Avaliação dos aspectos da dieta alimentar de Pimelodus maculatus em dois importantes tributários do reservatório de Jurumirim, Alto Rio Paranapanema-SP

The species Pimelodus maculatus is one of the most abundant fish in many artificial reservoirs. Shows feeding plasticity and exploits all trophic levels in aquatic ecosystems. This study aimed to analyze and compare aspects of the diet of P. maculatus in two important tributaries (Taquari and Veados rivers) in the upper Paranapanema River system, and also investigate possible differences in the condition factor using its feeding habit as reference. Samplings were carried out every three months during 2011 and 2012 in two tributaries of Jurumirim's dam. After biometric analysis, fish were dissected to remove the stomachs that were fixed in formaldehyde 10% and conserved in alcohol 70%. The stomach content was analyzed under stereomicroscope and the food items were identified until the least possible taxonomic level. The diet was characterized based on the Alimentary Index (IAi). Feeding strategy and aspects of species autoecology were evaluated by the relation between abundance of prey-specific (Pi) and occurrence frequency (Fo) of the prey, and also was calculated the niche width of Levin (B). The condition factor was also established and values obtained in samples of both rivers were compared, correlating them with diet of the species

Segurança alimentar e gestão municipal: uma investigação a partir de comunidade rural assentada em Araraquara

This paper sought to deepen, investigate and analyze the institutional and organizational obstacles of public policies for food security programs, in a period of change in municipal management. Our aim is besides de obstacles, to identify the efficacy and effectiveness of SAN social network, highlighting the National Program of School Food – PNAE. The analysis focuses the city of Araraquara and its food security program network in its relationship with the settlements, highlighting its cultural and productive particularities.

Não preferência para alimentação e antibiose em cultivares de amendoim a Stegasta bosquella (Chambers) (Lepidoptera: Gelechiidae)

This work aimed to evaluate the attractiveness, non-preference for feeding and antibiosis in straight and runner growth habit peanut cultivars to Stegasta bosquella (Chambers). Eight cultivars were evaluated, four of straight growth habit (IAC Tatu, IAC 22, IAC 8112 and IAC 5) and four of runner growth habit (IAC Runner 886, IAC 147, IAC 125 and IAC 503). Free-choice and no-choice feeding tests were performed, using pairs of overlapped leaf discs with 1.0 cm diameter, which were placed in Petri dishes where third instar larvae of S. bosquella were released. The attractiveness to the larvae was assessed in predetermined times, in addition to the dry mass consumed. In the antibiosis assay, the biological parameters were evaluated: period and viability of larvae, pre-pupae, pupae, and total, weight of larvae and pupae, sex ratio and longevity. None of the runner growth habit cultivars exhibited non-preference for feeding-type resistance. Among the straight growth habit cultivars, IAC 5 and IAC 22 were the least attractive and consumed in the free-choice feeding test, and IAC 5 and IAC 8112 were the least attractive in the no-choice test. The runner growth habit cultivars IAC 147 and IAC Runner 886 affected the larval survival of S. bosquella, exhibiting antibiosis-type resistance. For the straight growth habit cultivars, IAC 22 and IAC 8112 affected the larval viability, presenting antibiosis-type resistance. The straight and runner growth habit cultivars did not influence the biological parameters of weight of pupae, sex ratio and longevity of S. bosquella.

Densidade de estocagem e restrição alimentar em juvenis de piapara

The effects of stocking density and food restriction in juvenile piapara (Leporinus elongatus) were studied by two experiments. In the first, 88 piaparas juveniles were stocked in three densities (0.13, 0.20 and 0.40 fish L-1) for 70 days. Were evaluated: weight gain, average consumption, specific growth rate and feed conversion. The experiment was conducted in completely randomized design with three treatments (0.13, 0.20 and 0.40 fish L-1) and four replicates. In the second experiment, 84 fish were divided into three treatments (RBD, with 4 replicates): control group (daily food); FDS group (animals fed on weekends) and Res 21 group (animals subjected to food restriction for 21 days). Highest stocking density resulted highest biomass produced. Fish subjected to food restriction for 21 days and animals fed on weekends group, displayed full compensatory growth.
