  • Effect of Feed on the Growth and Survival of Long Eyed Swimming
    Soundarapandian et al., 2:3 http://dx.doi.org/10.4172/scientificreports681 Open Access Open Access Scientific Reports Scientific Reports Research Article OpenOpen Access Access Effect of Feed on the Growth and Survival of Long Eyed Swimming Crab Podophthalmus vigil Fabricius (Crustacea: Decapoda) Soundarapandian P1*, Ravichandran S2 and Varadharajan D1 1Faculty of Marine Sciences, Centre of Advanced Study in Marine Biology, Annamalai University, Tamil Nadu, India 2Department of Zoology, Government Arts College, Kumbakonam, Tamil Nadu, India Abstract Food is considered to be the most potent factor affecting growth. Attempts to develop diets for culture of crabs have resulted in a variety of feeds. The absence of suitable feed either pellet or live food which can promote growth and survival is considered to be the most important lacuna in cultivation of crabs. So searching of economically viable feed to optimize the growth and survival in crabs are very much essential. In the present study the weight gain was higher in the crabs offered with Acetes sp. (86 g) followed by clam meat fed animals (47 g). The crabs fed with minimum amount of Acetes sp. (152 g) and maximum of clam meat (182 g). The FCR value was better in Acetes sp. (1.8) fed animal rather than clam meat fed animals (3.8). The survival rate was higher in Acetes sp. fed animals (92%) and lowest survival (72%) was observed in animals fed with clam meat. The survival was reasonable for both the feeds. But higher survival rate was reported in the animals fed with Acetes sp. than that of clam meat.

  • Diversity and Abundance of Intertidal Crabs at the East Swamp- Managed Areas in Segara-Anakan Cilacap, Central Java, Indonesia
    Deutscher Tropentag, October 8-10, 2003, Göttingen “Technological and Institutional Innovations for Sustainable Rural Development” Diversity and Abundance of Intertidal Crabs at the East Swamp- Managed Areas in Segara-Anakan Cilacap, Central Java, Indonesia 1 2 2 MOH.

The conservation of mangrove forests into prawn ponds causes depletion of supply of river sediments and loss of property. The main objective of this study is to compare the diversity and abundance of intertidal crabs in undisturbed, crab hunting, logging and prawn pond areas that were different in percent mangrove canopy covers and percent sediment textures. In each area, two transect lines were installed to analyse the percent mangrove canopy cover, and also the percent sediment texture comparing to trilinier plot. In total, 16,353 intertidal crab individuals in 13 species were sampled. Differences in observed number and estimated number of species (ACE, Chao1), as well as number of individuals, diversity indices and evenness between the four studied mangrove areas were all highly significant. Monthly fluctuation of intertidal crab diversity was more constant in the undisturbed area with a high mangrove coverage (90%) compared to the crab hunting, the logging and the prawn pond area with a coverage of 89%, 33% and 0%, respectively.

  • Rearing Enhancement of Ovalipes Trimaculatus (Crustacea: Portunidae
    www.nature.com/scientificreports OPEN Rearing enhancement of Ovalipes trimaculatus (Crustacea: Portunidae) zoea I by feeding on Artemia persimilis nauplii enriched with alternative microalgal diets Antonela Martelli1,3*, Elena S. Barbieri1,3, Jimena B. Dima2 & Pedro J. Barón1 The southern surf crab Ovalipes trimaculatus (de Haan, 1833) presents a high potential for aquaculture. In this study, we analyze the benefts of diferent dietary treatments on its molt success and ftness of larval stages. Artemia persimilis nauplii were enriched with monospecifc (Nannochloropsis oculata, Tetraselmis suecica, Dunaliella salina, Isochrysis galbana and Chaetoceros gracilis) and multispecifc (Mix) microalgal diets twice a day over a 48-h period. Mean total length (TL), growth instar number (I) and gut fullness rate (GFR) of nauplii showed signifcant diferences between dietary treatments at several sampling times, optimal results being observed in those providing Mix. Artemia nauplii grown under most experimental dietary treatments reached the capture size limit for Ovalipes trimaculatus zoea I (700 µm) within 24 h. After that time interval, Mix-enriched nauplii were amongst those with higher protein contents. Ovalipes trimaculatus zoea I fed on Artemia nauplii enriched during 24 h under diferent dietary treatments showed signifcant diferences in survival, inter-molt duration, molting success to zoea II and motility. Optimal results were observed in zoea I fed on Mix-enriched Artemia nauplii. This work not only represents a frst step towards the dietary optimization for O. trimaculatus zoeae rearing but also provides the frst results on the use of enriched A. persimilis. Portunid crabs stand out as highly valued resources for fsheries and aquaculture because of their export potential and high nutritional value1.

