Kizhakudan Research Centre of CMFRI, Chennai 3f With the decline in many commercial fisheries worldwide and an ever­ increasing demand for seafood protein, there is a growing need for augmenting the production of high-protein, high-value resources like lobsters. Aquaculture remains the ideal measure to augment production and ensure conseNation, and even enhancement. of natural stocks. Aquaculture provides a two-pronged solution towards increasing the fish production through ., farming of hatchery-produced seed of commercially important finfishes and shellfishes , enhancing natural stocks by sea ranching hatchery-produced seed of commercially important finfishes and shellfishes Lobsters are among the most priced seafood delicacies enjoying a special demand in international markets. As against a world average annual productio'n of2.1 lakh tonnes, India's average annual lobster production is about 2000 tonnes. With the distinction of being perhaps, the only seafood resource in India's trade economy, which remains relatively low down the ladder in terms of quantity of production but brings in maximum foreign exchange, lobsters have been the subject of study for more than two decades now.

  • Isles of Scilly Lobster (Homarus Gammarus) and Crawfish (Palinurus Elephas) Tagging Project
    Isles of Scilly lobster (Homarus gammarus) and crawfish (Palinurus elephas) tagging project. Douglas Holt and Daisy Kelly-Fletcher IOSIFCA1601 Executive Summary The Isles of Scilly Inshore fisheries and Conservation Authority began a shellfish monitoring project within the Isles of Scilly district in 2013. This project aimed to study the distribution, reproduction, movement and growth patterns of two large decapod species; the European Common Lobster H.gammarus and the European Crawfish Palinurus elephas, both of which are economically important marine resources to the islands fishing industry. The project, now in its third year, has gathered data on almost 8,000 animals. In 2014 the value of the lobster fishery of the Isles of Scilly was approximately £140,000 and the crawfish fishery was £45,000 (MMO Landing records). Although more valuable per unit at market the crawfish is far less abundant than the lobster within the Isles of Scilly district. Both species are managed by national legislation but there is considerably more protection offered to the European Lobster at a local scale. The Isles of Scilly has one of the few remaining fisheries for the crawfish, which has been declining in abundance since the 1970s. In light of this, the Spiny Lobster was designated in 2013 as a feature of the islands’ MCZ and has been given a ‘recover to favourable condition’ conservation objective as part of scheme. The results of this project show a sustainable level of exploitation for the local lobster populations. Both male and female lobsters were sampled in equal proportions and of those sampled approximately half were returned the fishery.

  • The Utilization of Lobsters by Humans in the Mediterranean Basin from the Prehistoric Era to the Modern Era – an Interdisciplinary Short Review
    Athens Journal of Mediterranean Studies- Volume 1, Issue 3 – Pages 223-234 The Utilization of Lobsters by Humans in the Mediterranean Basin from the Prehistoric Era to the Modern Era – An Interdisciplinary Short Review By Ehud Spanier The Mediterranean and Red Seas host a variety of clawed, spiny and slipper lobsters. Lobsters' utilization in ancient times varied, ranging from complete prohibition by the Jewish religion, to that of epicurean status in the Roman world. One of the earliest known illustrations of a spiny lobster was a wall carving in Egypt depicting the Queen Hatshepsut expedition to the Red Sea in the 15th century BC. Lobsters were known by the ancient Greeks and Romans as was expressed in art forms and writings. Lobsters also appeared in ancient mosaics and coins. The writings of naturalists and philosophers from the Roman-Hellenistic period, together with illustrative records indicate that lobsters were a popular food and there was considerable knowledge of their classification, biology and fisheries. The popularity of lobsters as gourmet food increased with time followed by an expansion of the scientific knowledge as well as over exploitation of these resources. Keywords: Antiquity, Biology, Fisheries, Lobsters, Mediterranean. Introduction A variety of edible lobsters, that are still commercially significant to human inhabitants today, are found in the water of the Mediterranean and adjacent Red Sea regions. This important marine resource includes at least two Mediterranean clawed lobsters (the European lobster, Homarus gammarus, and the Norway lobster, Nephrops norvegicus), five spiny lobsters (two in the Mediterranean: the common spiny lobster, Palinurus elephas, and the pink spiny lobster, P.

