One of the greatest current challenges in aquaculture is the ability to develop new and novel feed sources that are better able to utilize available nutrient and energy inputs. Aquaculture is growing rapidly, but its key inputs, including fishmeal from wild-caught lower trophic-level fish present a number of challenges for industry sustainability. Phytoplankton, bacteria and cyanobacteria have all been used as probiotic supplements in feed, but only more recently as a substitute for protein in feeds. Yet wild fish thrive while ingesting naturally occurring microbial communities (biofilm/periphyton, biofloc) and the use of microorganisms to boost aquaculture performance is not a new practice given that bacteria and yeasts are frequently used in commercial production as pre- and probiotic supplements and immunostimulants. However, only relatively recently have commercial operations demonstrated the utility of microbes as a direct nutrient source for a variety of farmed organisms.

The role of geology behind diatom communities

-

Geological setting in Finland The last glaciation, approximately 10 000 years ago, eroded and deposited material leaving behind a landscape full of glacial landforms in northern Europe. These landforms include thick layers of basal tills, glaciofluvial eskers, and moraines, to name a few. The retreating glacier also left behind a multitude of lakes in Finland. These lakes are often shallow and elongated in the direction of the ice flow. A majority of the lakes are located in central-eastern Finland, called the Finnish Lake District, where a relatively coarse-grained basal till covers most of the land surface. These tills deposited under actively flowing ice lobes that flushed away the finer materials. However, in the intersection of two actively flowing ice lobes, a passive interlobate area formed. This wedge-shaped area pierces central Finland in a NW-SE direction and is characterized by fine-grained basal till. The coastal areas of Finland, on the other hand, were under water ...

Diatom(s) of the Month - November 2017: the recently-digitized Diatom New Taxon File (DNTF) at the Academy of Natural Sciences

by Alison Minerovic* What is the “DNTF”? The Diatom New Taxon File, or “DNTF”, is a digitized card catalog of all published diatom names, along with original descriptions, images, and literature citations of taxa published since 1933. It serves as a resource for diatom scientists, taxonomists, systematists, students, and enthusiasts! Figure 1 . DNTF Homepage (from 25 September 2017). The original card catalog lives in the Diatom Herbarium at the Academy of Natural Sciences in Philadelphia (ANSP), Pennsylvania, USA. Although we no longer add physical cards to the DNTF, Herbarium staff manage and update digital “cards” through our website: http://symbiont.ansp.org/dntf/  (Fig. 1) . Why is the DNTF important? As many of you know, diatom taxonomy – names, descriptions, and classification – is continually changing. Projects like the DNTF are important for maintaining consistent taxonomy, which forms the foundation of all applied diatom research. For example, s...
