  • Cartilaginous Fish: Sharks, Sawfish and Stingrays
    Cartilaginous fish: Sharks, sawfish and stingrays. It may come as a surprise to some readers that there are sharks, sawfish and stingrays in the Mekong River, because most people connect these fishes with the big oceans. Most species in these groups are in fact strictly marine. However, several species have some tolerance to freshwater and have the ability to venture far up into rivers during their searches for food, while a few live their entire life in fresh water. Sharks, sawfish and stingrays are all cartilaginous fishes (the class Chondrichthyes), while all the species we have presented in Catch and Cultures supplement series until this point have been bony fish (the class Osteichthyes). Let us therefore start by looking at the characters that distinguish cartilaginous fish from bony fishes. As implied in the name, the skeleton in cartilaginous fish does not include bone but consists of cartilage, and all Fins supported by the fins are supported by horny horny structures structures rather than fin rays. Gill openings seen as Body covered with None of the species possess a a series of slits denticles swimbladder, the organ most bony fish use to prevent them from sinking to the bottom.

  • Fish Biodiversity of Indian Exclusive Economic Zone K
    ICAR-Central Marine Fisheries Research Institute Fish Biodiversity of Indian Exclusive Economic Zone K. K. Joshi ICAR-Central Marine Fisheries Research Institute [email protected] Introduction Indian fisheries have a long history, starting with Kautilya’s Arthasastra describing fish as a source for consumption and provide evidence that fishery was a well-established industry in India and fish was relished as an article of diet as early as 300 B.C, the ancient Hindus possessed a considerable knowledge on the habit of fishes and the epic on the second pillar of Emperor Ashoka describing the prohibition of consumption of fish during a certain lunar period which can be interpreted as a conservation point of view. Modern scientific studies on Indian fishes could be traced to the initial works done by Linnaeus, Bloch and Schneider, Lacepède, Russell and Hamilton. The mid 1800s contributed much in the history of Indian fish taxonomy since the time of the expeditions was going through. Cuvier and Valenciennes (1828-1849) described 70 nominal species off Puducherry, Skyes (1839), Günther (1860, 1872, 1880) and The Fishes of India by Francis Day (1865-1877) and another book Fauna of British India series in two volumes (1889) describing 1,418 species are the two most indispensable works on Indian fish taxonomy to date. Alcock (1889, 1890) described 162 species new to science from Indian waters. In the 20th century, the basis of intensive studies on the different families and groups of freshwater fishes was done by Chaudhuri along with Hora and his co-workers. Misra published An Aid to Identification of the Commercial Fishes of India and Pakistan and The Fauna of India and Adjacent Countries (Pisces) in 1976.

  • Species Composition of the Largest Shark Fin Retail-Market in Mainland
    www.nature.com/scientificreports OPEN Species composition of the largest shark fn retail‑market in mainland China Diego Cardeñosa1,2*, Andrew T. Fields1, Elizabeth A. Babcock3, Stanley K. H. Shea4, Kevin A. Feldheim5 & Demian D. Chapman6 Species‑specifc monitoring through large shark fn market surveys has been a valuable data source to estimate global catches and international shark fn trade dynamics. Hong Kong and Guangzhou, mainland China, are the largest shark fn markets and consumption centers in the world. We used molecular identifcation protocols on randomly collected processed fn trimmings (n = 2000) and non‑ parametric species estimators to investigate the species composition of the Guangzhou retail market and compare the species diversity between the Guangzhou and Hong Kong shark fn retail markets. Species diversity was similar between both trade hubs with a small subset of species dominating the composition. The blue shark (Prionace glauca) was the most common species overall followed by the CITES‑listed silky shark (Carcharhinus falciformis), scalloped hammerhead shark (Sphyrna lewini), smooth hammerhead shark (S. zygaena) and shortfn mako shark (Isurus oxyrinchus). Our results support previous indications of high connectivity between the shark fn markets of Hong Kong and mainland China and suggest that systematic studies of other fn trade hubs within Mainland China and stronger law‑enforcement protocols and capacity building are needed. Many shark populations have declined in the last four decades, mainly due to overexploitation to supply the demand for their fns in Asia and meat in many other countries 1–4. Mainland China was historically the world’s second largest importer of shark fns and foremost consumer of shark fn soup, yet very little is known about the species composition of shark fns in this trade hub2.

  • Report of 5Th General Assembly
    th 5 General Assembly of World Forum of Fisher Peoples (WFFP) World Forum of Fisher Peoples (WFFP): World Forum of Fisher Peoples (WFFP) is an international alliance of 36 mass based national organizations of fisherfolk working in 32 countries of all continents of the world. WFFP aims to protect, defend and strengthen the communities that depend on the fishery for their livelihood, and represents the small scale, artisanal fishers’ interest at the international level and play the role of global political organ of the same communities. Background of General Assembly: General Assembly of WFFP is organized after every three years as per the WFFP Constitution. So far WFFP’s three Constituent Assembly Meetings and one General Body had been held at Delhi, India; Loctudy, France; Kismu, Kenya and Negombo, Sri Lanka respectively. It ensures democratic functioning, elections for the new office bearers, plans out for the global common agenda for the artisanal; small scale fisher communities and the membership of 40 million fishers across the world. Fifth General Assembly of the World Forum of Fisher People was organized by PFF in Karachi from 27th to 30th April 2011 at Hotel Regent Plaza Karachi. Some 60 international delegates from 17 countries participated in this event. Major objectives of the meeting were as under: . To protect, defend and strengthen the communities that depend on fishing as their sole livelihood . To assist member organizations to secure and improve upon the economic viability and quality of life of Fisher People . To recognize, support and enhance the role of women in the social, economic, political and cultural life of the fishing community .

  • In the Tuna Gillnet Fisheries of Pakistan
    ____________________________________________IOTC-2021-WPEB17(DP)-14 Some Observation on the Silky Shark (Carcharhinus falciformis) in the Tuna Gillnet Fisheries of Pakistan Muhammad Moazzam WWF-Pakistan, Karachi, Pakistan ([email protected]) Abstract Sharks form important part of bycatch of the tuna gillnet operations in Pakistan. Silky shark (Carcharhinus falciformis) was observed to the most dominating species in commercial landings of oceanic sharks at Karachi Fish Harbour Pakistan followed by mako shark. This species is considered as commercially important, as it meat is locally consumed whereas fins are exported despite restrictions because this species is included in Appendix-II of CITES. During the present study it was observed that large sized specimens (161 cm to 191cm TL) were not caught during 2017 and 2018 whereas in 2016, silky shark of these size classes were caught by tuna gillnetters as bycatch indicating overfishing of shark in general and silky shark in particular. Introduction Sharks are considered as an important bycatch group of tuna gillnet fishing in Pakistan (Khan, 2013; Moazzam, 2013, 2019; Shahid et al., 2015, 2016). In Pakistan, gillnets consisting of monofilament and multifilament are used for catching tuna and tuna like species. Monofilament net is mainly used for catching neritic tuna in coastal waters whereas multifilament nylon nets are used for catching longtail tuna (Thunnus tonggol), yellowfin tuna (Thunnus albacares) and skipjack tuna (Katsuwonus pelamis) in the offshore waters. There are about 700 tuna gillnetters based mainly in Karachi along Sindh Coast and Gwadar along Balochistan Coast. A number of shark species were observed to be entangled in the tuna gillnets which is dominated by silky shark (Khan et al., 2013, Moazzam, 2012; Shahid, 2012; Shahid et al., 2015, 2016).
