Analysis of Fishery and Stock of the Portunid Crab, Charybdis Feriata (Linnaeus, 1758) from Veraval Waters, North-West Coast of India
Indian J. Fish., 61(4) : 1-9, 2014 1 Analysis of fishery and stock of the portunid crab, Charybdis feriata (Linnaeus, 1758) from Veraval waters, north-west coast of India GYANARANJAN DASH, SWATIPRIYANKA SEN, K. MOHAMMED KOYA, K. R. SREENATH R. THANGAVELU, SURESH KUMAR MOJJADA AND M. S. ZALA Veraval Regional Centre of Central Marine Fisheries Research Institute, Matsya Bhavan, Bhidia, Veraval - 362 269 Gujarat, India e-mail: [email protected] ABSTRACT Fishery and stock characteristics of the portunid cab Charybdis feriata from the waters off the north-west coast of India was studied based on commercial trawl landings at Veraval during 2009-2011. Growth parameters L∞, K and -1 -1 t0 were estimated as 171.5 mm, 0.97 yr and -0.10 yr respectively. Mortality parameters Z, M and F were 3.97 yr , -1 -1 1.49 yr and 2.48 yr respectively. The length at capture (L50) and length at maturity (LM50) were 95.4 mm and 87.3 mm, respectively which indicates that crabs enter into peak exploitation phase after attaining sexual maturity. The bio-economic stock assessment model showed that the species can be exploited at the present fishing level to maintain the economy of the fishery at maximum level (MEY) or the effort can be increased by 2.4 times to maximise the yield (MSY) depending upon the management objective. However, since the stock recruitment relationship is not defined, as a precautionary approach, the effort should not be increased more than 1.3 times the present level to conserve the spawning stock.

Charybdis hellerii is a potential threat to native crab populations and benthic communities and its introduction should be avoided by adhering to ballast water management guidelines. view this species on IUCN Red List Species Description Charybdis hellerii is a small crab measuring from about 5-8 cm wide. It is dark green with a light purple on the upper inner surface of palm and dark purple on dorsal surfaces of distal 4 segments of walking and swimming legs. The carapace has pale green to whitish areas on frontal, hepatic, and epibranchial regions. It is most easily identifiable by the spine on the posterior of the carpus on the fifth leg which bears its chela, or claws giving it one of its common names: spiny hands. Its dorsal carapace is naked and its anterolateral margin has 6 prominent black-tipped teeth. -

Box 8030, HaiJa 31080, Israel (Accepted8 May 1998) A significant portion of the population of Charybdis longicollis (Decapoda: Portunidae) along the Mediterranean coast of Israel is parasitized by the rhizo- cephalan Heterosaccusdollfusi. The behaviour of the parasitized crabs, in different stages of infection, is examined and compared with the behaviour of non- parasitized crabs. Locomotion, rest, body-, egg- and parasite-grooming,digging and burying, courtship and mating are described qualitatively and analysed quantitatively under standardized conditions. Behaviour patterns of parasitized crabs lacking externae,either immature or scarred,were similar to those of non- parasitized crabs. The presenceof externae was observedto modify digging and to inhibit burying behaviour. The presenceof externae induces an imitation of egg-grooming behaviour pattern in both males and females. Exlernae-bearing crabs engagedin parasite-groomingmore intensely than ovigerous crabs in egg- grooming. Ksvwono s: Charyhdis, H et er osac cus, Rhizocephala, parasitism, behaviour. Introduction The lessepsian portunid crab Charybdis longicollis Leene is one of the most common decapods along the Mediterranean coast of Israel, where it was first recorded about 40 years ago (Lewinsohn and Holthuis, 1964). Since 1993, it has been parasitized by the rhizocephalan Heterosaccusdollfusi Boschma, a lessepsian migrant too (Galil and Litzen, 1995). H. dollfusi penetrates through the gills of young C. -

Over 10,500 names are treated including 6,793 valid species and subspecies (with 1,907 primary synonyms), 1,271 genera and subgenera (with 393 primary synonyms), 93 families and 38 superfamilies. Nomenclatural and taxonomic problems are reviewed in detail, and many resolved. Detailed notes and references are provided where necessary. The constitution of a large number of families and superfamilies is discussed in detail, with the positions of some taxa rearranged in an attempt to form a stable base for future taxonomic studies. This is the first time the nomenclature of any large group of decapod crustaceans has been examined in such detail.

Legs laterally flattened to varying degrees, last 2 segments of last pair paddle-like. Male abdominal segments 3 to 5 completely fused, immovable. anterolateral margin with 5-9 teeth 5 segments 4 3-5 fused, immovable 3 male abdomen sedments 3-5 immovable male abdomen last pair of legs paddle-like Habitat, biology, and fisheries: Benthic to semipelagic crabs with diverse habits. Many species of great fishery value, notably Scylla serrata, Portunus pelagicus, P. sanguinolentus, P. trituberculatus, and Charybdis feriatus. Similar families occurring in the area Portunids may be confused with spanner crabs (Raninidae) and moon crabs (Calappidae: Matutinae), which also possess paddle-like legs. They can be separated from portunids as follows: Raninidae: carapace usually longitudinally ovate; sternum very narrow; fingers of chela strongly bent; meri of third maxillipeds triangular (quadrate in portunids). Calappidae (subfamily Matutinae): carapace circular to subcircular; at least last 3 pairs of legs paddle-like, (not only the last pair); meri of third maxillipeds triangular in cross-section (quadrate in portunids). fingers strongly bent Calappidae (subfamily Matutinae) carapace all legs longitudinally ovate paddle-like Raninidae 1116 Crabs Key to species of interest to fisheries occurring in the area 1a.

SciENTiA M arina71(2) June 2007, 287-292, Barcelona (Spain) ISSN: 0214-8358 Decapod crustaceans associated with the snakelock an em on eAnemonia sulcata. Living there or just passing by? RICARDO CALADO, GISELA DIONÍSIO and MARIA TERESA DINIS CCMAR Universidade do Algarve, Campus de Gambelas, 8000-117 Faro, Portugal. E-mail: [email protected] SUMMARY: The present work identifies the decapod crustaceans that associate with Anemonia sulcata on the southwest ern Atlantic coast of Portugal and characterises their host use pattern. It determines whether the anemone is monopolised by any species, resulting in the exclusion of conspecifics or other decapods and, under laboratory conditions, it evaluates the degree of association between each species and A. sulcata. From all sampled anemones, 79% harboured at least 1 decapod crustacean, with the majority displaying either one or two specimens (32 and 24%, respectively). The most abundant species were the shrimp Periclimenes sagittifer and the crab Inachus phalangium (representing 36 and 31% of collected specimens, respectively), which displayed lasting associations and were commonly recorded among the tentacles of the host. The species Eualus occultus. complexE. cranchii. Clibanarius erythropus. Maja brachydactyla. Pilumnus and hirtellusPolybius (Necora) puber displayed short-term associations, were mainly present on the substratum near the base, and avoided the ten tacles of A. sulcata. Periclimenes sagittifer and I. phalangium were only recorded alone or in heterosexual pairs, appearing to efficiently defend their host against conspecifics. The majority of recorded species only seem to temporarily associate with A. sulcata, in order to seek protection from predators when other shelters are unavailable. Keywords'. Anemonia sulcata, associative behaviour, decapod crustaceans. -
