Abstract:
The effects on growth performance, feed utilization, survival and whole fish body proximate composition of replacing fishmeal (Rastrineobola argentea) with a locally available spirulina species (Arthrospira fusiformis) as a protein ingredient in the feed of Rufiji tilapia (Oreochromis urolepis urolepis) fry was examined. Fishmeal replacement with A. fusiformis was carried out at 5%, 15%, 25%, 35% and 100% (S5, S15, S25, S35 and S100), and the effect of the replacement was compared with the control diet (S0, 0% spirulina). Fish fry were stocked at an average initial weight of 0.57 g at 10 fish per 0.1 m3 and cultured for 60 days using full strength salt water (30-35 ppt). A. fusiformis was isolated from Momela Lake in Arusha National Park, Tanzania and propagated using selected culture media. It was observed that fish fry fed spirulina at a 5% fishmeal substitution level diet had better (p<0.05) final weight (8.48), average daily weight gain (0.132), specific growth rate (4.47), feed conversion rate (2.08) and protein efficiency ratio (1.37) compared to the control fish group. Growth performance in fish fed diet S15 was comparable with the control group (p>0.05). Spirulina supplementation had no effect on fish survival rates and meat quality. It appears that the Momella Lake spirulina may be an appropriate growth-stimulating plant protein when used as a feed additive in Rufiji tilapia mariculture.

Abstract:
Oreochromis niloticus is the most important aquacultural species worldwide. Several countries are interested in repopulating natural or artificial reservoirs with the fry of tilapia (Oreochromis sp.) to develop new fisheries or to enhance the existing ones. However, as tilapia is considered an invasive species, it is essential to check the existence of the species in the place before releasing any fry. Characterization of tilapia species with meristic is unreliable because of existing morphological similarities among species. In this work, the composition of the tilapia species of Laguna El Mastranzo (LEM), Nayarit, Mexico, was explored for the first time through a molecular method using the mitochondrial DNA control region. Three tilapia species (Oreochromis niloticus, O. aureus, and O. urolepis) were found in LEM, and it was confirmed that the two commercial strains (Aquamol and Spring) intended for repopulation were O. niloticus. Seven haplotypes of mitochondrial DNA control region sequences were obtained: three in LEM, three in Aquamol, and one in Spring strains. Before repopulating any reservoir, a molecular verification strategy is recommended to avoid spreading the species. The results of this work represent a glimpse into the genetic material of LEM, Nayarit, Mexico.

Abstract:
Los peces introducidos pueden amenazar a la biodiversidad acuática. Perú es un país megadiverso; su costa norte (Tumbes, Piura, Lambayeque y La Libertad) presenta una mayor diversidad íctica que su centro y sur. En esta región existen especies introducidas; pero, no se ha encontrado una investigación que consolide los datos sobre las mismas. La investigación tuvo como objetivo preparar una revisión sistemática sobre peces introducidos y potencialmente invasores en la costa norte peruana. Siguiendo las pautas de Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) del 2020, se obtuvieron 2665 documentos de Scopus, WoS, ScienceDirect, SciELO, Pubmed y Google Académico, Tras eliminar documentos duplicados y aplicar los criterios de inclusión y exclusión, se seleccionaron seis documentos. Se añadieron ocho documentos obtenidos de otras fuentes. Se reportaron 12 especies introducidas: carpa (Cyprinus carpio), gambusia (Gambusia affinis), guppy (Poecilia reticulata), pez cola de espada (Xiphophorus hellerii), mojarra (Coptodon rendalli), tilapia azul (Oreochromis aureus), tilapia mosámbica (Oreochromis mossambicus), tilapia nilótica (Oreochromis niloticus), wami tilapia (Oreochromis urolepis), cobia (Rachycentron canadum), trucha arcoíris (Oncorhynchus mykiss) y carachama (Hypostomus sp.). De estas, cinco especies fueron cíclidos y tres poecílidos; once especies se encontraron en agua dulce, cinco en manglares y dos en el mar. Tumbes registró el mayor número de cuerpos de agua con especies introducidas, Piura registró la mayor cantidad de especies (ocho), mientras que en Lambayeque se reportó solo una especie en un cuerpo de agua. Siete especies: carpa, gambusia, guppy, tilapias (azul, mosámbica y nilótica) y trucha arcoíris tienen alto potencial invasor, pues se encuentran entre las 100 peores especies invasoras de Europa o del mundo. Los documentos evaluados solo han reportado la presencia de especies introducidas, sin profundizar en el impacto que han tenido en los ecosistemas; por lo que, sería recomendable realizar investigaciones en esa dirección.

Abstract:
The Salton Sea is a large inland lake in southeastern California with salinity currently near 44 g/l that is increasing at a rate of 0.3 g/l annually. Along with salinity, large fluctuations in temperature and dissolved oxygen levels combine to make a very challenging environment that may be responsible for dramatic losses to the Salton Sea's once robust fishery. The dominant species within the fishery is a Mozambique tilapia hybrid (Oreochromis mossambicus x O. urolepis hornorum), which is well known both for euryhalinity and tolerance of extremely high salinities; as such, it provides a unique model for tolerance to hypersaline conditions as well as the interactions of multiple stressors such as those within the Salton Sea. In part one I describe two responses by tilapia to salinities greater than seawater at 25°C. When transfers were conducted below 60 g/l salinity, tilapia maintained osmotic balance without increasing drinking rate, mitochondrial-rich cell (MRC) turnover, or branchial Na⁺,K⁺-ATPase (NKA) activity. With additional increase above 60 g/l, these variables increased in similar fashion to that which has been described in other teleosts during acclimation to elevated salinity. These acclimation responses were defined as response I or response II, with a transition point between the two at 60 g/l. Tilapia exhibiting response I had a reduced whole animal oxygen consumption rate, as well as, liver and brain ATPase activity in proportion to salinity. In part two, I describe how changes in temperature affect the salinity tolerance of this species. Variation in temperature from 25°C to 15 or 35°C resulted in increased plasma osmolality and/or mortality, indicating a combined temperature/salinity stress is more challenging than salinity alone. Using tissue microarrays and laser scanning microscopy, I show that tilapia attempted to respond to the loss of osmotic balance in cold temperatures with MRC hypertrophy and enhanced NKA capacity.<br>Science, Faculty of<br>Zoology, Department of<br>Graduate
