensis sp. nov. are described from a laboratory stock raised from individuals collected from the seaweed Enteromorpha clathrata in Thailand (Bangsaen Beach, Chonburi Province). Tigriopus thailandensis sp. nov. shares with its closest relative T. japonicus Mori, 1932 two setae on the third exopodal segment of leg 4 while other congeners bear 3 inner setae. However, allobasis and exopod of antenna in both genders are much more slender and elongate than in T. japonicus. All six naupliar stages of T. thailandensis are described from the offspring of isolated females. In comparison with nauplii of T. japonicus, T. thailandensis nauplii are characterized by the following: a smaller body size throughout the naupliar phase; first antennular segment without seta, second antennular segment with only one small seta plus two longer setae; third antennular segment with additional spinules from naupliar stage II onwards; antenna bears three small spinules on the terminal exopodal segment; one additional seta on the anterior surface of the antennary basis, tubular endopod of antenna with one tiny seta midlength at naupliar stage III that increases in size; mandibular basis with several spinules on anterior surface; mandibular coxa with one spinulose seta that is smooth in T. japonicus.

Improvement of copepod nutritional quality as live food for aquaculture: a review

“…As the expansion of mariculture has become increasingly important as a means to meet the protein supply for human consumption, the development of novel technologies for fish farming is urgently needed (Camus & Zeng ; Chullasorn, Ivanenko, Dahms, Kangtia & Yang ). In aquaculture hatcheries, the use of live food is essential for successful larval fish rearing.…”

Range‐wide phylogeography and taxonomy of the marine rock pools dwellerTigriopus fulvus(Fischer, 1860) (Copepoda, Harpacticoida)

“…In the Atlantic–Mediterranean area (i.e., the Mediterranean Sea and the Eastern Atlantic Ocean south to the Tropic of Cancer), three Tigriopus species are to date allegedly reported to occur: Tigriopus fulvus , T. brevicornis , and T. brachydactylus Candeias, 1959. However, T. brachydactylus was actually erroneously reported to occur in Northern Europe by Chullasorn et al (2011) and Chullasorn et al (2013), whereas, as already evidenced by Park et al (2014), the species was originally described from Angola (western coast of Southern Africa) and never reported for European coasts. Moreover, T. minutus Božić, 1960 was described just south of our study area, and reported to occur in Senegal (Božić, 1960).…”
