Growth, Life History, and Respiration of Mysis relicta in an Arctic and Temperate Lake

Abstract

Mysis relicta from Char Lake (N.W.T.) take 2 years to reach maturity, retaining 36 cal as net production; those from Stony Lake (southern Ontario) mature in 1 year, retaining 53 cal as net production. Growth rates were highest during summer months for individuals in both lakes. Results of respiration experiments at 0, 2, 4, 6, and 8 C for Char Lake mysids and at 2, 4, 7, 10, and 13 C for Stony Lake mysids were not significantly different, indicating that Mysis relicta demonstrates no metabolic compensation over its environmental temperature range. Generalized energy budgets were constructed for individuals from each population for their entire life-span. A female uses approximately 209 cal for growth and respiration to become a reproducing adult in one year in Stony Lake and approximately 206 cal to become a reproducing adult in 2 years in Char Lake.

Seasonality, reproductive biology and ecology of Mesopodopsis zeylanica (Crustacea: Mysida) from a tropical estuary (Cochin backwater) in India

“…In mysids, the shortest duration (4 days) of marsupial development is reported for M. orientalis, while the developmental time of its European congener Mesopodopsis slabberi (Van Beneden) was 9 to 19 days (Greenwood et al 1989). Mysis relicta Loven, a coldwater species, has the longest (240 days) reported development time (Lasenby & Langford 1972). In Cochin backwater, M. zeylanica reproduces all year round.…”

Allometric constraints and variables of reproductive effort in brachyuran crabs

“…However, other crustacean groups exhibit significant intraspecific variation in the components of reproductive effort with respect to (1) geographic location, especially latitude: mole crabs (Hippidae) (Efford, 1969), stomatopods (Reaka, 1979), barnacles (e.g. Barnes, 1965, 1968), copepods (McLaren et al, 1969), mysids (Lasenby and Langford, 1972), lobsters (Morizur et al, 1981), and amphipods (Steele and Steele, 1975 b); (2) season: mole crabs (Diaz, 1980) and cumaceans (Corey, 1981); (3) tidal height: barnacles (e.g. Barnes and Barnes, 1968) and copepods (Palmer, 1980); and (4) limiting resources: hermit crabs (Bertness, 1981).…”

Biometrical relationships, energy content and biochemical composition of Neomysis mercedis from Lake Washington

“…These relationships can be used to compute secondary production in order to analyze energy flow through the ecosystem . Regression equations of biometrical relationships have been published for a number of mysid species, including Mysis relicta Loven (Lasenby & Langford, 1972 ;Reynolds & De Graeve, 1972), Neomysis mirabilis Czerniavsky (Shushkina et al ., 1971), N. japonica Nakazawa (Uye, 1982), N. integer Leach (Jensen, 1985), M. mixta Lilljeborg (Rudstam et al ., 1986 ;Wiktor & Szaniawska, 1988 ; see also the review by Mauchline, 1980) . Proximate analyses of biochemical composition have also been made for a few mysid species, especially those living in estuarine and marine systems (Mauchline, 1980 ;Raymond et al ., 1964Raymond et al ., , 1968) .…”
