E-mail: [email protected] Received: 07 December 2016/Accepted: 20 December 2016/ Published: 29 December 2016 Abstract: Marine organisms are a rich source of natural products with potential secondary metabolites that have great pharmacological activity. Starfish are known as by-catch products in the worldwide fishing industry and most of starfish have been got rid of by fire destruction without any utilization. On the other hand, starfish are considered as extremely rich sources of biological active compounds in terms of having pharmacological activity. In the present study, molecular identification of starfish species, micronutrient content and hemolytic activity from Luidia quinaria, Astropecten scoparius, and Patiria pectinifera were examined. Nucleotide sequence analysis of the 16S rRNA gene fragment of mitochondrial DNA indicated that partial sequences of PCR products of the species was identical with that of L. quinaria, A. scoparius, and P. pectinifera. From the results of micronutrient contents, there were no great differences on the micronutrient among species. -

Predator and Scavenger Aggregation to Discarded By-Catch from Dredge Fisheries: Importance of Damage Level
Journal of Sea Research 51 (2004) 69–76 www.elsevier.com/locate/seares Short Communication Predator and scavenger aggregation to discarded by-catch from dredge fisheries: importance of damage level S.R. Jenkinsa,b,*, C. Mullena, A.R. Branda a Port Erin Marine Laboratory (University of Liverpool), Port Erin, Isle of Man, British Isles, IM9 6JA, UK b Marine Biological Association, Citadel Hill, Plymouth, PL1 2PB, UK Received 23 October 2002; accepted 22 May 2003 Abstract Predator and scavenger aggregation to simulated discards from a scallop dredge fishery was investigated in the north Irish Sea using an in situ underwater video to determine differences in the response to varying levels of discard damage. The rate and magnitude of scavenger and predator aggregation was assessed using three different types of bait, undamaged, lightly damaged and highly damaged individuals of the great scallop Pecten maximus. In each treatment scallops were agitated for 40 minutes in seawater to simulate the dredging process, then subjected to the appropriate damage level before being tethered loosely in front of the video camera. The density of predators and scavengers at undamaged scallops was low and equivalent to recorded periods with no bait. Aggregation of a range of predators and scavengers occurred at damaged bait. During the 24 hour period following baiting there was a trend of increasing magnitude of predator abundance with increasing damage level. However, badly damaged scallops were eaten quickly and lightly damaged scallops attracted a higher overall magnitude of predator abundance over a longer 4 day period. Large scale temporal variability in predator aggregation to simulated discarded biota was examined by comparison of results with those of a previous study, at the same site, 4 years previously. -

Around 1,500 living species of starfish occur on the seabed in all the world's oceans, from the tropics to subzero polar waters. They are found from the intertidal zone down to abyssal depths, 6,000m below the surface. Starfish typically have a central disc and five arms, though some species have a larger number of arms. The aboral or upper surface may be smooth, granular or spiny, and is covered with overlapping plates. -
Guanidinium Toxins and Their Interactions with Voltage-Gated Sodium Ion Channels

Cembella 2 ID 1 CONACYT—Instituto de Ciencias del Mary Limnología, Universidad Nacional Autónoma de México, Mexico 04510, Mexico 2 Alfred-Wegener-Institut, Helmholtz Zentrum für Polar-und Meeresforschung, 27570 Bremerhaven, Germany; [email protected] * Correspondence: [email protected]; Tel.: +52-55-5623-0222 (ext. 44639) Received: 29 June 2017; Accepted: 27 September 2017; Published: 13 October 2017 Abstract: Guanidinium toxins, such as saxitoxin (STX), tetrodotoxin (TTX) and their analogs, are naturally occurring alkaloids with divergent evolutionary origins and biogeographical distribution, but which share the common chemical feature of guanidinium moieties. These guanidinium groups confer high biological activity with high affinity and ion flux blockage capacity for voltage-gated sodium channels (NaV). Members of the STX group, known collectively as paralytic shellfish toxins (PSTs), are produced among three genera of marine dinoflagellates and about a dozen genera of primarily freshwater or brackish water cyanobacteria. In contrast, toxins of the TTX group occur mainly in macrozoa, particularly among puffer fish, several species of marine invertebrates and a few terrestrial amphibians. In the case of TTX and analogs, most evidence suggests that symbiotic bacteria are the origin of the toxins, although endogenous biosynthesis independent from bacteria has not been excluded. The evolutionary origin of the biosynthetic genes for STX and analogs in dinoflagellates and cyanobacteria remains elusive. These highly potent molecules have been the subject of intensive research since the latter half of the past century; first to study the mode of action of their toxigenicity, and later as tools to characterize the role and structure of NaV channels, and finally as therapeutics. -

[email protected]; [email protected] 2 Museo de Ciencias Naturales Bernardino Rivadavia, Ángel Gallardo 470, Ciudad Autónoma de Buenos Aires, Argentina. [email protected]; [email protected] ABSTRACT. Asterozoans are free living, star-shaped echinoderms which are important components of benthic marine faunas worldwide. Their fossil record is, however, poor and fragmentary, probably due to dissarticulation of ossicles. In particular, fossil asteroids are infrequent in South America. A new species of starfish is reported from the early Valanginian of the Mulichinco Formation, Neuquén Basin, in the context of a shallow-water, storm-dominated shoreface environment. The specimen belongs to the Astropectinidae, and was assigned to a new species within the genus Tethyaster Sladen, T. antares sp. nov., characterized by a R:r ratio of 2.43:1, rectangular marginals wider in the interbrachial angles, infero- marginals (28 pairs along a median arc) with slightly convex profile and flat spines (one per ossicle in the interbrachials and two per ossicle in the arms). -

ABSTRACT: Whole-body extracts in methanol were obtained from the starfish Stellaster equestris. The crude toxin was fractionated stepwise using diethylaminoethyl (DEAE) cellulose column chromatography. The crude toxin was lethal to male albino mice at a dose of 1.00 mL (containing 531.0 µg/mL protein) when injected intraperitoneally (IP) but the toxicity was abolished in all cases except one upon fractionation. The crude toxin and all the adsorbed fractions exhibited potent hemolytic activity on chicken, goat and human blood. However, group B human erythrocytes were resistant to lysis by all fractions and group O by most of the fractions. Paw edema in mice was caused by the crude toxin and all fractions. Pheniramine maleate and piroxicam blocked the toxicity when administered earlier than, or along with, the crude or fractionated toxins but not when administered after the envenomation. Pretreatment with either of these drugs also blocked edema formation. KEY WORDS: starfish, toxicity, hemolysis, human blood groups, paw edema. CONFLICTS OF INTEREST: There is no conflict.

Firstly, I would like to thank my supervisor, Professor Paul B. Rainey (New Zealand Institute of Advanced Study, Massey University), for providing me with the opportunity to join his research group. He gave me constant support, insightful guidance, valuable input, and showed me how to think like a scientist. I would also like to thank my co- supervisor, Dr Craig D. Millar, who welcomed me into his genetics laboratory at the Department of Biological Sciences at the University of Auckland whenever I needed help. He guided me patiently right from the beginning of my PhD project, was generous with his time, encouraging, and taught me how to troubleshoot where necessary. I would like to extend a special mention to Selina Patel, a very talented technician at Dr Millar’s Lab who shared her extensive technical and theoretical knowledge with me generously, but also allocated considerable time to help me progress with my research. -
