Abstract Insect meals are sustainable alternative protein sources in animal nutrition. However, the data in the topic of their application in petfood and ornamental fish nutrition are scarce. Thus the present study was undertaken to asses their usability in guppy (Poecilia reticulata) diets. The first experiment aimed to investigate the attractiveness of select insect meals for guppies, and the second in evaluation of superworm (Zophobas morio) meal monodiet effects. The first experiment (free-choice feeding test) lasted five days. Fish were given a choice between four attractants: fish meal, black soldier fly (Hermetia illuces) meal (HI), Madagascar cockroach (Gromphadorhina portentosa) meal (MC), and superworm (Zophobas morio) meal (ZM). The preliminary part of the study showed that the most frequently chosen attractant throughout the entire free-choice feeding test period was ZM. Based on the obtained results, the second part of the study was designed as a growth test with the use of a ZM monodiet compared to commercial feed. The experiment lasted 90 days, and 150 guppy fry were used. The fish were randomly divided into two groups (CON - commercial feed, ZM - Zophobas morio meal). No effects of dietary treatment were found in terms of survival rate, fish body length, or fish body length gain. The present study shows that ZM was the most preferred attractant and that a monodiet based on insect meal can be successfully applied in guppy fry nutrition.

Quail is one of the potential sources of animal protein from poultry as egg producers. An egg contains complete nutrients, namely protein, fat, vitamins, and minerals. As food, eggs must be maintained both physically and chemically to be safe for consumption. This study aimeds to examine the effect of selective feeding on the quality of quail eggs. This research was carried out at Percut Sei Tuan Subdistrict, Deli Serdang Regency, North Sumatra, which had been implemented from August to November in 2018. The study used a completely randomized design with 4 treatments and 5 plots. The study used egg samples from quail aged five (5) months. The treatment consists of Commercial feed (T0), 2 energy source feed (rice bran, corn) with 2 (T1), 3 (T2), 4 (T3) protein source feeds (fish meal, soybean meal, coconut meal, Poultry Meat Meal). The results showed that the treatment gave a significant effect (P<0.05) on egg weight, albumen, and eggshell weight, commercial feed showed eggs weight higher than free choice feeding treatments, while among free choice feeding treatment did not show significant effect. The free choice feeding treatment has a significant effect on the yolk weight, where T2 has the lowest yield. Percentage of yolk, albumen, quail eggshell and egg index, egg yolk index, albumen index, haugh unit and quail yolk color did not show significantly different (P>0.05) among treatment. It can be concluded that the commercial feed showed higher egg weight but had no significant effect (P>0.05) on the proportion of eggs and the interior quality of quail eggs, while among free choicee feeding treatment has no effect.

Abstract The present study aimed to evaluate the feeding performance of juvenile marble goby (Oxyeleotris marmorata) on acidified diets. Five fish meal-based diets at various pH levels (2.5, 3.2, 4.3, 5.3, and 6.0 (control)) were prepared, and each of them was fed to 10 wild-caught O. marmorata juveniles (body length 7.7–9.3 cm; each fish was placed in an aquarium, hence each dietary treatment was in 10 replicates) for 20 days. Throughout the feeding trial, O. marmorata juveniles showed clear increments in the daily ingestion ratio (IR) values of AD 2.5, AD 3.2, and AD 4.3. The control diet and AD 5.3 were almost totally rejected by the fish. On day 20, the IR of AD 2.5 (0.46) and AD 3.2 (0.36) were significantly higher (P < 0.05) than those of AD 5.3 (0.1) and the control diet (0.02). In addition, 70% of fish fed AD 2.5 achieved a high IR value (0.6 – 1.0), and this was the best result among all the treatments (AD 3.2, 60%; AD 4.3 50%; AD 5.3 and control, 10%). These results suggested that acidified diets can be used to wean O. marmorata juveniles, and the recommended pH level was 2.5.

The demand of fish meal as a protein source of feed increases with the increasing of fish culture activities, so this activities needed alternative protein sources to reduce the use of fish meal. The feed ingredient can be used as an alternative protein source is chicken intestine silage meal. The purpose of this research were to determine the percentage of chicken intestine silage meal to substitute fish meal in feed formulation of catfish fry based on the growth and feed efficiency. This research was conducted in June-July 2014 in the Laboratory of Aquaculture, Aquaculture Program, Faculty of Agriculture, Sriwijaya University. Research methods using Completely Randomized Design with six treatments and three replications (A : commercial feed, B: 0% chicken intestine silage meal and 100% fish meal, C: 25% chicken intestine silage meal and 75% fish meal, D: 50% chicken intestine silage meal and 50% fish meal, E: 75% chicken intestine silage meal and 25% fish meal, F: 100% chicken intestine silage meal and 0% fish meal). Results showed the utilization of chicken intestine silage meal significant effect on growth and feed efficiency, but not significant on survival catfish fry. Utilization of chicken intestine silae meal could substitute 100% fish meal in feed formulation of catfish fry. During the study the water quality is still at normal level for the maintenance of catfish fry.

The continuous demand for alternative protein sources for fish due to its short supply, high prices and competition with the human food. A review of unconventional feeds in fish nutrition was carried out to provide information on supplemental feed for effective Aquaculture. Non-conventional dietary energy and protein sources,especially from plant origin can be used to replace expensive protein sources. There is a continuous demand for alternative protein sources for fish due to short supply, cereals and oilseed mealsfor sustainable aquaculture production. The solid waste materials like distillers dried grain soluble, breweries waste, ghee residue and agricultural plant materials like jute, leucaena, moringa, cassava, rain tree and spirulina can find a place in formulation of aquafeed as one of the inexpensive feed ingredients. The non-conventional feed ingredients to be incorporated in fish feed up to recommended levels.
