Effects of Replacing Soybean Meal with Sunflower Meal or Fermented Sunflower Meal on the Growth Performance, Intestinal Microbiota, and Intestinal Health of Tilapia (GIFT, ).

A 9-week feeding trial was conducted to evaluate the effects of replacing soybean meal (SBM) with sunflower meal (SM) or fermented sunflower meal (FSM) on the growth performance, intestinal microbiota, and intestinal health of genetically improved farmed tilapia () (initial weight 6.55 ± 0.01 g).

Physiological and microbiome adaptation of coral in response to marine heatwaves.

Against the backdrop of global warming, marine heatwaves are projected to become increasingly intense and frequent. This trend poses a potential threat to the survival of corals and the maintenance of entire coral reef ecosystems. Despite extensive evidence for the resilience of corals to heat stress, their ability to withstand repeated heatwave events has not been determined.

DNA barcoding the ichthyofauna of the Beibu Gulf: Implications for fisheries management in a seafood market hub.

The Beibu Gulf in China is situated in the tropics, in the western Pacific Ocean. It is an emblematic region combining proximity to a marine biodiversity hotspot and a major seafood hub. Intensification of marine fishing and ocean warming led to a drastic decline in fish populations in the Beibu Gulf during the last decades.

Population genetic diversity and structure of (Gobiidae) in Taiwan: Translocation and release.

is a freshwater goby distributed in north, northwest, west, and south Taiwan, but this species has been introduced to east Taiwan and became dominant. To investigate its native population genetic diversity and structure and evaluate the sources and diversity of translocated populations, the mitochondrial DNA control region and cytochrome gene (1981 bp) from 220 specimens were analyzed. These results indicated that (1) the east populations originated from two sources in west Taiwan; (2) translocated populations exist in east Taiwan and south Taiwan; (3) many populations have likely been moved secondarily by human intervention; (4) the effective size of the populations had declined greatly; (5) within the native populations, the ancestral populations colonized Taiwan during the land bridge phase in the Pleistocene through north Taiwan; (6) the landform changes in Taiwan shaped the population structure; and (7) the landforms of the coastline during glaciation also shaped the native range.

RNA-seq analysis reveals divergent adaptive response to hyper- and hypo-salinity in cobia, Rachycentron canadum.

Salinity is an important abiotic stress that affects metabolic and physiological activities, breed, development, and growth of marine fish. Studies have shown that cobia (Rachycentron canadum), a euryhaline marine teleost fish, possesses the ability of rapid and effective hyper/hypo iono- and osmoregulation. However, genomic studies on this species are lacking and it has not been studied at the transcriptome level to identify the genes responsible for salinity regulation, which affects the understanding of the fundamental mechanism underlying adaptation to fluctuations in salinity.

Genetic evidence for the mating system and reproductive success of black sea bream ().

Understanding the mating system and reproductive success of a species provides evidence for sexual selection. We examined the mating system and the reproductive success of captive adult black sea bream (), using parentage assignment based on two microsatellites multiplex PCR systems, with 91.5% accuracy in a mixed family (29 sires, 25 dams, and 200 offspring).
