Xiphopenaeus Kroyeri
unuftp.is Final Project 2018 Sustainable Management of Guyana’s Seabob (Xiphopenaeus kroyeri.) Trawl Fishery Seion Adika Richardson Ministry of Agriculture, Fisheries Department Co-operative Republic of Guyana [email protected] Supervisors: Dr. Pamela J. Woods Dr. Ingibjörg G. Jónsdóttir Marine and Freshwater Research Institute Iceland [email protected] [email protected] ABSTRACT Seabob (Xiphopenaeus kroyeri) is the most exploited shrimp species in Guyana and the largest seafood export. This species is mostly caught by seabob trawlers, sometimes with large quantities of bycatch. The goal of this paper is to promote the long-term sustainability of marine stocks impacted by this fishery, by analysing 1) shrimp stock status, 2) the current state of knowledge regarding bycatch impacts, and 3) spatial fishing patterns of seabob trawlers. To address the first, the paper discusses a stock assessment on Guyana`s seabob stock using the Stochastic Surplus Production Model in Continuous-Time (SPiCT). The model output suggests that the stock is currently in an overfished state, i.e., that the predicted Absolute Stock Biomass (Bt) for 2018 is four times smaller than the Biomass which yields Maximum Sustainable Yield at equilibrium (BMSY) and the current fishing mortality (Ft) is six times above the required to achieve Fishing Mortality which results in Maximum Sustainable Yield at equilibrium (FMSY). These results indicate a more overfished state than was generated by the previous stock assessment which concluded that the stock was fully exploited but not overfished (Medley, 2013).To address the second goal, the study linked catch and effort data with spatial Vessel Monitoring System (VMS) data to analyse the mixture of target and non-target species within the seabob fishery. -

Aspects of the Reproductive Biology and Characterization of Sciaenidae Captured As Bycatch in the Prawn Trawling in the Northeastern Brazil

E-mail: [email protected] ABSTRACT. The Brazilian prawn fishery, as other bottom trawling fisheries, is considered quite efficient in catching the target species but with low selectivity and high rates of bycatch. The family Sciaenidae prevails among fish species caught. The study was conducted in the Pernambuco State (Barra de Sirihaém), northeastern Brazil. From August 2011 to July 2012, 3,278 sciaenid specimens were caught, distributed into 16 species, 34.2% males and 41.5% females. Larimus breviceps, Isopisthus parvipinnis, Paralonchurus brasiliensis and Stellifer microps were the most abundant species. The area was considered a recruitment and reproduction area with the highest reproductive activity between December 2011 and July 2012. The constant frequency of mature I. parvipinnis and S. microps in catches throughout the year suggests that these species are multiple spawners and use the area during their reproductive period. Since most individuals caught as bycatch have not reached sexual maturity, evidencing the need for a better monitoring of the area and the Sciaenidae caught as bycatch, once this incidental caught can cause fluctuations in the recruitment, increasing the proportion of immature individuals in the population and negatively affecting the reproductive success of the species. -

An Ecological Study of Georgia Coastal Fishes
AN ECOLOGICAL STUDY OF GEORGIA COASTAL FISHES MICHAEL D. DAHLBERG' ABSTRACT The distribution of fishes in relation to ecological factors was studied in a Georgia estuary and adjoining beach and coastal plain creek waters to establish fundamental base lines for the ecology of a relatively undisturbed section of the coast. The distributions of 168 fish species were related to nine recognizable habitats, temperature, and salinity. Length frequencies and spawning seasons were determined for most of the trawled species that contributed significantly to fish production in the estuary. Collecting by a variety of techniques permitted evaluations of types of life cycles, of diversity in the various aquatic habitats, and of distribution patterns within the estuarine complex and adjoining waters. Numbers of species collected in nine aquatic habitats were as follows: beach - 114, lower reach of the estuary - 100, high marsh - 56, upper and middle reaches - 61, oligohaline creek - 40, fresh water - 39, tidal canal - 22, low salinity tidal pool - 22, high-salinity tidal pool - 37.

These nematodes were firstly identified as D. (C.) elongatus (Törnquist, 1931), a commonly reported species from M. furnieri in South American Atlantic waters. However, other species of Dichelyne have so far been reported from this host in the same area, namely D.(C.) rodriguesi (Pinto, Fábio et Noronha, 1970), D.(C.) amaruincai (Freitas, Vicente et IbaZez, 1969) and D.(Dichelyne) micropogonii Pereira et Costa, 1996. A careful re-examination of these parasites, as well as of type specimens of all species reported from M. furnieri, revealed that these nematodes represented a new species. The new species is distinguished from most of its congeners by having papillae 5–7 and 9 forming a subventral line close to cloaca, this feature is shared with other 6 species [D.
