The Seasonal Toxicological Profile of Four Puffer Fish Species Collected Along Bengal Coast, India
Indian Journal of Marine Sciences Vol 33(3), September 2004, pp. 276-280 The seasonal toxicological profile of four puffer fish species collected along Bengal coast, India Somiranjan Ghosh, Alok K. Hazra, Shivaji Banerjee & Biswapati Mukherjee* S. N. Pradhan Centre for Neurosciences, University of Calcutta, 244B, Acharya J. C. Bose Road, Calcutta – 700 020, India *[E-mail : [email protected]] Received 17 November 2003, revised 29 June 2004 Toxicological profiles of the livers and ovaries of four Indian marine puffer fish species viz. Chelonodon patoca, Takifugu oblongus, Lagocephalus lunaris, Lagocephalus inermis collected along coastal Bengal of Digha-Talsari region were evaluated by mouse bioassay. Toxicity expressed in MU (mouse unit)/g in ovaries of all four species were high in monsoon (13.9 – 80 MU/g) and postmonsoon (8.9 – 136 MU/g) seasons during annual reproductive cycle. However, toxicity of livers was much lower (3.2 – 18.5 MU/g) in all the species with seasonal variation. Chelonodon patoca specimens were found to be most toxic and Lagocephalus inermis were least toxic in comparison to other species under investigation. Therefore, health hazard due to puffer fish consumption could be minimised by the information given in this study regarding lethality.

Piscat. 49 (2): 133–146. Background. Overexploitation of fishery resources has led to the capture of alternative species of a lower trophic level, considered previously unprofitable or unfit for human consumption. The southern pufferfish, Sphoeroides nephelus (Goode et Bean, 1882), is a bycatch species of the recreational fishery in the USA and Mexico. Unlike other species of the genus Sphoeroides, there is no background on their reproductive cycle. Therefore, this study aimed to describe several reproductive traits (sex ratio, gonadal development, annual reproductive cycle, and fecundity) of specimens from the northern coast of the Yucatan Peninsula, Mexico. This kind of information might serve as a point of reference for its potential use either in the pharmaceutical industry, aquarium trade, as well as in aquaculture. -

Constraints on the Timescale of Animal Evolutionary History
Palaeontologia Electronica palaeo-electronica.org Constraints on the timescale of animal evolutionary history Michael J. Benton, Philip C.J. Donoghue, Robert J. Asher, Matt Friedman, Thomas J. Near, and Jakob Vinther ABSTRACT Dating the tree of life is a core endeavor in evolutionary biology. Rates of evolution are fundamental to nearly every evolutionary model and process. Rates need dates. There is much debate on the most appropriate and reasonable ways in which to date the tree of life, and recent work has highlighted some confusions and complexities that can be avoided. Whether phylogenetic trees are dated after they have been estab- lished, or as part of the process of tree finding, practitioners need to know which cali- brations to use. We emphasize the importance of identifying crown (not stem) fossils, levels of confidence in their attribution to the crown, current chronostratigraphic preci- sion, the primacy of the host geological formation and asymmetric confidence intervals. Here we present calibrations for 88 key nodes across the phylogeny of animals, rang- ing from the root of Metazoa to the last common ancestor of Homo sapiens. Close attention to detail is constantly required: for example, the classic bird-mammal date (base of crown Amniota) has often been given as 310-315 Ma; the 2014 international time scale indicates a minimum age of 318 Ma.

Abstract A checklist of shallow (to 60 m depth) reef fishes is provided for the Bird’s Head Peninsula region of West Papua, Indonesia. The area, which occupies the extreme western end of New Guinea, contains the world’s most diverse assemblage of coral reef fishes. The current checklist, which includes both historical records and recent survey results, includes 1,511 species in 451 genera and 111 families. Respective species totals for the three main coral reef areas – Raja Ampat Islands, Fakfak-Kaimana coast, and Cenderawasih Bay – are 1320, 995, and 877. In addition to its extraordinary species diversity, the region exhibits a remarkable level of endemism considering its relatively small area. A total of 26 species in 14 families are currently considered to be confined to the region.

