The suitability of using discards from artisanal fisheries as feed for wild-caught Chelidonichthys lucerna (L.) reared in submerged cages in the Adriatic Sea was investigated. Three-hundred juvenile tub gurnard (72.9 ± 11 g, 18 ± 1 cm) were captured and separated into four circular 35.3 m3 submerged cages. Two stocking densities were used: two cages contained 60 fish each (1.7 fish m-3; CG-L) and two cages contained 90 fish each (2.55 fish m-3; CG-H). Growth performance and survival rates were recorded over a 240 day period during which tub gurnard were fed with a variety non-target fishery discards, including common crab, sardine, Atlantic chub mackerel, anchovy, and salema. The survival rate was approximately 90% in both groups (CG-L = 91% and CG-H = 90%), with final stocking densities of 0.32 kg m-3 and 0.49 kg m-3 for the CG-L and CG-H groups, respectively. There were no significant differences in final mean body weight or length between the CG-L group (206 ± 23 g, 24.6 ± 2 cm) and the CG-H group (215.5 ± 32 g, 24.8 ± 2 cm). The condition index was similar between the two groups (1.38 and 1.42 for CG-L and CG-H, respectively). The feed conversion ratio was high in both the CG-H (2.39) and CG-L (2.32) cages. These results demonstrate that viable growth rates of tub gurnard may be obtained by feeding recycled fishery discards and rearing in cages placed on the seabed, which allows for the natural benthic behavior of this species.

This study was conducted to evaluate the replacement of fishmeal by black soldier fly larvae (Hermetia illucens) (BSF) meal, frozen beef heart, and commercial pellet on growth performance, survival rate, and feed utilization of discus fish (Symphysodon sp.). Discus juveniles were graded into small, medium and large size groups as block in a completely randomized block design. Five trial diets included frozen beef heart (T1), commercial feed for discus fish (T2) and three diets containing graded levels of BSF as replacements for protein from fishmeal of 0% (T3), 25% (T4), and 50% (T5). The results showed that TAN and nitrite levels in the beef heart treatment were higher than those in the other ones. Moreover, discus fish in treatment 1 had a higher growth rate and a lower feed conversion ratio than those in the other treatments. On the other hand, no statistically significant differences among the pellet treatments were observed for growth rates of discus's weight, length and height and feed conversion ratio (P > 0.05). Moreover, the results showed that discus fish in the two BSF treatments did not suffer from diseases and had higher survival rates than those in the other treatments.

The Impact

This study aimed to examine the impact of dietary salt-based mineral and phosphorus supplements on mean body weight, survival rate, and feed conversion ratio of Litopenaeus vannamei (white shrimp) reared in brackish water. The experiment was performed randomized design with three replicates in each treatment used twelve 40 L rectangular polymethyl methacrylate containers reared 45 days. The four treatments in this study were based on the concentration of salt-based mineral and phosphorus supplements (control or 0 ppm, one ppm, two ppm, and three ppm) in dietary of white shrimp. The results showed that using salt-based mineral and phosphorus supplements in dietary of white shrimp positively impacts mean body weight, survival rate, and feed conversion ratio. Increasing the concentration of salt-based mineral and phosphorus supplements increased mean body weight and survival rate and reduced feed conversion ratio of white shrimp. The mean body weight, survival rate, and feed conversion ratio of white shrimp were achieved with three ppm of dietary salt-based mineral, and phosphorus supplements reared 45 days was 5.98 gr, 88.57%, and 1.45, respectively.

HighlightsLitopenaeus vannamei has been established as alternative to Penaeus monodon to shrimp farming in several countries.Increased importance of in situ microorganisms both in regulating biogeochemical cycles within the culture environment and in directly affecting shrimp growth and survival.To improve water quality in aquaculture is the application of probiotics and/or enzymes to ponds. AbstractIntensive shrimp farming has raised environmental issues due to aquaculture pollution, which is caused by uneaten feed, feces, organic matter, and toxic compounds (ammonia and H2S). One way to solve this issue is by using probiotics. Thus, this study aimed at investigating the effect of probiotic administration (Pseudomonas sp. and Bacillus sp.) at varying concentrations on total organic matter in the rearing water, feed conversion ratio, feed efficiency, and growth rate of white shrimp (Litopenaeus vannamei). This study used a Completely Randomized Design consisting of four treatments: T0 (without the probiotic supplementations), T1 (probiotics at 106 CFU/ml), T2 (probiotics at 107 CFU/mL), T3 (probiotics at 108 CFU/mL) with three replicates each. The results showed that the administration of probiotics at different concentrations had a significant effect on the total amount of organic matter, feed conversion ratio, feed efficiency, and specific growth rate of white shrimp. Administration of probiotics at a concentration of 107 CFU/ ml had the lowest organic matter in the rearing water, 138 mg /Lt. While probiotic administration at 108 CFU/ ml gave the lowest feed conversion ratio (1.22), the highest feed efficiency (81.57%) and the best growth rate (2.25%/day). This research suggests that the administration of 107-108 CFU/ ml probiotics could be applied to reduce organic content in the rearing water and improve the growth performances of white shrimp.

Black soldier fly (BSF) larvae may play a role in a circular economy by upcycling low-value organic streams into high value biomass. In this paper, the capacity of BSF larvae to process 12 organic side-streams (mono-streams) and two standard substrates (chicken start mash and Gainesville diet) was investigated. Survival, larval mass, feed conversion ratio, and waste reduction were evaluated in relation to the proximate composition of the side-streams used. Survival rates larger than 80% were observed for 10 of the organic mono-streams and the two standard substrates. Maximum mean larval weight ranged from 38.3 mg up to 176.4 mg regardless of high survival and was highly correlated with substrate crude protein content. Feed conversion ratio (range 1.58–8.90) and waste reduction (range 17.0–58.9%) were similar to values reported in other studies in the literature. On low protein substrates (e.g., apple pulp), survival rates remained high, however, possibly due to protein deficiency, limited larval growth was observed. It is concluded that several low value organic side-streams can successfully be processed by BSF larvae, thereby opening the possibility of lowering the costs of BSF farming. Potentially mixing nutritionally distinct mono-streams into a mixed substrate might improve BSF performance. However, more research is needed for optimizing diets to guarantee production of BSF larvae of constant yield and quality.

<p><em>The aim of this study was to analyze the survival rate, growth, and haemolymp glucose level of white shrimp as a physiological responses at floating cage cultured on different stock den-sity, in Seribu Islands Strait. White shrimp used in this study contained approximate weight of 1.0±0.06 g and length of 5.0±0.03 cm from Nusa Karamba Hatchery in Seribu Island. White shrimp was maintained in 90 days, feed with ±36.28 % protein content 4 times each day with feeding rate (FR) of 7%. Water qualities and shrimp growth measurements was conducted every 10 days. Haemolymph glucose sam-pling was performed in the beginning and at the end of the experiment. Result showed that treatment with stock densituy of 250 shrimp/m<sup>2 </sup>had a better survival rate of 30.33% and feed conversion ratio of 1.13 than other treatments. </em><em>Phy-siological response in the form of glucose hemolim also showed a better response in the 250 ind./m<sup>2</sup> stock density of 41.87 mg/dl indicating that the white shrimp did not experience a sig-nificant stress. </em></p><p><strong><em>Keywords: </em></strong><em><span style="text-decoration: underline;">Litopenaeus</span> <span style="text-decoration: underline;">vannamei</span><strong>,  </strong>sea floating cages, stock density, strait waters, Seribu Islands.</em></p>
