ALTERNATIVE LIPIDS IN NUTRITION OF MARINE FINFISH
… dietary fatty acid profile. LC-PUFAs in marine finfish are more bioavailable in the context of SFA-/MUFA-rich alternative lipids, thus, reducing the requirements for these nutrients and allowing the fish’s physiological demand to be met with dietary levels below the minimum levels recommended. …

Biosecurity in the Recirculation Sector of Finfish Aquaculture in the United States and Canada
… of biosecurity in the recirculation sector of finfish aquaculture in the United States and Canada. Specifically, this research: 1) identified and characterized finfish recirculation facilities in the United States and Canada; 2) assessed biosecurity utilization in these facilities; 3) examined …

Isolation, Characterisation and Preservation of Bacteriophages for Use in Treatment of Aeromonas hydrophila Infection In Finfish
Problems caused by multidrug resistant bacteria and the limited number of control strategies, highlight the need for alternative control approaches against bacterial infections in the aquaculture sector. Bacteriophages (phages) demonstrated promising results as therapeutic tools, for the effective …

The development of a modular integrated recirculating aquaculture system using Porphyra (nori) for the bioremediation of marine finfish effluent
… aquaculture (IMTA) uses a fed component (e.g. finfish) and an extractive component (e.g. seaweed) to remove the inorganic metabolites from finfish aquaculture effluent. In IMTA systems metabolic wastes become nutrients for the other cultured organisms and are incorporated into potentially …

Impacts of socioeconomic and demographic factors on household expenditure for disaggregate fish and shellfish in the United States
… at-home seafood consumption data for specific finfish and shellfish species by three product forms (canned, fresh and fresh frozen, and other prepared) from the 1981 Seafood Consumption Survey: (i) finfish -- cod, flounder (or sole), haddock, herring, mackerel, perch, pollock, salmon, sardines, …

The wetted ramp as a useful tool to service smaller-bodied finfishes at low-head acquatic barriers
<p>This study examined the effects of finfish length and behavior on passage success on the wetted ramp, a proposed passage device for finfishes at low-head aquatic barriers. There were two hypotheses: there is a size effect to passage success because larger fish have relatively less propulsive …

Modelling the food web in the Irish Sea in the context of a depleted commercial fish community
Irish Sea landings used to be dominated by finfish but now mainly consist of molluscs and crustacea due to stock declines and changing market demands. There has been limited evidence of finfish recovery despite fishing effort reductions, gear restrictions, and area closures. Frustrated and …

Caratteristiche merceologiche, nutrizionali, sensoriali e di freschezza di Nasello (Merluccius merluccius), Lanzardo (Scomber japonicus) e Suro (Trachurus trachurus)
Three finfish species frequently caught in the waters of the Gulf of Manfredonia (Apulia, Italy) were studied in order to know how the flesh composition (proximate, fatty acid, macro- and micro- element contents) could be affected by the season effect. The species we examined were European hake …

Legal aspects of the conservation and exploitation of off-shore living marine resources in Antarctica
… resources found in Antarctic seas. Besides finfish, there appears to be great potential in krill fisheries. Krill are small, shrimp-like crustaceans which swarm in major concentrations in Antarctic waters. Estimates of krill fisheries vary considerably from standing stocks of 125 million …

Identifying genetic variation in candidate genes for heat stress and association thereof with growth performance in dusky kob (Argyrosomus japonicus)
… globally distributed and economically important finfish family, with dusky kob (Argyrosomus japonicus) being the species of interest in South Africa. Unfortunately, the wild populations have collapsed due to decades of overexploitation by commercial and recreational fisheries. Therefore, a shift …

Movement Ecology and Trophic Dynamics in the northern Gulf of Mexico: Implications for Fisheries Management
… to assess the trophic interactions of 41 finfish species and their prey. Many of these species, such as Spotted Sea Trout, Red Drum, Southern Flounder, and Gulf Menhaden, are of significant economic importance to the region. This chapter refines our understanding of the region's trophic …

The Effects of Salinity on Zootechnical Performance of Spotted Seatrout (<i>Cynoscion nebulosus</i>) in Recirculating Aquaculture Systems
… (<em>Cynoscion nebulosus</em>) is a euryhaline finfish candidate for marine aquaculture in the northern Gulf of Mexico. Aquaculture of this species currently uses salinities of 25 psu or greater making production challenging in areas where high salinity water is not available. This study aimed …

Determining the Trophic Role of Gulf Menhaden (<i>Brevoortia patronus</i>) Using Carbon and Nitrogen Stable Isotopes
… many recreationally and economically important finfish. Gulf menhaden also support a large commercial fishery, and little is known about the impact of fishing on the role of this species as a filter feeder in the food web. This study examines the spatial, temporal and ontogenetic dynamics of …

Benthic and Planktonic Microalgal Community Structure and Primary Productivity in Lower Chesapeake Bay
… relevant fauna, including shellfish and finfish populations. While regarded as significant components of coastal environments, microphytobenthic communities are historically understudied. In Chesapeake Bay, the importance of phytoplankton to the ecosystem is understood, but the …

Predicting risks from acoustic deterrents
… noise to deter pinnipeds from predating on caged finfish. However, the<br/>widespread and long-term use of these devices in coastal environments could pose<br/>considerable risks for target (pinnipeds) and non-target (e.g., cetaceans) species which also<br/>inhabit areas adjacent to aquaculture. …

Growth Potential of Young Black Sea Bass, Centropristis Striata, in Artificial Environments
… potential of the commercially important marine finfish, black sea bass (Centropristis striata), was examined for aquaculture under controlled conditions. The effect of food and body weight on growth was evaluated using juveniles and young black sea bass cultured with a natural diet and a …

Understanding the Mechanisms that Determine Feed Conversion Ratio in Chinook Salmon – Physiological and Behavioural Aspects
Finfish aquaculture production costs can be reduced by improving feed conversion ratio (FCR), the ratio of feed intake to weight gain. The aim of this thesis was to identify key factors that influence individual FCR variation in Chinook salmon (Oncorhynchus tshawytscha). Feed efficient and …

Immune and Endocrine Modulations Associated with Enhanced Plant-Based Protein Diets Within Freshwater Fish Species

Fermentation characteristics, nutritional value and palatability of ensiled seafood wastes and low quality roughages
… by ensiling. In a large silo study, mixtures of finfish and crab processing wastes were mixed with wheat straw and ensiled in 210 liter metal drums, double lined with polyethylene bags. Proportions of the fish and straw were 70:30 and 51:49, wet basis, while that of the crab was 60:40 and 40:60. …
