Abstract The diversity of Pseudo-nitzschia (Bacillariophyceae) and accumulation the neurotoxin domoic acid (DA) in two types shellfish; tuberculate cockles (Acanthocardia tuberculata) sweet clams (Challista chione) was explored M’diq Bay,Morocco during 2007. highest abundances were found period from March to October, with peaks occurring May September. Toxin analysis showed an shellfish sampled spring autumn. maximum toxin concentration 4.9 mg DAg-1 whole tissue recorded clam spring. Using...
The interplay between environmental, biological, and physical factors often leads to the deterioration of dead fish in marine cages prior their removal. Depending on weight frequency removal, can progress a stage where visual identification by divers becomes challenging, thereby disrupting accurate counting fish. This study presents practical precision tool for monitoring number during pregrowth growth phases caged European sea bass ( Dicentrarchus labrax ). To improve assessment collected...
A study of spat settlement two mussel species was carried out in Agadir area on the North Atlantic Coast, between Jan 2002 and 2003. The preferred depth period both were monitored collectors suspended offshore at three different depths (1, 5, 10 m). For Perna perna, effect season consistent, with relatively higher spring (286-462 spats.m-1 ) summer (406-594 ). Similar abundances settlers found 1 m 5 whatever season, which suggests a homogeneous distribution P. perna first sea water. Mytilus...
The feasibility of growing red seaweed, Gracilaria gracilis (Gigartinales, Rhodophyta) in off-bottom and floating longline systems was investigated Bouareg location.The weight gains G. cultures tested winter were low.The lowest daily growth rate (DGR) recorded sheet-lines (1.91 % day -1 , p < 0.01) while the highest"s RGR observed net-lines ropes-lines (2.72 2.77 respectively, 0.01).Plants grew well culture at spring.The rates ranged between 2.54 4.26 .The highest Nador lagoon treatment...
Globally, aquaculture contributes to sustainable food and nutritional stability. However, stress conditions constitute a major threat affecting farmed-fish welfare fish farms’ performances. In this regard, the present study was aimed at measuring comparing in-situ (offshore) physiological responses caused by recurrent sampling operations for length−weight measurement. Studied were European sea bass Dicentrarchus labrax sub-adults adults reared in intensive farming M’diq Bay, on Moroccan...
This article reviews the development potential of Aquaponics in Morocco, an emergent approach which integrates aquaculture with Hydroponics, whereby effluent is used to fertilise plants hydroponic system. subject alternative solution earth modern problems, linked climate change, such as drought, soil degradation, food and water availabilities, negative impact on environment, use chemicals pharmaceuticals. production system has gained interest past five years, however, there yet be successful...
Cost production and profitability analysis was performed for a marine fish farm, located in M’diq Bay, Morocco. Currently, it is the alone farm operation on Moroccan Mediterranean cost while three others had been ceased their activity. Created 1998, has experienced main periods during its history, start-up period, followed by crisis period recovery which present study focused on. Production costs shown financial results yielding very low (0.24%). Two constraints were found to be relevant,...
The objective of this study was to assess the biologic impact four diets based on three species microalgae Mediterranean mussels Mytilus galloprovincialis. For purpose, flesh weight, linear growth, survival rate and biochemical composition mussel have been evaluated. Mussels fed with a mixture species; Nannochloropsis sp., Dunaliella Phaeodactylum exhibited highest lipid level (7.66%). This suggests that mixing several in same diet favors production. Protein significantly higher sp. (28.92%)...
Environmental conditions such as temperature, planktonic biomass, and ocean currents play an important role in the development distribution of marine species. This work aims to estimate, a high spatial resolution, actual trends sea surface temperature (SST) chlorophyll-a concentration (Chl-a) assess relationship with local hydrodynamic Alborán Sea. To investigate these objectives, time series SST Chl-a satellite sensor data were analyzed during 20 years from January 2001 December 2020, using...
Dentex juveniles of initial live weight 5 - 6 g and 108 days old after hatching, were fed three different diets for ten weeks (moist pellet (MP), imported dry pellet (IDP) locally pellet (LDP)) containing lipid levels (26, 21 10% respectively) crude protein (46, 45 47% respectively). Fatty acid composition showed that, DHA EPA contents moist pellet are higher than those of imported pellets. DHA/EPA ratios muscle 1.04 ± 0.00 (MP), 1.48 0.57 (IDP) 0.72 0.05 (LDP). They increased in fact during...
The present study aimed to quantify and compare in situ the primary secondary physiological stress responses, related changing operations of floating net cages, both subadult (523 days post hatching [dph]) adult (916 dph) European sea bass Dicentrarchus labrax under intensive farming conditions Moroccan M'diq Bay. blood levels cortisol, glucose, total cholesterol, protein, lactate, as well percentage haematocrit, were measured before after this operation. results showed significantly...
The molluscan assemblages inhabiting the coastal waters of Oualidia Lagoon, Morocco, were studied during winter and summer 2013. taxonomic composition diversity determined at 43 sample sites. Thirty-four mollusc taxa recorded in total, including 12 species bivalves, 20 gastropods, 1 polyplacophoran cephalopod. Twenty-six these are reported here for first time Lagoon. gastropod Peringia ulvae bivalve Abra alba most abundant both seasons. deposit-feeder trophic group was highly dominant A...
The present study aimed at studying ecological interaction between a fish farm cages located in M’diq bay, western Moroccan Mediterranean coast, and its local environment. It was carried out 2013 2016 through seabed analysis terms of organic matter some nutrients parameters such as Nitrogen Phosphorus, well monitoring macro-fauna assemblages. results showed recorded values relatively stable three years’ interval have well-integrated farming activity within ecosystem. Sediment sandy to shelly...
Spat supply for mussel farming in Morocco is essentially based on seed capture and collection from natural beds. However, irregularity recruitment exploited areas encountered difficulties during spat operations have led to develop improve reproduction techniques under controlled conditions hatcheries. The present study focused the larvae phase aiming at assessing growth rate varies between different development stages. Trocophore larva stage had a size of 63.25 μm reached pedivilegere with...
In hatcheries, meagre Argyrosomus regius larvae still depend on an adequate supply of rotifers and Artemia, as no artificial diet can totally fulfil their nutritional requirements. However, production live feed is highly expensive demands intensive labour specific facilities. This study investigated the effect a dietary regime without use rotifers, to simplify larval rearing protocol. Two feeding treatments (T1 & T2) are compared investigate effects survival growth larvae. T1, were fed from...
Abstract The present study assesses the carbon footprint of only operating marine fish farm in Morocco. Five years data were used to assess its footprint, following ISO/TS 14067 standard, PAS 2050 and IPCC 2006 guidelines. obtained ranged from 2.34 2.85 kg CO 2 e/kg. emission value for 2017 is 38% lower than highest value. Fish feed contributes most farm. Based on 2050, inshore cage farming product ranks same category as dairy products. Furthermore, comparison showed that it almost 67% other...
