GROWTH of Litopenaeus Schmitti (BURKENROAD, 1936) and Farfantepenaeus Paulensis (PEREZ-FARFANTE, 1967) SHRIMP REARED in RECIRCULATION CULTURE SYSTEM
BRAZILIAN JOURNAL OF OCEANOGRAPHY, 62(4):323-330, 2014 GROWTH OF Litopenaeus schmitti (BURKENROAD, 1936) AND Farfantepenaeus paulensis (PEREZ-FARFANTE, 1967) SHRIMP REARED IN RECIRCULATION CULTURE SYSTEM Marcelo Barbosa Henriques*, Pedro Mestre Ferreira Alves, Oscar José Sallée Barreto and Marcelo Ricardo de Souza Instituto de Pesca - Secretaria de Agricultura e Abastecimento do Estado de São Paulo (Av. Bartolomeu de Gusmão, 192, 11030-906 Santos, SP, Brasil) *Corresponding author: [email protected] http://dx.doi.org/10.1590/S1679-87592014078806204 A B S T R A C T The Litopenaeus schmitti and Farfantepenaeus paulensis shrimp captured in estuaries are marketed as live bait for recreational fishing. As an alternative to shrimp extractive activities, the authors evaluated the rearing of these species in a recirculation culture system. For each species, the grow-out study was carried out in two 120-day production cycles, using 3,300 juveniles of an average length of 25 mm and weight of 0.9 grams in each, distributed in 12 tanks of 1,500 liters and 1.32 m2, at a population density of 208.3 shrimp per m2. The growth parameters were obtained using the von Bertalanffy model based on the length (mm) and age (weeks) data. The adjustments were made in the R environment of the non-linear least-square method. The von Bertalanffy growth model showed a proper fit, with determination coefficients of 0.900 for L. schmitti and 0.841 for F. paulensis. The values of L∞ and k were 172.66 and 0.027 mm for L. schmitti and 110.13 mm and 0.050 for F. -
Pacific Marine Fisheries Commission
32nd Annual Report of the PACIFIC MARINE FISHERIES COMMISSION FOR THE YEAR 1979 TO THE CONGRESS OF THE UNITED STATES AND TO THE GOVERNORS AND LEGISLATURES OF WASHINGTON, OREGON, CALIFORNIA, IDAHO, AND ALASKA Pacific Marine Fisheries Commission 528 S.W. Mill Street Portland, Oregon 97201 July 8, 1980 32nd Annual Report of the PACIFIC MARINE FISHERIES COMMISSION FOR THE YEAR 1979 PREFACE The Pacific Marine Fisheries Commission was created in 1947 with the consent of Congress. The Commission serves five member States: Alaska, California, Idaho, Oregon and Washington. The purpose of this Compact, as stated in its Goal and Objectives, is to promote the wise management, utilization, and development of fisheries of mutual concern, and to develop a joint program of protection, enhancement, and prevention of physical waste of such fisheries. The advent of the Fishery Conservation and Management Act {FCMA) of 1976 and amendments thereto has caused spectacular and continuing changes in the management of marine fisheries in the United States. The FCMA created the Fishery Conservation Zone (FCZ) between 3 and 200 nautical miles offshore, established 8 Regional Fishery Management Councils with authority to develop fishery management plans within the FCZ, and granted the Secretary of Commerce the power to regulate both domestic and foreign fishing fleets within the FCZ. The FCMA greatly modified fishery management roles at state, interstate, national and international levels. The Pacific Marine Fisheries Commission recognized early that its operational role would change as a result of possible functional overlaps with the two regional fishery management councils established on the Pacific Coast. On the one hand, the FCMA provides non-voting Council membership to the Executive Directors of the interstate Marine Fisheries Commissions, thus assuring active participation as the Councils deliberate on fishery matters of concern to the States. -

Doremus_Final_Web_Ready_FINAL_12May2013 7/18/2013 4:24 PM WHY INTERNATIONAL CATCH SHARES WON’T SAVE OCEAN BIODIVERSITY Holly Doremus* Skepticism about the efficacy and efficiency of regulatory approaches has produced a wave of enthusiasm for market-based strategies for dealing with environmental conflicts. In the fisheries context, the most prominent of these strategies is the use of “catch shares,” which assign specific proportions of the total allowable catch to individuals who are then free to trade them with others. Catch shares are now in wide use domestically within many nations, and there are increasing calls for implementation of internationally tradable catch shares. Based on a review of theory, empirical evidence, and two contexts in which catch shares have been proposed, this Article explains why international catch shares are not likely to arrest the decline of ocean biodiversity. -