The study of the Portuguese marine ichthyofauna has a long historical tradition, rooted back in the 18th Century. Here we present an annotated checklist of the marine fishes from Portuguese waters, including the area encompassed by the proposed extension of the Portuguese continental shelf and the Economic Exclusive Zone (EEZ). The list is based on historical literature records and taxon occurrence data obtained from natural history collections, together with new revisions and occurrences.

  • Quantitative Species-Level Ecology of Reef Fish Larvae Via Metabarcoding
    ARTICLES https://doi.org/10.1038/s41559-017-0413-2 Quantitative species-level ecology of reef fish larvae via metabarcoding Naama Kimmerling1,2, Omer Zuqert3, Gil Amitai3, Tamara Gurevich2, Rachel Armoza-Zvuloni2,8, Irina Kolesnikov2, Igal Berenshtein1,2, Sarah Melamed3, Shlomit Gilad4, Sima Benjamin4, Asaph Rivlin2, Moti Ohavia2, Claire B. Paris 5, Roi Holzman 2,6*, Moshe Kiflawi 2,7* and Rotem Sorek 3* The larval pool of coral reef fish has a crucial role in the dynamics of adult fish populations. However, large-scale species-level monitoring of species-rich larval pools has been technically impractical. Here, we use high-throughput metabarcoding to study larval ecology in the Gulf of Aqaba, a region that is inhabited by >500 reef fish species. We analysed 9,933 larvae from 383 samples that were stratified over sites, depth and time. Metagenomic DNA extracted from pooled larvae was matched to a mitochondrial cytochrome c oxidase subunit I barcode database compiled for 77% of known fish species within this region. This yielded species-level reconstruction of the larval community, allowing robust estimation of larval spatio-temporal distribu- tions. We found significant correlations between species abundance in the larval pool and in local adult assemblages, suggest- ing a major role for larval supply in determining local adult densities. We documented larval flux of species whose adults were never documented in the region, suggesting environmental filtering as the reason for the absence of these species. Larvae of several deep-sea fishes were found in shallow waters, supporting their dispersal over shallow bathymetries, potentially allow- ing Lessepsian migration into the Mediterranean Sea.

Impacts of estuary weirs on fish assemblages are particularly distinct because the weirs are disturbed in linking between freshwater and estuarine fish communities, and migration successes for regional fish fauna. This study conducted fish sampling at the lower reaches of the Nakdong River to assess spatio-temporal variations in fish assemblages, and effects of estuary weir on structuring fish assemblage between freshwater and estuary habitats. In total, 20,386 specimens comprising 78 species and 41 families were collected. The numerical dominant fish species were Tachysurus nitidus (48.8% in total abundance), Hemibarbus labeo (10.7%) and Chanodichthys erythropterus (3.6%) in the freshwater region, and Engraulis japonicus (10.0%), Nuchequula nuchalis (7.7%) and Clupea pallasii (5.2%) in the estuarine site.

  • Review of the Biology, Ecology and Fisheries of Palinurus Spp. Species
    Cah. Biol. Mar. (2005) 46 : 127-142 Review of the biology, ecology and fisheries of Palinurus spp. species of European waters: Palinurus elephas (Fabricius, 1787) and Palinurus mauritanicus (Gruvel, 1911) Raquel GOÑI1 and Daniel LATROUITE2 (1) Centro Oceanográfico de Baleares – Instituto Español de Oceanografía.

E-mail: [email protected] Abstract: Palinurus elephas and Palinurus mauritanicus are the only species of the family Palinuridae that occur in the Northeast Atlantic and Mediterranean. Of the two, Palinurus elephas is the most abundant and accessible and has traditionally been the preferred target of lobster fisheries throughout its range. Palinurus mauritanicus has a deeper distri- bution and has been an important target of fisheries mainly in the Central Eastern Atlantic. The high unit value and the rel- ative scarcity of these species have been important obstacles to research and knowledge of their biology, ecology and fish- eries is limited. Nevertheless, over time a considerable number of studies has been conducted, though most of these are contained in university theses or in publications of limited circulation. This review is an up-to-date overview of available knowledge on the biology, ecology and fisheries of the two spiny lobster species of European waters. Résumé : Une revue sur la biologie, l’écologie et les pêcheries des espèces de Palinurus des eaux européennes : Palinurus elephas (Fabricius, 1787) et Palinurus mauritanicus (Gruvel, 1911).
