<p>ABSTRACT<br />Mudcrab is one of the fishery commodity with high economic value in Indonesia. High market and price stimulated the development of the mudcrabs business in this country. The aim of this research was to evaluate interaction between habitat characteristics and the mudcrabs (Scylla spp.) species. The research was conducted in silvofishery ponds of Eretan village, Indramayu, West Java from September-November 2013 and August-September 2014. Sampling was conducted at five stations. They were BDR (Brackishwater dominated Rhizophora sp.), BDA (Brackishwater dominated Avice

AbstractAn ecological biogeographical perspective provides an understanding of the factors that shape the geographical distribution of organisms, their biodiversity and ecological speciation. Focusing on members of the lichen genus Solenopsora, which are strongly linked to a Mediterranean-type climate, we aimed to depict their environmental niches in the Apennine Peninsula. This area represents their ecological optima, as well as the biogeographical centre of distribution. On the basis of occurrences of Solenopsora congeners, we identified the key ecological factors that shape their environmen

Ranching, stock enhancement and restocking are management approaches involving the release of wild or hatchery-bred organisms to enhance, conserve or restore fisheries. The present study, conducted from April 2002 to November 2005, evaluated the effectiveness of releasing wild and hatchery-reared (HR) mud crabs in the mangroves of Ibajay, Aklan, Philippines where preliminary studies demonstrated declining fishery yields, abundance and size of crabs. Comparison of survival and growth of wild-released and HR Scylla olivacea and HR Scylla serrata demonstrated the effect of nursery conditioning, s

The fieldworks were conducted between September and October 2024. A total of 580 Rakkang were deployed in the mangrove areas, with sample size: Rakkang-A (n = 73 lifts, 10.43±0.04) and Rakkang-B (n = 71 lifts, 10.14±2.89). The crab catch data on Scylla serrata and S. olivacea were collected, and statistical analysis was performed to determine significant differences in catch

Abstract:
Female Scylla olivacea has become more popular in Malaysia as emerging species mainly for soft-shell crabs and crab fattening (to increase weight, size and ovary maturation so that they can be sold at a higher price). To harvest crabs in soft-shell conditions and fattening, both conditions depend mostly on moulting events. To accelerate the moulting process, the manipulation of water parameter (salinity) and autotomy of the limb is commonly used. In this study, the evaluation of the moulting performances of full limb autotomy (the removal of all the appendages except for the swimming legs) and

Abstract:
Sexual dimorphism is a common phenomenon in the animal kingdom. To test the consistency of sexual dimorphism patterns among sympatric species of the same genus, ten morphometric characteristics of mud crabs Scylla olivacea, S. tranquebarica and S. paramamosain were measured and compared using Discriminant Function Analysis (DFA). The descriptive analysis revealed that in all three species, body size dimensions and cheliped dimensions were significantly larger in males whereas the abdomen width was female-biased. Also, we described a morphological variation (carapace width, CW ≤ CW at spine 8,

This study describes the morphological and histological characteristics of the male reproductive system of the orange mud crab, Scylla olivacea (Herbst, 1796). Three maturation stages were determined on the basis of the vas deferens diameter, the gonad colour and the gonadosomatic index (GSI). Significant differences were observed in the GSI value as the crabs matured. All germ cells were present in the histological sections of the testes, and these decrease significantly in size as they progress from spermatogonia, spermatocytes, and spermatids to spermatozoa. Spermatophores are found in the

A seleção de indivíduos dentro de uma população de determinada espécie é um processo crucial para estimar dados ecológicos, como densidade populacional, padrões comportamentais ou sobrevivência. Métodos de Captura-Marcação-Recaptura (CMR) consistem na marcação de indivíduos e têm sido utilizados para monitorizar espécies elusivas, como é o caso da megafauna marinha. As tartarugas-marinhas são répteis que possuem uma elevada longevidade e grande parte do seu ciclo de vida é efetuado no mar.
