“…Due to hydrodynamic systems, the environmental parameters could also cause impacts on the adjacent waters. According to Pérez et al [34], cage culture feed waste could impact a region of 20.6-22.6 ha with the fluxes of 1.9-2.8 kg m −2 year −1 , whereas the total waste could impact a region of 21.8-27.5 ha with fluxes of 3.0-3.4 kg m −2 year −1 . However, the accumulation and impacts of waste from mariculture are dependent on the water exchanges of shallow waters, and close, semi-open, and open water [8].…”

“…These impacts could be chemical accumulations (e.g., heavy metals, antifouling biocides, aquaculture medicinal products, polycyclic aromatic hydrocarbons, and warfare agents by anthropogenic inputs) [9][10][11][12][13][14][15], nutrient loads [8,11,12,16,17], organic matter deposited in sediment [11,12,18], and habitat destruction [8,19,20] as well as negative interaction of invasive species with wild fish [21,22]. Aquaculture is also known to cause an increase in eutrophication [23][24][25][26][27] and algal blooms [28][29][30][31] in coastal waters, a reduction in dissolved oxygen in seawater [32], and expanded dead zones for coastal waters [33,34]. In addition, the increased culture in coastal waters could overload the environmental carrying capacity [35] and cause outbreaks of diseases [36][37][38].…”

Environmental Concerns for Sustainable Mariculture in Coastal Waters of South-Central Vietnam

Mariculture provides an increasing seafood supply to a growing population. It also brings unintended consequences for the environment, resources, and sustainable development. In an attempt to evaluate the impacts of intensive mariculture of lobster in cages, the water quality and sediment quality in three South-Central regions of Vietnam, Xuan Dai Bay, Van Phong Bay, and Cam Ranh Bay, were monitored from April 2019 to May 2020. In each bay, two stations in the farming areas were compared to a non-farming reference station. The result showed no significant differences in the water quality parameters among the stations within each bay and between the bays. However, sediment quality noticeably differed between sites within each bay and between the bays. The accumulation of the observed parameters of sediment in farming areas was higher than in non-farming areas. In the Cam Ranh Bay, the concentration of organic carbon, total nitrogen, and total phosphorus in the sediment in farming areas was approximately 1.4 times higher compared to non-farming areas. Similar results were found in Van Phong Bay and Xuan Dai Bay with different magnitudes. Additionally, the difference in the sulfide concentration in the sediment of Van Phong Bay was notable for its better environmental quality than the other two. The findings indicated that mariculture wastes would accumulate in the sediment, and decompose over time, causing sediment degradation, which may affect the benthic biota in coastal waters.

The physiological response of two species of mussels (Mytilus edulis and M. galloprovincialis) and two species of oysters (Crassostrea gigas and Ostrea edulis) to temperature, oxygen levels and food concentration, factors likely to vary as a result of climate change, was determined experimentally. Bivalves of similar size from different origins were exposed to six temperatures (3, 8, 15, 20, 25 and 30 °C) at two food regimes (2 and 10 μg Chl a L−1) for 6 weeks. In a parallel running experiment M. edulis from the same batches were exposed to three different temperatures (15, 20 and 25 °C) and three different oxygen levels (30, 50 and 100%) at two food regimes (2 and >8 μg Chl a L−1) for 3–4 weeks. Survival during the experiment ranged from 93% to 100% except for the mussels exposed to 30 °C which showed 100% mortality after three to 32 days. Higher food conditions showed higher optimal temperatures for growth of mussels and oysters. In addition, at the high food treatment, reduced O2 saturation resulted in lower growth of mussels. At the low food treatment there were no differences in growth among the different O2 levels at the same temperature. At high food concentration treatment, M. edulis growth was higher with low temperature and high oxygen level. Condition index was higher at higher food concentrations and decreased with increasing temperature. In addition, condition was lower at low oxygen saturation. Lower clearance rates were observed at high food concentrations. At 100% saturation of oxygen, mussel clearance rate increased with temperature at High food regime, but not at Low food regime. Mussel clearance rates were significantly reduced with low oxygen concentrations together with high temperature. Oxygen consumption significantly increased with temperature. Oxygen saturation was the main factor affecting mussel clearance rate. High temperature and low oxygen concentration combined significantly reduced clearance rate and increased oxygen consumption. These response curves can be used to improve parameterisation of individual shellfish growth models taking into consideration factors in the context of climate change: temperature, food concentration, oxygen concentration and their interactions. The observation that abiotic factors interact in affecting mussels and oysters is an important result to take into account.

“…For instance, the ABC model considers pathogen interactions with stocking biomass and predicts mortality due to disease. 78 In some pond FSMs, additional losses related to cannibalism or interspecific predation are also simulated using predator-prey relationships in a population dynamics model. 35 In other FSMs, the additional loss rate is essentially used to adjust farm-production efficiency as a function of different rearing practices (e.g.…”

“…Harvest rates (expressed as a number or percentage of individuals per unit time) and frequency may form part of input data, 73 or harvesting can be triggered automatically when a targeted market size/weight of the animals is reached. 71,[76][77][78] Inter weight distribution due to genetic variability is usually studied. This variability also influences fish ingestion and assimilation capacity, survival and waste emissions.…”

Models are important tools to address sustainability challenges associated with developing aquaculture at farm, regional and global scales. Farm-scale models (FSMs), which are integrated mathematical models developed to simulate farm operations, can quantify energy, mass or economic input flows and predict a variety of outputs such as fish biomass, waste and by-products. The variety of farming systems, equa-
