Parasites, causing little apparent damage in feral fish populations, may become causative agents of diseases of great importance in farmed fish, leading to pathological changes, decrease of fitness or reduction of the market value of fish. Despite considerable progress in fish parasitology in the last decades, major gaps still exist in the knowledge of taxonomy, biology, epizootiology and contr...
For several years, there has been continuing interest in identifying and developing ingredients as alternatives to fish meal for use within aquafeeds (Hardy, 1995; Tacon et al., 1998). Originally, the impetus for this was the often-variable nature of the price and supply of fish meal of suitably high quality for the aquafeed industry. Recently, however, the concern raised about the negative imp...
The workshop on Three Rs Approaches in the Production and Quality Control of Fish Vaccines aimed a) to identify animal tests currently stipulated for the production and quality control of fish vaccines and to highlight animal welfare concerns associated with these tests; b) to identify viable options to replace, reduce, and refine animal use for fish vaccine testing; and c) to discuss the way f...
The Offshore Aquaculture Consortium (OAC) was created as a collaborative, Gulf-wide, interdisciplinary research and development program in response to the U.S. Department of Commerce Aquaculture Policy. OAC research has demonstrated numerous components of offshore aquaculture in the Gulf of Mexico including permitting requirements, mooring systems, cage/mooring survival during several hurricane...
Adequate glazing (6-10%) of fish fillets prior to frozen storage protects the final product from dehydration, oxidation and quality loss. Excessive glazing (>12%) on the other hand may significantly affect the economic value and end user satisfaction of frozen fish fillets. This paper describes the optimization, validation and application of a gravimetric procedure for the quantification of the...
Formalin is an effective solution for surface and equipment disinfection and also for several aquaculture industry challenge. Since various aquatics have different sensitivity to this substance, determination of a precise concentration for cultured fish is important. Because of diversity in aquarium fish species, this topic more highlights. In this study, the method of The Organisation for Econ...
The objective of the work was to develop a non-invasive methodology for image acquisition, processing and nonlinear trajectory analysis of the collective fish response to a stochastic event. Object detection and motion estimation were performed by an optical flow algorithm in order to detect moving fish and simultaneously eliminate background, noise and artifacts. The Entropy and the Fractal Di...
The enzymatic transesterification of ethyl ferulate (EF) with fish oil from cod liver was investigated with Novozym 435 as catalyst under solvent-free conditions. The purpose of the study is to evaluate the synthesis system for the production of feruloyl fish oil in industry. The modified HPLC method was first set up to characterise the reaction products together with liquid chromatography elec...
Aquaculture, one of the fastest growing food producing sectors, is gaining momentum in several parts of the world. Diseases in fish constitute one of the most important problems and challenges for aquaculturists. Hence, aquaculturists undertake good management practices to ensure the production of healthy fish. Intensification has become a common practice in both finfish and shellfish culture t...
