Density-related information for landlocked fall Chinook Salmon Oncorhynchus tshawytscha shortly after first feeding is poorly understood. This study was undertaken to determine the effects of a range of rearing densities (low, intermediate, and high) on rearing performance and survival of newly feed-trained juvenile landlocked fall Chinook Salmon.

ObjectiveAeromonas hydrophila, a leading pathogen of aquatic organisms, poses a significant challenge in terms of effective and safe inhibition.MethodsThrough the method of experiments and molecular simulations, we discovered that emodin effectively inhibits the A. hydrophila via the binding of emodin with AtpE (ATP synthase subunit C). Bacterial inhibition experiments show that emodin effectively inhibits the activity and growth of A. hydrophila.ResultFurther molecular docking and molecular dynamics simulation revealed that emodin binds directly to AtpE. More specifically, it binds to certain residues of AtpE, including TYR73, LEU70, ALA13, TYR10, MET17, and ALA14, ultimately leading to inhibition of activity.ConclusionConsequently, our discovery sheds new light on exploring the molecular mechanism through which emodin displays antimicrobial activity against A. hydrophila.

The sunshine bass (female White Bass Morone chrysops × male Striped Bass M. saxatilis) is an important food fish raised in U.S. aquaculture. Spawning is performed by manually stripping and fertilizing White Bass eggs with Striped Bass sperm. Embryos hatch in approximately 48 h. Mature sunshine bass females can become fertile and produce viable eggs, which is problematic in commercial food-fish production; therefore, triploid fish are desired.
阳光鲈鱼（雌性白鲈鱼 Morone chrysops × 雄性花脸鲈鱼 M. saxatilis）是美国水产养殖业养殖的一种重要食用鱼。产卵是通过人工剥离白鲈鱼卵并使其与花脸鲈鱼精子受精。胚胎大约在 48 小时内孵化。成熟的阳光鲈雌鱼可以受孕并产生有活力的鱼卵，这在商业食用鱼生产中是个问题；因此，需要三倍体鱼。

The Blackbanded Sunfish Enneacanthus chaetodon is a small centrarchid that is endemic to slow-moving waters from New Jersey to central Florida, United States. The distribution of this species has been increasingly fragmented, primarily due to habitat degradation. The development of larval culture protocols is essential to produce this species for the aquarium trade and for potential restoration efforts. To streamline the production process, larvae should be transitioned from live feeds to inert diets as early as possible without sacrificing larval growth or survival.

The Red Shiner Cyprinella lutrensis is one of the most prolific and ecologically destructive invasive fish species in the southwestern United States. The production and release of YY individuals as Trojan sex chromosome carriers can theoretically eradicate invasive fish populations by eventually eliminating phenotypic females.

The antiparasitic effect of peracetic acid (PAA) was evaluated against an infestation of the protozoan Trichodina spp. in naturally infected juvenile domestic seventh generation (F7) Striped Bass, Morone saxatilis. Replicated treatments (n=3) consisted of 1 and 2 mg/L PAA and a control; treatments were applied every other day for 3 treatments (30 min static exposure). Infestation intensity was enumerated 20 - 24 h after each treatment by counting the number of Trichodina present in a wet mount of excised gill tissue. Neither treatment rate was able to completely eradicate the parasite, however 2 mg/L PAA resulted in a statistically significant reduction which equated to 75% reduction of observed parasites. The 2 mg/L PAA treatment regimen in the present study is proposed as a safe, environmentally friendly, and effective method for reducing the intensity of Trichodina infestations in Striped Bass.

Longfin Smelt, Spirinchus thaleichthys, is an imperiled migratory forage fish that is endemic to the west coast of North America. The southernmost distinct population in the San Francisco Estuary, in particular, has experienced dramatic declines in abundance over the past few decades. Diverse strategies are likely needed for effective conservation of Longfin Smelt, with captive breeding and rearing likely to become essential for enhancing population size and preserving genetic diversity. Only recently have significant investments been made to develop a culture program for Longfin Smelt. Here, we report the first successful rearing of laboratory-bred (F1) Longfin Smelt to maturity (at age-1+), followed by the subsequent spawning and production of a second generation (F2) of Longfin Smelt, entirely within captivity. We also describe the culture conditions utilized throughout the complex life cycle of the mature F1 broodstock.
