A.G.J. A distinct oval dark brown tympanic spot present above pectoral fin. A large tympanic spot present above the pectoral fin. All 16 characters (including length and width of transverse processes of dorsal transverse bar) measured on each of the 07 samples were normally distributed. According to McConnel (1975), mystids in African lakes are carnivores in general. Bamboo chicken, bamboo shoots, bini rice, nappi (fermented fish paste), shidal (fermented fish sauce) mochi (smoked curry), and chelay (fermented beverage) are some of their favorite foods and local drinks. Changing conditions can change feeding dynamics (Le Bail and Boeuf, 1997). )); Turtles (one reported species, soft-shell turtle (Trionyx sinensis)); Sea squirts and other tunicates (one reported species, red bait (Pyura stolonifera)); Sea urchins and other echinoderms (one reported species, sea urchin (Strongylocentrotus spp.)). Surprisingly, there had possibly been no mortalities among L. rohita, C. catla, and C. mrigala—although they became infected, no mortality was said to have been observed, as reported by Anon (1998): “Epizootic Ulcerative Syndrome (EUS) in Fishes of Pakistan: A report regarding visit of Mission to Punjab in connection with Epizootic Ulcerative Syndrome (EUS),” April 22–25, 1998. 144 Mystus tengara, RGUMF-104, 57.0 mm SL: lateral view.

Modeling of environmental parameters in an ecological framework has provided valuable insight into the role of osmoregulation in bluegill (Lepomis macrochirus) (Neill et al., 2004), red drum (Sciaenops ocellatus) (Fontaine et al., 2007), and juvenile sole (Solea solea) (Fonseca et al., 2010). Further, as reported by a number of other workers and mentioned earlier in this treatise, EUS is said to be caused by a fungus called A. invadans. The outbreaks had usually occurred between June and December, predominantly during the postmonsoon months. Further, treatment with a GnRH analog increases plasma T3 levels but not T4 in immature rainbow trout (Plate et al., 2002). No lateral longitudinal band, presence of a dark brown nuchal (in front of dorsal fin) and a humeral (above the pectoral fin) spots .........................................................................M. cavasius, 2b. India is one of the megabiodiverse countries in the world and occupies ninth position in terms of FW megabiodiversity (Mittermeier and Mittermeier, 1997). Economic importance: Used as food fish. The energy cost of osmoregulation in different salinities may be relatively modest in teleosts (Boeuf and Payan, 2001) but can be significant when salinity shifts rapidly (Du Preez et al., 1990; Morgan et al., 1997; Morgan and Iwama, 1999).

Harvesting and marketing: Dip net (dharma jal), Push net (thela jal), wucha (bamboo trap) used for fishing (Bhuiyan, 1964). 101–104). It is important to have scientific knowledge about the nature of fish ... Chanda nama, Chanda ranga, Rita rita, Glossogobious giuris, Mystus seenghala, Mystus cavassius, Ompok pabda, etc. Coloration. Earlier records of Mystus vittatus from Arunachal Pradesh (e.g., Bagra et al., 2009; Gurumayum et al., 2016) are probably due to misidentification of M. tengara or M. carcio. The three broad stripes: dorsal, midlateral, and ventrolateral, are separated by narrow pale interspace. The coastal and marine zone of Bangladesh is one of the world's wealthiest ecosystems having higher productivity and unique mangrove influences. RGUMF-375, 10 exs., 57.9–80.4 mm SL, Sinkin River at Anpum, a tributary of Siang River, Lower Dibang Valley district, AP. INTRODUCTION Fishes form one of the most important groups of vertebrates, influencing the aquatic ecosystem & life in various ways. But in the next year export quantity and earnings of the country's decreased, reached at 84904.5 metric tons (534.92 million USD). S. M. Nazmul Alam, M. Niamul Naser, in Nutritional and Health Aspects of Food in South Asian Countries, 2020. The 207 different animal and plant species currently cultivated on a global basis are listed in the following sections. Observed patterns diverge from this construct, varying with species, ontogeny, and season (Gutt, 1985; Morgan and Iwama, 1991; Lambert et al., 1994; Deacon and Hecht, 1999). Materials examined. ), blood cockle (Anadara granosa), northern quahog (Mercenaria mercenaria), inflated ark (Scapharca broughtonil), pullet carpet shell (Tapes pullastra), groved carpet shell (Ruditapes decussatus), common edible cockle (Cardium edule), butter clam (Saxidomus giganteus), donax clams (Donax spp), Pacific littleneck clam (Prothaca staminea), striped venus (Venus gallina)); Squids, cuttlefishes, octopuses (two reported species, including octopuses (Octopus spp. The fisheries sector plays a vital role in the national economy, having a share in GDP of about 3.61%. Inland aquaculture of indigenous and exotic carp species, as well as tilapia, pangas, koi, mola, has expanded massively. For the ayu high salinity results in the acceleration of yolk depletion and reduced growth (Iguchi and Takeshima, 2011). Fig. However, plasma TH levels are unchanged with salmon GnRH treatment of goldfish, and salmon GTH does not alter secretion of T4 in medaka (Cyr & Eales, 1996).
