TL;DR: In general, surface sediments of Zhelin Bay were dominated by marine derived organic carbon; this form of carbon was separately calculated based on δ13C-based two end-member mixing and C/N ratio models.

TL;DR: Results showed that G. lichenoides was efficient at absorbing inorganic nitrogen and inorganic phosphate, and maintained a more stable dissolved oxygen level, and Gracilaria spp.
Abstract: A study was conducted in Xiangshan Bay, Ningbo, China, using red alga Gracilaria lichenoides to alleviate nutrient pollution in shrimp (Litopenaeus vannamei) and fish (Epinephelus awoara) culture ponds. Our results showed that G. lichenoides was efficient at absorbing inorganic nitrogen (IN) and inorganic phosphate (IP), and maintained a more stable dissolved oxygen (DO) level. A total of 506.5 kg (1,013 kg ha−1) of shrimp and 210.5 kg (421 kg ha−1) of fish were harvested from the shrimp/algae (SA) and fish/algae (FA) ponds, respectively. Only 53.5 kg shrimp were harvested from the shrimp pond without Gracilaria (S) due to anoxic asphyxia, and 163 kg fish were harvested from the fish culture pond without Gracilaria (F). Compared with using microalgae, bioremediation by macroalgae has no risk of harmful algal blooms (HABs), and it is easy to control seaweed biomass. During the experiment, there was a better environmental condition (lower chemical oxygen demand, IN, IP and chlorophyll a concentrations) in the ponds with Gracilaria. Furthermore, Gracilaria spp. can be used as food for abalone or other aquacultured animals and thus enhance economic return.

TL;DR: In this paper, the main obstacles and risks hindering the growth and expansion of marine aquaculture, as well as the needs and recommendations to overcome such constraints are determined, based on results obtained from a consultation process held in 16 study sites located around the world with the participation of 614 stakeholders representing the research community, aquaulture industry, government, conservation groups, and education and fishermen associations.
Abstract: Marine aquaculture is the most promising industry for ensuring future provision of
seafood. Yet, the worldwide growth and expansion of this industry have been slower than expected, calling for the identification of environmentally suitable sites while accounting for all factors that could constrain or benefit its establishment. Here, we determine the main obstacles and risks hindering the growth and expansion of marine aquaculture, as well as the needs and recommendations to overcome such constraints. Our analysis is based on results obtained from a consultation process held in 16 study sites located around the world with the participation of 614 stakeholders representing the research community, aquaculture industry, government, conservation groups, and education and fishermen associations. A high level of commonality exists in the main issues hindering aquaculture growth and expansion in coastal, off-the-coast and offshore aquaculture with most being attributed to interactions with other maritime activities, including conflicts with other users and administrative procedures,
including licensing. Critical needs for improved management and expansion
of the aquaculture industry are related to planning andmanagement of developments and technological advances, with economic and market needs featuring to a lesser extent. Key procedures recommended to assist further aquaculture growth are th standardisation and simplification of regulatory frameworks, improvement of governance, and the adoption of participatory processes to facilitate meaningful and productive stakeholder engagement. We strongly recommend stakeholder participation to enhance insights on the full environmental and human dimensions of marine management and for implementation of ecosystem-based marine spatial planning.

TL;DR: The levels of serum triglyceride and cholesterol in crowding stress with high density were significantly decreased compared with the control group at 48 h, and hepatic HSP70 mRNA levels were markedly elevated at all stressed groups.
Abstract: Physiological responses and HSP70 mRNA expression to short-term crowding were tested in juveniles genetically improved farmed tilapia (Oreochromis niloticus) (70.43 ± 4.43 g). Fish were kept at control group (5 g L−1) and stress groups (low density 10 g L−1, medium density 40 g L−1 and high density 70 and 100 g L−1) for 48 h. Each density was tested in triplicates. The effects of a short-term exposure on the physiological responses of fish were determined before stress (0 h) and at 6, 12, 24 or 48 h post-crowding. There was a significant increase in serum cortisol, total protein, lysozyme and aspartate aminotransferase (AST) activities in all stressed groups at 24 h post-crowding (P < 0.05). Serum glucose and alanine aminotransferase (ALT) of 100 g L−1 stressed group were lower than that of the control after 48 h of crowding stress (P < 0.05). The levels of serum triglyceride and cholesterol in crowding stress with high density were significantly decreased compared with the control group at 48 h. The mRNA expression data showed that hepatic HSP70 mRNA levels were markedly elevated at all stressed groups. HSP70 mRNA levels of 70 and 100 g L−1 stressed groups decreased at 48 h compared with the 24 h post-crowding. The protective ability of HSP70 was limited.

TL;DR: The embryo–larva migration style of the two species likely shows convergence of non-related species for a common style in response to environmental selection in the Amur River.
Abstract: We conducted laboratory experiments with kaluga, Huso dauricus, and Amur sturgeon, Acipenser schrenckii, to develop a conceptual model of early behavior. We daily observed embryos (first life phase after hatching) and larvae (period initiating exogenous feeding) to day-30 (late larvae) for preference of bright habitat and cover, swimming distance above the bottom, up- and downstream movement, and diel activity. Day-0 embryos of both species strongly preferred bright, open habitat and initiated a strong, downstream migration that lasted 4 days (3 day peak) for kaluga and 3 days (2 day peak) for Amur sturgeon. Kaluga migrants swam far above the bottom (150 cm) on only 1 day and moved day and night; Amur sturgeon migrants swam far above the bottom (median 130 cm) during 3 days and were more nocturnal than kaluga. Post-migrant embryos of both species moved day and night, but Amur sturgeon used dark, cover habitat and swam closer to the bottom than kaluga. The larva period of both species began on day 7 (cumulative temperature degree-days, 192.0 for kaluga and 171.5 for Amur sturgeon). Larvae of both species preferred open habitat. Kaluga larvae strongly preferred bright habitat, initially swam far above the bottom (median 50-105 cm), and migrated downstream at night during days 10-16 (7-day migration). Amur sturgeon larvae strongly avoided illumination, had a mixed response to white substrate, swam 20-30 cm above the bottom during most days, and during days 12-34 (most of the larva period) moved downstream mostly at night (23-day migration). The embryo-larva migration style of the two species likely shows convergence of non-related species for a common style in response to environmental selection in the Amur River. The embryo-larva migration style of Amur sturgeon is unique among Acipenser yet studied.
