1. Appropriate food type, feeding schedule and Artemia density for the zoea larvae of the mud crab, Scylla tranquebarica (Crustacea:Decapoda:Portunidae)

Author:
Baylon, Juliana C.

Aquaculture 2009 v.288 no.3-4 pp. 190-195
ISSN:
0044-8486
Subject:
Portunidae; crabs; crab culture; mortality; animal development; metamorphosis; animal feeding; live feeds; Rotifera; Artemia
Abstract:
... Scylla tranquebarica is an edible portunid crab with high commercial value. To develop hatchery techniques for juvenile production, the feeding requirements of the larvae were investigated. Experiments were carried out to identify food preferences, feeding schedule and optimum prey density. Larval diets of rotifer Brachionus sp, brine shrimp Artemia sp nauplii, and a combination of both were provi ...

Brachionus; Chlamydomonas; alpha-linolenic acid; carbon; diet; ecophysiology; eicosapentaenoic acid; fatty acid composition; glucose; omega-3 fatty acids
Abstract:
... 1. We examined an important ecophysiological link between the mixotrophic flagellate Chlamydomonas acidophila and its consumers, the rotifers Elosa worallii, Cephalodella sp. and Brachionus sericus, by comparing their fatty acid profiles. 2. The mixotrophic flagellate was grown under either exclusively autotrophic conditions in the light, under exclusively heterotrophic conditions in the dark with ...

Brachionus; DNA; biotypes; cytochrome-c oxidase; genetic polymorphism; hatcheries; polymerase chain reaction; rapid methods; Nevada
Abstract:
... Cryptic species are increasingly being recognized in many organisms. In Brachionus rotifers, many morphologically similar yet genetically distinct species/biotypes have been described. A number of Brachionus cryptic species have been recognized among hatchery strains. In this study, we present a simple, one-step genetic method to detect the presence of those Brachionus sp. rotifers that have been ...

Abstract:
... Old Fort Lake, a small (1.6 ha), shallow, and recreational water body in Delhi (India) was studied through monthly surveys in two consecutive years (January, 2000-December, 2001). Precipitation is the major source of water for this closed basin lake. In addition, ground water is used for replenishing the lake regularly. This alkaline, hyposaline hard water lake contains very high ionic concentrati ...

Abstract:
... We attempt to ascertain the selection mechanisms that affect algal species' abilities to thrive in a given environment, and how the variability of the response is reflected in the community structure (total biomass, diversity) and also in community function (photosynthesis and respiration). For that, we formed algal communities, assembling eight species of freshwater cosmopolite algae with distinc ...

6. Role of abiotic and biotic factors in structuring the metazoan plankton community in a lowland river

Abstract:
... Water and quantitative zooplankton samples were collected at approximately monthly intervals from June 2000 to June 2002 in the middle section of the Po River (Northern Italy). Highly variable hydrological conditions were observed in the 2 years, with river flow varying approximately between 400 and 9300 m³ s⁻¹. Dissolved inorganic nitrogen (DIN) usually decreased at higher river discharges. Autot ...

Abstract:
... We examined the temporal and vertical dynamics of zooplankton in Weavers Lake, New Zealand, between October 2004 and October 2005, at a time when it was colonised by a non-indigenous Daphnia species. Zooplankton community composition changed during the study from one of rotifer dominance (e.g. Asplanchna, Polyarthra, Brachionus and Keratella species) to cladoceran (Daphnia dentifera) dominance. Te ...
