Abstract

Aquaculture growth is expected to continue to increase until it, intensification of vanamei shrimp culture is one of the best possibilities for increasing aquaculture production. Limited supply, price, and environmental factors are issues in meeting the needs of fish meals in feed. This study aimed to evaluate the effectiveness of nucleotides (NT, Nucleoforce AquaTM, Bioiberica, SAU, Spain) as feed additives available commercially in optimizing feed formulations from plant-based ingredients in the production of Pacific white shrimp (Litopenaeus vannamei). A 60-day growth trial was conducted to evaluate five dietary treatments: Basal-1 with 10% fish meal; Basal-2 with 6% fish meal; Diet-1: 10% fish meal+0.1% NT; Diet-2:8% fish meal+0.1% NT and Diet-3: 6% fishmeal+0.1% NT. Results showed that the inclusion of 0.1% nucleotide into the diet formulation has been able to provide good results. Adding nucleotides provides better performance and significantly increases the final biomass, final individual body weight (FBW), feed conversion ratio (FCR), feed protein retention, and average daily growth (ADG) (P<0.05) and thermal growth coefficient (TGC). The best results is Diet-1 (10% FMNT treatment) with the best protein content of 37.06% ± 0.15, showed the best performance of growth parameters (ADG, FBW, SR, TGC, PER, and RP) and lowest FCR. The addition of 0.1% nucleotide proves that the functional and nutritional properties of NT have many advantages in increasing the growth rate and more efficient in protein absorption. Therefore, 0.1% NT can be recommended as a supplement in shrimp feed.

Abstract

The commercially important red seaweed Kappaphycus alvarezii is extensively cultivated for carrageenan production. Despite its economic value, large-scale reproduction and genetic enhancement remain limited due to its low regeneration potential. This study aimed to optimize plant growth regulator (PGR) concentrations for efficient callus induction in K. alvarezii. A completely randomized design was employed, comprising five treatments with varying concentrations of indole-3-acetic acid (IAA) and 6-benzylaminopurine (BAP), along with a control lacking PGRs. A total of 180 explants from meristematic tissues of acclimatized thalli were cultured (30 explants per treatment). The highest callus induction rate (88%) was achieved with 1.50 mg/L IAA and 5 mg/L BAP (Treatment F), with visible callus formation beginning around day 38. A progressive color change from brown to white was observed, indicating active cellular proliferation. Other treatments exhibited lower induction rates, ranging from 0% (control) to 61% (Treatment D). These findings underscore the critical influence of auxin–cytokinin interactions on callogenesis and offer an optimized hormonal regime for improving in vitro culture efficiency. The established protocol provides a valuable platform for future large-scale propagation and genetic improvement strategies in K. alvarezii, contributing to the advancement of seaweed biotechnology.