  • A New Pathogenic Virus in the Caribbean Spiny Lobster Panulirus Argus from the Florida Keys
    DISEASES OF AQUATIC ORGANISMS Vol. 59: 109–118, 2004 Published May 5 Dis Aquat Org A new pathogenic virus in the Caribbean spiny lobster Panulirus argus from the Florida Keys Jeffrey D. Shields1,*, Donald C. Behringer Jr2 1Virginia Institute of Marine Science, The College of William & Mary, Gloucester Point, Virginia 23062, USA 2Department of Biological Sciences, Old Dominion University, Norfolk, Virginia 23529, USA ABSTRACT: A pathogenic virus was diagnosed from juvenile Caribbean spiny lobsters Panulirus argus from the Florida Keys. Moribund lobsters had characteristically milky hemolymph that did not clot. Altered hyalinocytes and semigranulocytes, but not granulocytes, were observed with light microscopy. Infected hemocytes had emarginated, condensed chromatin, hypertrophied nuclei and faint eosinophilic Cowdry-type-A inclusions. In some cases, infected cells were observed in soft con- nective tissues. With electron microscopy, unenveloped, nonoccluded, icosahedral virions (182 ± 9 nm SD) were diffusely spread around the inner periphery of the nuclear envelope. Virions also occurred in loose aggregates in the cytoplasm or were free in the hemolymph. Assembly of the nucleocapsid occurred entirely within the nucleus of the infected cells. Within the virogenic stroma, blunt rod-like structures or whorls of electron-dense granular material were apparently associated with viral assembly. The prevalence of overt infections, defined as lethargic animals with milky hemolymph, ranged from 6 to 8% with certain foci reaching prevalences of 37%. The disease was transmissible to uninfected lobsters using inoculations of raw hemolymph from infected animals. Inoculated animals became moribund 5 to 7 d before dying and they began dying after 30 to 80 d post-exposure.

  • Evaluation of Selected Commercial Aquaculture Feeds As Substitute for Natural Feeds in Rearing Mud Crab (Scylla Serrata) Juveniles Jerome G
    Evaluation of selected commercial aquaculture feeds as substitute for natural feeds in rearing mud crab (Scylla serrata) juveniles Jerome G. Genodepa, Alan N. Failaman Institute of Aquaculture, College of Fisheries and Ocean Sciences, University of the Philippines Visayas, Miag-ao, Iloilo 5023, Philippines. Corresponding author: J. Genodepa, [email protected] Abstract. A feeding trial was conducted to assess the potential of commercial feeds for fish and shrimp as substitute for natural feeds in rearing juveniles of the mud crab, Scylla serrata. The crablets (2nd crab instar; 0.044 to 0.049 g average body weight (ABW); n = 300) were fed either fish feed, shrimp feed or natural feeds (mussel and Acetes) alone, or with the 50-50% combination of the natural feed and each of the commercial feeds. The performance of the feeds and their combinations were evaluated after 11 and 20 days of rearing in 1000 L tanks based on survival, ABW, specific growth rate (SGR) and degree of aggression (indicated by missing appendages). The commercial diets tested were not suitable as complete replacement for natural feeds in rearing mud crab juveniles. Treatments fed with the commercial diets had significantly lower survival (35 to 54%) and ABW (0.186 to 0.399 g) compared to the treatment fed natural feeds alone (74% survival and 0.506 g ABW) after 20 days (p < 0.01). The combination of commercial feeds and natural feeds can possibly replace natural feeds during nursery rearing of juvenile crabs. The ABW in the treatment fed the combination of shrimp feed and natural feeds (0.611 g) was significantly higher (p < 0.01) than the treatment fed natural feeds only (0.506 g) while it did not differ between the treatment fed natural feeds only and the combination of fish feed and natural feeds (0.535g).

  • Temperature Potentially Induced Distinctive Flavor of Mud Crab Scylla Paramamosain Mediated by Gut Microbiota
    www.nature.com/scientificreports OPEN Temperature potentially induced distinctive favor of mud crab Scylla paramamosain mediated by gut microbiota Lei Tang1, Huan Wang 1,2*, Chunlin Wang1,2, Changkao Mu1,2, Hongling Wei1, Hongzhi Yao1, Chunyu Ye3,4, Lizhi Chen3,4 & Ce Shi1,2 Many factors afect the favor of crabs. However, impact of temperature on favor has not been reported. Here, we examined Scylla paramamosain collected within the main four producing areas in China from north sampling point (NP) and south sampling point (SP), respectively. The contents of favouring-related substances in hepatopancreas, muscles and gonads were determined by high- performance liquid chromatography (HPLC). Meanwhile, high-throughput sequencing of 16S RNA gene was used to reveal the diversity distribution of gut microbiota at each sample collection point. Comparisons among favor substances of edible parts, the implied higher temperature in SP may be benefcial to the accumulation of favor substances in gonads, while lower temperature in NP may be benefcial to the accumulation of favor substances in muscles and hepatopancreas. The gut microbiota of crabs, was analyzed via 16S rRNA gene sequencing. The results of gut microbiota showed that there were signifcant diferences in the distribution of gut microbiota in NP and SP. The microbiota composition of SP has a high distribution richness and no absolute dominant bacteria, while NP has absolute dominant bacteria and its microbiota richness was lower than SP. The results of redundancy analysis (RDA) showed that there was a signifcant correlation between temperature and the relative abundance of gut microbiota, and a signifcant correlation between gut microbiota and the content of favor substances.
