“…We tested A. balloti in August, during the Australian winter and after spawning. Even during this period of relatively low natural responsiveness (Himmelman et al, 2009), A. balloti showed more phasic activity than the other species. Placopecten magellanicus and P. fumatus were next in sequence for high phasic activity.…”

“…Amusium balloti is unusual, compared with other scallops, as it reacts very strongly to crustaceans. Of a suite of potential predators including crustaceans and a sea star, T. orientalis elicited the strongest escape response from A. balloti (Himmelman et al, 2009). Thenus orientalis can suddenly extend its tail to lunge forward to seize its prey at a distance of 30-50cm (Jones, 2007).…”

SUMMARYThe simple locomotor system of scallops facilitates the study of muscle use during locomotion. We compared five species of scallops with different shell morphologies to see whether shell morphology and muscle use change in parallel or whether muscle use can compensate for morphological constraints. Force recordings during escape responses revealed that the use of tonic and phasic contractions varied markedly among species. The active species, Amusium balloti, Placopecten magellanicus and Pecten fumatus, made more phasic contractions than the more sedentary species, Mimachlamys asperrima and Crassadoma gigantea. Tonic contractions varied considerably among these species, with the two more sedentary species often starting their response to the predator with a tonic contraction and the more active species using shorter tonic contractions between series of phasic contractions. Placopecten magellanicus made extensive use of short tonic contractions. Pecten fumatus mounted an intense series of phasic contractions at the start of its response, perhaps to overcome the constraints of its unfavourable shell morphology. Valve closure by the more sedentary species suggests that their shell morphology protects them against predation, whereas swimming by the more active species relies upon intense phasic contractions together with favourable shell characteristics.

“…Makanan disaring melalui silia dan insang dengan jenis makanan terdiri atas aneka plankton dan endapan detritus yang berukuran kurang dari satu mikron. Menurut Joll (1989) dalam Himmelman et al (2009), kerang dari genus Amusium mempunyai kemampuan berenang paling baik di antara jenis kerang lainnya. Jenis Amusium balloti secara individu mampu berenang sampai 23 m menuju permukaan.…”

ABSTRAKKerang simping (Amusium pleuronectes) yang secara taksonomis termasuk famili Pectinidae adalah salah satu jenis kerang ekonomis penting di Laut Jawa. Tujuan dari penelitian ini adalah untuk mendapatkan data dan informasi mengenai kepadatan stok, sebaran panjang, dan hubungan panjang bobot kerang simping. Data 31-40 m (2008) and 0.36 kgs/hour in depth 11-20 m (2009) . From the overall length frequency distribution it is likely that the population of the asia moon scallop consisted of one strong cohort, with the modus of 54 mm. From the cumulative percent frequencies distribution it was also observed that 50% of the distribution can be assummed as equal to the length of first capture, L c = 52 mm. Length weight analysis indicated that b isometry. KEYWORDS:Asia moon scallop, stock density, biological aspect, Tegal waters PEDAHULUANKerang simping jenis Amusium pleuronectes adalah salah satu jenis kerang yang memiliki nilai ekonomis cukup penting. Simping hidup di daerah sublitoral kedalaman antara 10-80 m, dengan dasar perairan pasir lumpur. Amusium pleuronectes tersebar dari mulai perairan Myanmar, Indonesia, sampai Papua New Guini; perairan utara Taiwan, Jepang, sampai Queensland (Food and Agriculture Organization,1998). Kerang simping cukup menyebar di perairan Indonesia namun belum semua daerah memproduksi atau mencatatnya. Penangkapan kerang simping di Indonesia dilakukan dengan alat tangkap modifikasi dari trawl yang disebut dengan arad . Seperti halnya hasil penelitian di Tegal dan sekitarnya, simping banyak tertangkap oleh jaring arad sebagai hasil tangkapan sampingan. Secara taksonomis, simping termasuk dalam famili Pectinidae. Deskripsi umum simping menurut Sabelli (1979) adalah mempunyai bentuk pipih, sedikit cembung pada bagian tengah cangkang, terdiri atas dua cangkang yang sama besar. Ukuran panjang medium pada umumnya antara 3-4 inci. Tidak seperti famili Pectinidae lainnya, kedua kuping sama besar dan simetris pada kedua cangkangnya. Cangkang bagian atas berwarna pink kecoklatan dan bagian bawah berwarna putih. Permukaan luar cangkang halus dan licin.

“…During escapes, rapid contractions of the phasic adductor muscle expel water from the cavity between the valves. As escapes occur in response to the most dangerous predators (Legault and Himmelman 1993;Himmelman et al 2009), their contribution to overall fitness would seem considerable. Escape response performance is sensitive to the physiological status of scallops.…”

-We examined whether escape response performance and mitochondrial capacities could reveal differences created by feeding scallops, Argopecten purpuratus, mono-specific algal diets composed of either Chaetoceros calcitrans or Isochrysis galbana (variety T. iso) hereafter T. iso. Before and after feeding scallops with these diets, we assessed force production in vivo to evaluate escape response performance (initial and repeat). We measured oxidative capacities of mitochondria isolated from the adductor muscle and from the male and female portions of the gonad. Initial escape response performance was reduced more by the C. calcitrans diet than by the T. iso diet. Repeat escape responses, which require aerobic recuperation, were reduced by both treatments. The oxidative capacity of mitochondria isolated from muscle and female gonad was markedly lower in scallops fed C. calcitrans than in those fed T. iso. Flux through complex I-IV and through complex IV was also lower in mitochondria from muscle of scallops fed C. calcitrans than in those fed T. iso. Muscle aerobic capacity, assessed by citrate synthase activity, was lower in scallops fed C. calcitrans than in those fed T. iso. Despite the marked differences in fatty acid (FA) composition of the algal diets, the FA composition of mitochondrial phospholipids differed little between scallops fed C. calcitrans and those fed T. iso. Both escape response behaviour and mitochondrial capacities changed with feeding mono-specific diets. The simplicity of measurements of scallop escape responses suggests this as a practical means of evaluating the status of scallops for the two monoalgal diets tested.
