Retail Stores Policies for Marketing of Lobsters in Sardinia (Italy) As Influenced by Different Practices Related to Animal Welf
foods Article Retail Stores Policies for Marketing of Lobsters in Sardinia (Italy) as Influenced by Different Practices Related to Animal Welfare and Product Quality Giuseppe Esposito 1, Daniele Nucera 2 and Domenico Meloni 1,* ID 1 Department of Veterinary Medicine, University of Sassari, Via Vienna 2, 07100 Sassari, Italy; [email protected] 2 Department of Agriculture, Forest and Food Science, University of Turin, Via Verdi 8, 10124 Turin, Italy; [email protected] * Correspondence: [email protected]; Tel.: +39-079-229-570; Fax: +39-079-229-458 Received: 12 June 2018; Accepted: 29 June 2018; Published: 2 July 2018 Abstract: The aim of the present study was to evaluate the marketing policies of lobsters as influenced by different practices related to product quality in seven supermarkets located in Italy. Retailers were divided in two categories: large scale and medium scale. The two groups were compared to screen for differences and to assess differences in score distribution attributed to different practices related to product quality. Our results showed no statistical differences (p > 0.05) between the two categories. Lobsters were often marketed alive on ice and/or stocked for long periods in supermarket aquariums, highlighting the need to improve the specific European regulations on health, welfare, and quality at the market stage. Retail shop managers should be encouraged to develop better practices and policies in terms of marketing of lobsters. This will help in keeping the animals in good health and improve product quality at the marketing stages. Keywords: crustaceans; supermarkets; aquarium; ice 1. Introduction In the last decades, the global total consumption of seafood products has increased: this has resulted in a rapidly growing demand for these products, especially in emerging markets [1]. -

Several hundred adult specimens of crabs and lobster from two tunicate- infested estuaries and Northumberland Strait were examined for epibionts. Small patches of Botrylloides violaceus were found on rock crabs examined from Savage Harbour and a small colony of Botryllus schlosseri was found on one lobster from St. Peters Bay. Lobster and lady crab collected in Northumberland Strait had no attached colonial tunicates but small sea grapes (Molgula sp.) were found attached on the underside of 5.5% of the rock crab and on 2.5% of lobster collected in Northumberland Strait in August 2006. -
Challenging the Cold: Crabs Reconquer the Antarctic

Recent records of lithodid crabs in deeper waters off the Antarctic continental slope raised the question of the return of crabs to Antarctic waters, following their extinction in the lower Miocene ;15 million years ago. Antarctic cooling may be responsible for the impoverishment of the marine high Antarctic decapod fauna, presently comprising only ®ve benthic shrimp species. Effects of polar conditions on marine life, including lowered metabolic rates and short seasonal food availability, are discussed as main evolutionary driving forces shaping Antarctic diversity. In particular, planktotrophic larval stages should be vulnerable to the mismatch of prolonged development and short periods of food avail- ability, selecting against complex life cycles. We hypothesize that larval lecithotrophy and cold tolerance, as recently observed in Subantarctic lithodids, represent, together with other adaptations in the adults, key features among the life-history adaptations of lithodids, potentially enabling them to conquer polar ecosystems. The return of benthic top predators to high Antarctic waters under conditions of climate change would considerably alter the benthic communities. -
Introduction Porcupine Crab (Neolithodes Grimaldii)
Introduction as the king crab family of which 79 species have been identified throughout the oceans of the world. Male Porcupine Crab (Neolithodes grimaldii) specimens have been measured with a carapace length inhabits the sea bed off the Coast of Newfoundland (CL) of 180 mm and weighing 2.28 kg. Females of the and Labrador in depths beyond 500 fathoms (fm). species do not grow quite as large but carapace lengths This large crab is often caught as a by-catch in the up to 160 mm have been recorded. turbot gillnet fishery. Preliminary experiments with processing limited amounts have shown that marketable crab meat products can be produced from porcupine crab. Attempts have been made to increase the volume of raw material for processing by utilizing the by-catch, either by sectioning the crab onboard the vessel or landing whole crab, iced in boxes. This approach has not proven effective mainly because the crab has to be removed from gillnets which is extremely time consuming, especially when large quantities are involved. Also, fishermen try to avoid porcupine crab as turbot is their main species. It is generally accepted that if the fishery is to develop a method of potting the crab has to be devised. To date this has not been accomplished in spite of two The crab has three pairs of walking legs and separate projects in which various pot designs and bait one pair of claws. The right claw is larger than the left types were set in locations where porcupine crab had and is probably used for crushing while the smaller left been caught in turbot nets. -

Rec. zool. Surv. India, 106 (Part-I) : 39-42, 2006 A NOTE ON THE FIRST REPORT OF MACROBRACHIUM JOSEPHI JAY ACHANDRAN, 2001 OUT OF THE TYPE LOCALITY K. V ALARMATHI AND M. B. RAGHUNATHAN Southern Regional Station, Zoological Survey of India, Chennai-28 INTRODUCTION While examining the freshwater prawns deposited in the Southern Regional Station of the Zoological Survey of India, the authors have came across Macrobrachium josephi Jayachandrana, 2001 (Plate-l), which is known to occur only in Kerala. From earlier reports it is known that nearly 10 species of the freshwater prawns of the genus Macrobrachium are available in Tamil Nadu (Raghunath an and Valarmathi, 2005). The species reported are Macrobrachium aemulum (Nobili), Macrobrachium australe (Guerin-Meneville, 1838), Macrobrachium canarae (Tiwari, 1958), Macrobrachium lamarrei lamarrei (H. Milne Edward, 1952), Macrobrachium malcolmsonii (Milne Edward, 1837), Macrobrachium nobilii (Henderson and Matthai, 1910), Macrobrachium rosenbergii (de Man, 1879), Macrobrachium rude (Heller, 1862), Macrobrachium scabriculum (Heller, 1862), Macrobrachium indicum Jaychandran et Joseph, 1986. The present study yields one more species of Macrobrachium to Tamil Nadu. MATERIAL EXAMINED 3G and 3E from a rock pool, Medavakkam, Chennai, Tamil Nadu, 09-VII-2004, ColI. : K. Valarmathi. DIAGNOSTIC CHARACTERS Rostrum with slight basal crest raised above the orbit and is longer than the antennular peduncle but falls short of the antennal scale. The upper margin of the rostrum is provided with 10 to 13 teeth of which 2 or 3 are located on the carapace, and the lower margin of the rostrum posses 5-6 teeth. The structure and the arrangement of spines on the rostrum are similar to Macrbrachium malcolmsonii. -

Received: 6 March 2019; Accepted: 4 April 2019; Published: 8 April 2019 Abstract: Luteinizing hormone (LH), a pituitary gonadotropin, coupled with LH receptor (LHR) is essential for the regulation of the gonadal maturation in vertebrates. Although LH homolog has been detected by immunocytochemical analysis, and its possible role in ovarian maturation was revealed in decapod crustacean, so far there is no molecular evidence for the existence of LHR. In this study, we cloned a novel LHR homolog (named EsLHR) from the Chinese mitten crab Eriocheir sinensis. The complete sequence of the EsLHR cDNA was 2775bp, encoding a protein of 924 amino acids, sharing 71% amino acids identity with the ant Zootermopsis nevadensis LHR. -