Fronts in the World Ocean's Large Marine Ecosystems. ICES CM 2007
- 1 - This paper can be freely cited without prior reference to the authors International Council ICES CM 2007/D:21 for the Exploration Theme Session D: Comparative Marine Ecosystem of the Sea (ICES) Structure and Function: Descriptors and Characteristics Fronts in the World Ocean’s Large Marine Ecosystems Igor M. Belkin and Peter C. Cornillon Abstract. Oceanic fronts shape marine ecosystems; therefore front mapping and characterization is one of the most important aspects of physical oceanography. Here we report on the first effort to map and describe all major fronts in the World Ocean’s Large Marine Ecosystems (LMEs). Apart from a geographical review, these fronts are classified according to their origin and physical mechanisms that maintain them. This first-ever zero-order pattern of the LME fronts is based on a unique global frontal data base assembled at the University of Rhode Island. Thermal fronts were automatically derived from 12 years (1985-1996) of twice-daily satellite 9-km resolution global AVHRR SST fields with the Cayula-Cornillon front detection algorithm. These frontal maps serve as guidance in using hydrographic data to explore subsurface thermohaline fronts, whose surface thermal signatures have been mapped from space. Our most recent study of chlorophyll fronts in the Northwest Atlantic from high-resolution 1-km data (Belkin and O’Reilly, 2007) revealed a close spatial association between chlorophyll fronts and SST fronts, suggesting causative links between these two types of fronts. Keywords: Fronts; Large Marine Ecosystems; World Ocean; sea surface temperature. Igor M.

Seafood Traceability for Fisheries Compliance – Country- Level Support for Catch Documentation Schemes
ISSN 2070-7010 FAO 619 FISHERIES AND AQUACULTURE TECHNICAL PAPER 619 Seafood traceability for fisheries compliance Country-level support for catch documentation schemes Seafood traceability for fisheries compliance This document explores ways in which individual countries in seafood supply chains can, in their capacities as coastal, flag, port, processing or end-market states, contribute to maximizing the effectiveness of catch documentation schemes. The focus is on the traceability of seafood consignments, but the authors also explore other important compliance mechanisms that are not directly related to traceability but – that support the effective implementation of catch documentation schemes at the Country-level support for catch documentation schemes country level. The document explains which traceability mechanisms are built into catch documentation schemes, and which additional support mechanisms must be provided by individual countries along seafood supply chains. The study finds that traditional fisheries monitoring, inspection and sanctioning mechanisms are of primary importance with regard to flag, coastal and end-market states, whereas effective country-level traceability mechanisms are critical of particular importance in port and processing states.

As Supplement in the Diets of Rabbits Reared Under Deep Litter System
Anti-Endo Parasitic Effects of Garlic (Allium sativum) as Supplement in the Diets of Rabbits Reared under Deep Litter System Bello, K.O.1*; Akanji, A.O.2; Irekhore, O.T.3 and Lala, A.O.1 1Institute of Food Security, Environmental Resources and Agricultural Research, Federal University of Agriculture, Abeokuta, Nigeria. 2Department of Animal Production and Health, Federal University of Agriculture, Abeokuta, Nigeria. 3Agricultural Medial Resources and Extension Centre, Federal University of Agriculture, Abeokuta, Nigeria. *Corresponding author: Email: [email protected] ABSTRACT This study was carried out to determine anti-endo parasitic effects of garlic (Allium sativum) in the diets of male (buck) and female (doe) weaner rabbits reared under deep litter system. Twenty-four cross bred weaner (8 weeks old) rabbits comprising twelve each of bucks and does were randomly allocated according to sex and feed supplement (conventional anticoccidia drug and garlic) in a 2x2 factorial arrangement. Data were collected on growth performance, faecal microbial population and carcass yield and analysed using ANOVA. Result showed that neither sex nor feed supplement had significant (P>0.05) effect on the growth performance of weaner rabbits. Coccidial load was progressively and completely eliminated in bucks and does from the baseline population of 1680epg and 600epg, respectively with rabbits fed diet supplemented with garlic. Also, does fed diet supplemented with commercial coccidiostat had complete coccidial load elimination from 5200epg at 8th week to the 16th week. Helminthic load (3800epg) recorded with bucks fed diet supplemented with garlic at the beginning of study were totally eliminated at the end of the study (56d).
