“…Body mass relationship is usually described by the general power equation DM = aL b , or after logarithmic transformation as log DM = log a + b log L (where: a, b = regression constants, DM = dry mass, and L = length parameters) (Miyasaka et al 2008). To determine dry mass for each species, a representative number of all size classes were selected.…”

a b s t r a c t Lake-outlets are transitional areas recognized as highly productive ecosystems in terms of density and biomass of aquatic insects. Life cycle, secondary production, trophic guilds and environmental constraints of caddisfly assemblages were investigated on a natural lake-outlet stream (Nant y Fall) in Patagonia, Argentina. We investigated the site monthly from May 2007 to April 2008 by recording environmental data and sampling caddis larvae using a Surber sampler at riffle areas (n = 36). Mastigoptila longicornuta, Smicridea annulicornis, Smicridea frequens, Brachysetodes quadrifidus and Parasericostoma ovale displayed well synchronized univoltine life cycles, while Neoatopsyche brevispina, Neopsilochorema tricarinatum, showed an asynchronous development pattern, although most of them had an extended recruitment, similar to those reported for non lake-outlet streams in the area. Annual secondary production per species varied from 8.22 (B. quadrifidus) to 3568.83 mg m −2 y −1 (P. ovale), with overall caddisfly production amounting to 4.8 g m −2 y −1 . Shredder/collector-filterer ratio was 3.3/1 suggesting that the system was detrital based. Redundancy analysis indicated that seasonally dynamic variables such as discharge, benthic particulate organic matter and temperature were the main predictors of seasonal caddisfly assemblage variation. We propose that the variety of food resources and the significant spatial heterogeneity at lake-outlet streams contribute to sustain a rich caddisfly community.

Synchrony, one of the main traits of population life histories, refers to the degree to which individuals complete a certain stage of the life cycle at the same time. It can be governed by temperature, variations in temperature, photoperiodic cues, detritus inputs, or discharge regimes. We investigated life cycles and secondary production of five caddisfly species in a second order stream in the Patagonian Mountains. In addition, we analyzed what environmental variables were implied in the caddisfly assemblage variation. Mastigoptila sp. (Glossosomatidae) and Eosericostoma aequispina (Helicophidae), Myotrichia murina (Sericostomatidae), Brachysetodes quadrifidus (Leptoceridae), and Neoatopsyche brevispina (Hydrobiosidae) showed univoltine life cycles, with an extended recruitment with no overlapping cohorts and a relatively well-synchronized imaginal emergence taking place during spring summer seasons. However, Myotrichia murina (Sericostomatidae) displayed a complex life cycle with mixed populations taking 10-12 months to develop, and pupae being collected almost continuously. The annual secondary production per species varied from 11.06 (E. aequispina) to 310.5 mg m -2 year -1 (M. murina), being overall caddisfly production (0.5 g m -2 year -1 ) similar to that reported for cold springs in other regions. The highest growth rates (K) were observed during late winter and spring (mostly September) and ranged from 0.70 to 3.70% day -1 in M. longicornuta and N. brevispina, respectively. Redundancy analysis indicated that seasonally dynamic variables, water temperature, discharge, and detritus biomass were the main predictors of caddisfly assemblage variation; consequently at this cold stream (mean annual 5.9°C), with a regular availability of food supply, these parameters ruled Trichoptera life histories and secondary production. As documented for other mountainous temperate areas, synchrony would be a dominant trait on life histories of Trichoptera species inhabiting Patagonian streams.

“…Zoo benthic organisms were segregated and stored in 5% formalin solution. Zoo benthic organisms were identified to family level, divided into body length classes and dry matter (DM) biomass estimated per pond area by using DM-length regressions from the literature (Miserendino, 2001;Miyasaka et al, 2008).…”

It was evaluated whether earthworm meal can fully replace fishmeal in supplemental feeds for common carp (Cyprinus carpio) that also feed on natural food resources in semi-intensive aquaculture. A net cage trial (32 nets) was carried out using three iso-nitrogenous feeds fed to common carp either at a level of 10 g/kg 0.8 metabolic body mass (5 fish per cage) or 20 g/kg 0.8 metabolic body mass (10 fish per cage). In feeds, fishmeal protein was replaced by 0 %, 50 % or 100 % of protein from sun dried earthworms (Perionyx excavatus). At both stocking densities, control groups of fish fed only on natural food resources. The growth rate of fish increased with rising replacement of fishmeal by earthworm meal at both feeding rates. Large zooplankton were the predominant natural food resource. With increasing availability of large zooplankton, sun dried earthworm meal in plant-based supplemental feeds seemed better able to meet the nutritional requirements of common carp than fishmeal. Integration of earthworm production (vermin culture) into small-scale farms in developing countries may open the possibility for farmers in rural areas to engage in semi-intensive aquaculture by using earthworms as a feed ingredient in supplemental feeds for common carp.
