Competition and predation are major biotic interactions that influence the structure of aquatic communities. The relative importance of each type of interaction is usually a function of the relative size of the organisms involved. This study used field experiments to assess potential size-dependent interactions among small juvenile killifish (Fundulus heteroclitus) and grass shrimp (Palaemonete...

We report the construction of sex-specific linkage maps for the white shrimp Penaeus (Litopenaeus) vannamei (Penaeidae; Crustacea). Linkage information was generated using amplified fragment length polymorphism (AFLP) markers in a mapping panel consisting of 42 individuals derived from a commercial cross. We used 103 primer combinations that produced 741 segregating bands. From them, 477 segreg...

This study investigated the contribution of shrimp stocks in supporting the production of valuable predator species. Fishery-independent data on white shrimp, brown shrimp, and selected fish species (spotted seatrout, red drum, and southern flounder) were collected from 1986 to 2014 by the Texas Parks and Wildlife Department, and converted to catch-per-unit effort (CPUE). Here, the associations...

Sediment community oxygen consumption (SCOC) is a proxy for organic matter processing and thus provides a useful proxy of benthic ecosystem function. Oxygen uptake in deep-sea sediments is mainly driven by bacteria, and the direct contribution of benthic macro- and mega-infauna respiration is thought to be relatively modest. However, the main contribution of infaunal organisms to benthic respir...

Togok is one of the fishing gear that operated in Kuala Tungkal, Tanjung Jabung Barat Regency, this form a conical net body whose arms are tied to two poles and success catching it relies on currents, togok used by Tungkal fishermen catch rebon shrimp (Acetes japonicas) but operation, there many other types catch. This study aims determine main catch, bycatch, discards, size as well number catc...

Shrimp fishery bycatch of the Gulf of California constitutes a wide variety of highly unknown fish, crustacean, and mollusk species with very low or null economic value, in contrast to those of commercial interest. However, there are no studies yet on the role of these low economic valued species have in the community structure and function, together with their possible effect on commercial pop...

BACKGROUND Allergy to specific shrimp species has not been studied systematically by oral challenges. A comparison of allergy to different shrimp species, especially seawater or freshwater varieties treatment, would be useful in testing shrimp-allergic subjects. OBJECTIVE The aim of the study was to identify cases of specific allergy to seawater shrimp, Penaeus monodon (Pm), or freshwater shr...

Caridean shrimp are a diverse and abundant component of seagrass fauna (De Grave 1999). Seagrass shrimp enhance the nursery function of seagrass habitats and make a valuable indirect contribution to commercial fisheries, as they are an abundant and palatable food source for juvenile fisheries species (Heck et al. 2003). Although phylogeographic studies on caridean shrimp are not uncommon, most ...
