“…We used the model to simulate realistic system behavior, with predicted variables fitting observed data (Morzaria‐Luna, Ainsworth, Kaplan, Levin, & Fulton, ). Fisheries in the model were represented by fleets, including small‐scale, sport fishing, and industrial fisheries, whose simulated spatial use‐patterns and catches reflected our best understanding of recent fishing activity in the region (Moreno‐Báez, Orr, Cudney‐Bueno, & Shaw, ; Rábago‐Quiroz, López‐Martínez, Valdez‐Holguín, & Nevárez Martínez, ). We estimated opportunity cost per fleet based on a 1‐yr forward simulation under modeled 2008 fishing mortality and predicted biomass per functional group and catch per fleet (Data S1), and then summed all fleets for the total cost (Equation ).

. 2018. Designing connected marine reserves in the face of global warming. Global Change Biology 24: e671-e691. https://doi.org/10. 1111/gcb.13989 Designing connected marine reserves in the face of global warming Jorge G. Álvarez-Romero AbstractMarine reserves are widely used to protect species important for conservation and fisheries and to help maintain ecological processes that sustain their populations, including recruitment and dispersal. Achieving these goals requires well-connected networks of marine reserves that maximize larval connectivity, thus allowing exchanges between populations and recolonization after local disturbances. However, global warming can disrupt connectivity by shortening potential dispersal pathways through changes in larval physiology. These changes can compromise the performance of marine reserve networks, thus requiring adjusting their design to account for ocean warming. To date, empirical approaches to marine prioritization have not considered larval connectivity as affected by global warming. Here, we propose a framework for designing marine reserve networks that integrates graph theory and changes in larval connectivity due to potential reductions in planktonic larval duration (PLD) associated with ocean warming, given current socioeconomic constraints. Using the Gulf of California as case study, we assess the benefits and costs of adjusting networks to account for connectivity, with and without ocean warming. We compare reserve networks designed to achieve representation of species and ecosystems with networks designed to also maximize connectivity under current and future ocean-warming scenarios. Our results indicate that current larval connectivity could be reduced significantly under ocean warming because of shortened PLDs. Given the potential changes in connectivity, we show that our graph-theoretical approach based on centrality (eigenvector and distance-weighted fragmentation) of habitat patches can help design better-connected marine reserve networks for the future with equivalent costs. We found that maintaining dispersal connectivity incidentally through representation-only reserve design is unlikely, particularly in regions with strong asymmetric patterns of dispersal connectivity. Our results support previous studies suggesting that, given potential reductions in PLD due to ocean warming, future marine reserve networks would require more and/or larger reserves in closer proximity to maintain larval connectivity.

“…The dominant species of the study; with an IVI greater than 50, contribute with more than 92% of the total abundance, which is typical of catches in the Gulf of California (Rábago-Quiroz et al, 2011). It has even been reported that by-catch may have larger volumes than the target fishery (Barreto, Polo andMancilla, 2001, Gibinkumar et al, 2012).…”

Reproduction and community structure of fish from winter shrimp bycatch from the Southeast Gulf of California Shrimp fishery is one of the most important fisheries of the world. However, the low selectivity from trawl nets leads the capture of a large number of non-target species.Shrimp bycatch include a large number of fish and invertebrate species; of which fish species are the most abundant. The present study aims to determine the community structure as well as the average sizes at first maturity of the fish species from shrimp bycatch caught from industrial fisheries at the southeast of the Gulf of California from Sinaloa to Guerrero, Mexico; from January to March 2015. A total of 37 species of finfish were found; of which five were considered rare. Shrimp fishery is one of the most important fisheries of the world.

The 21 present study aims to determine the community structure as well as the average sizes at first 22 maturity of the fish species from shrimp bycatch caught from industrial fisheries at the southeast 23 of the Gulf of California from Sinaloa to Guerrero, Mexico; from January to March 2015. A total 24 of 37 species of finfish were found; of which five were considered rare. The fish species with the 25 highest Importance Value Index (IVI) were Pseudupeneus grandisquamis, Paralichthys 26 woolmani, Lutjanus peru y Diapterus peruvianus. The average size at first maturity of 12 fish 27 species was determined; nine of which have not been previously reported. Of the analyzed 28 organisms 90% were in juvenile stage; including species with riverine and artisanal fisheries. 29 The present study demonstrates the risk in marine populations of different non-target species due 30 to the low selectivity of shrimp trawls.

“…Therefore, bigger individuals may have a better swimming capacity, evading trawling gear. Additionally, bathymetric distribution may also contribute because the species can be seen in up to 360m in deeper shrimp (Crustacea: Solenoceridae) research surveys using a similar fishing method (Rábago-Quiroz et al 2011). Shrimp commercial vessels operate at shallower waters and mainly on the continental shore (López-Martínez et al 2000, Morales-Azpeitia 2007, while the species distributional so comprises the peninsular side where the platform is much narrower or almost absent (Roberson & Allen 2002).…”

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 populations. With the aim of contributing to the knowledge of Darkedge Midshipman fish Porichthys analis, the most common waste species in this fishery, we estimated some population characteristics. For this purpose, we obtained shrimp-bycatch fish during the 2004-2005 fishing season and performed some research surveys. A total of 1 725 Darkedge Midshipman were captured from 350 bycatch samples. Individual size ranged from 43-352mm SL. The weight to standard length relationship was determined as W=0.000092SL 3.0509. Von Bertalanffy's growth coefficient indicated a moderate growth rate (K=0.5) with an estimated asymptotic length ofL ∞ =352mm standard length, and a longevity of 6yr. Natural mortality was estimated as 0.97 and total mortality as 4.67. The recruitment pattern, as estimated by ELEFAN II, was extended over the year, peaking during spring and summer seasons. Sexual proportion of male:female was 1.65:1. Mature organisms appeared from August to March, and length at maturity was 157mm SL, which is larger than the mean size at capture 135mm SL. We concluded that the species is indirectly protected by its own bathymetric distribution and the off-shrimping season. This is the first study that considers population characteristics from this common but still unknown species.