There was no previous report on piscine diversity of this river in Assam. Survey was conducted in the lower stretch of the river in Goalpara district from April 2018 to March 2019. Fish specimens were collected from five pre-selected sites, preserved and identified adopting standard methods. A total of 74 fish species belonging to nine (9) orders, 26 families and 58 genera were recorded. Cypriniformes was the dominant order with 35 species followed by Siluriformes with 19 species. IUCN status shows two vulnerable, eight near threatened and 66 species under the least concern category. Prevalence of anthropogenic threats like garbage dispersal and agricultural pesticide flow to the river, setting of brick industries on the bank, poison fishing in the upper stretch etc. may affect the fish population in this river. In this regard, awareness is the need of the hour among the inhabitants of the surrounding villages. Keywords: Ichthyofauna, Jinari River, Goalpara, Brahmaputra River, Assam INTRODUCTION The Northeastern region of India is considered to be one of the hotspots of freshwater fish biodiversity in the world (Ramanujam et al., 2010). -

National Prioritization of Key Vulnerable Reef Fish Species for Fiji, for Targeted Research
National prioritization of key vulnerable reef fish species for Fiji, for targeted research Coral reef fish and invertebrates sold at the Suva market. Photo by: Sangeeta Mangubhai/WCS Introduction The majority of Fiji’s population is coastal and therefore highly reliant on inshore fisheries for their subsistence and local economic needs (Hunt 1999). At least 33 percent of all animal protein consumed in Fiji comes from fish, and subsistence and artisanal fisheries contribute at least US$59.1 million to Fiji’s annual GDP (Gillett 2009). There is growing concerns for the impacts of present day harvesting rates and methods, especially for vulnerable fish and invertebrate species in Fiji. This is resulting in a progressive decline in fish belonging to higher trophic (feeding) groups, a pattern that is termed “fishing down food webs” (Pauly et al. 1998). Coral reef fish vary in their vulnerability to fishing pressure, and how well they can recover, if fishing is stopped or significantly reduced. Recovery potential relates to the rate at which a species can replace the individuals that are lost to natural mortality and to fishing. In general, the medium to larger carnivorous fish high in the food chain are thought to be more vulnerable to fishing (e.g. groupers) requiring in decades to recover, while smaller fish (e.g. herbivores such as rabbitfish) are thought be less vulnerable (Abesamis et al. 2014). Certain life history characteristics of fish species together can be good predictors of vulnerability at the population level to fishing pressure, including: (a) maximum size; (b) body growth rate; (c) lifespan; (d) natural mortality rates; (e) age at maturity; and (f) length at maturity (Abesamis et al. -
OSTRACIIDAE Boxfishes by K
click for previous page 3948 Bony Fishes OSTRACIIDAE Boxfishes by K. Matsuura iagnostic characters: Small to medium-sized (to 40 cm) fishes; body almost completely encased Din a bony shell or carapace formed of enlarged, thickened scale plates, usually hexagonal in shape and firmly sutured to one another; no isolated bony plates on caudal peduncle. Carapace triangular, rectangular, or pentangular in cross-section, with openings for mouth, eyes, gill slits, pectoral, dorsal, and anal fins, and for the flexible caudal peduncle. Scale-plates often with surface granulations which are prolonged in some species into prominent carapace spines over eye or along ventrolateral or dorsal angles of body. Mouth small, terminal, with fleshy lips; teeth moderate, conical, usually less than 15 in each jaw. Gill opening a moderately short, vertical to oblique slit in front of pectoral-fin base. Spinous dorsal fin absent; most dorsal-, anal-, and pectoral-fin rays branched; caudal fin with 8 branched rays; pelvic fins absent. Lateral line inconspicuous. Colour: variable, with general ground colours of either brown, grey, or yellow, usually with darker or lighter spots, blotches, lines, and reticulations. carapace no bony plates on caudal peduncle 8 branched caudal-fin rays Habitat, biology, and fisheries: Slow-swimming, benthic-dwelling fishes occurring on rocky and coral reefs and over sand, weed, or sponge-covered bottoms to depths of 100 m. Feed on benthic invertebrates. Taken either by trawl, other types of nets, or traps. Several species considered excellent eating in southern Japan, although some species are reported to have toxic flesh and are also able to secrete a substance when distressed that is highly toxic, both to other fishes and themselves in enclosed areas such as holding tanks. -
